Introduction

Temporal is a durable execution platform that enables developers to build scalable applications without sacrificing productivity or reliability.
The Temporal server executes units of application logic called Workflows in a resilient manner that automatically handles intermittent failures, and retries failed operations.

Temporal is a mature technology that originated as a fork of Uber's Cadence.
It is developed by Temporal Technologies, a startup by the creators of Cadence.

Getting Started

Download and Start Temporal Server Locally

Execute the following commands to start a pre-built image along with all the dependencies.

bash

brew install temporal
temporal server start-dev

Refer to Temporal CLI documentation for more installation options.

Run the Samples

Clone or download samples for Go or Java and run them with the local Temporal server.
We have a number of HelloWorld type scenarios available, as well as more advanced ones. Note that the sets of samples are currently different between Go and Java.

Use CLI

Use Temporal CLI to interact with the running Temporal server.

bash

temporal operator namespace list
temporal workflow list

TLS Test Data

This directory contains various TLS-related files generated using OpenSSL. The set includes private keys, valid certificates, and intentionally invalid certificates for testing purposes.

Overview

Important: The localhost.cnf file, which contains configuration details for the localhost server, cannot be regenerated as it was manually created.
Private keys (*.key) are RSA keys. Exact regeneration commands are unspecified, but their recreation may not be necessary.
Certificates (*.crt) include a valid Certificate Authority (CA), a valid server certificate, an invalid CA, and an invalid server certificate.

Private Keys Generation

Several RSA private keys were initially generated and are stored in *.key files. The specific configuration of these keys is not documented, but they were likely generated with commands similar to the following:

shell

openssl genrsa -out ca.key 2048
openssl genrsa -out invalid_ca.key 2048
openssl genrsa -out localhost.key 2048
openssl genrsa -out invalid_localhost.key 2048

Note: Regenerating private keys should not be necessary for testing, as the relevant information is embedded within the certificates.

Certificates

Valid Certificate Authority (CA)

File: ca.crt
Description: Self-signed CA certificate.

Regeneration Command:

shell

# Generate a new CSR for the CA
openssl req -new -key ca.key -out ca.csr -nodes -batch

# Self-Sign the new CA certificate
openssl x509 -req -in ca.csr -signkey ca.key -out ca.crt -days 36500 -sha256

# Verify the new CA certificate
openssl verify -CAfile ca.crt ca.crt

# Clean up the CSR
rm ca.csr

Note: The CA is set with a 100-year expiry to avoid frequent regeneration.

Valid Server Certificate

File: localhost.crt
Description: Server certificate signed by the valid CA.

Regeneration Command:

shell

openssl req -new -key localhost.key -out localhost.csr -config localhost.cnf
openssl x509 -req -in localhost.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out localhost.crt -days 36500 -sha256 -extensions req_ext -extfile localhost.cnf
openssl verify -CAfile ca.crt localhost.crt
rm ca.srl localhost.csr

Note: Includes 127.0.0.1 as an IP SAN. Regeneration or resigning is not required if the CA certificate changes but its private key remains the same.

Invalid CA

File: invalid_ca.crt
Description: Another CA certificate that client systems should not trust.

Regeneration Command:

shell

openssl req -new -key invalid_ca.key -out invalid_ca.csr -nodes -batch
openssl x509 -req -in invalid_ca.csr -signkey invalid_ca.key -out invalid_ca.crt -days 36500 -sha256
openssl verify -CAfile invalid_ca.crt invalid_ca.crt
rm invalid_ca.csr

Invalid Server Certificate

File: invalid_localhost.crt
Description: A self-signed server certificate expected to be rejected by clients.

Regeneration Command:

shell

openssl req -new -key invalid_localhost.key -out invalid_localhost.csr -config localhost.cnf
openssl x509 -req -in invalid_localhost.csr -signkey invalid_localhost.key -out invalid_localhost.crt -days 36500 -sha256
openssl verify -CAfile invalid_localhost.crt invalid_localhost.crt
rm invalid_localhost.csr

Google Storage blobstore

Configuration

See https://cloud.google.com/docs/authentication#service-accounts to understand how is made the authentication against google cloud storage

Nowdays we support three different ways in order to let Temporal know where your google keyfile credentials are located

Temporal archival deployment.yaml configuration file
GOOGLE_APPLICATION_CREDENTIALS environment variable
Google default credentials location

If more than one credentials location is given, then Temporal will resolve the conflicts by the following priority:

GOOGLE_APPLICATION_CREDENTIALS > Temporal archival deployment.yaml > Google default credentials

Be sure that you have created your bucket first, and have enought rights in order to read/write over your bucket.

Gcloud Archival example

Enabling archival is done by using the configuration below. credentialsPath is required but could be empty "" in order to allow a Google default credentials.

text

archival:
  history:
    state: "enabled"
    enableRead: true
    provider:
      gstorage:
        credentialsPath: "/tmp/keyfile.json"
  visibility:
    state: "enabled"
    enableRead: true
    provider:
      gstorage:
        credentialsPath: "/tmp/keyfile.json"

namespaceDefaults:
  archival:
    history:
      state: "enabled"
      URI: "gs://my-bucket-cad/temporal_archival/development"
    visibility:
      state: "enabled"
      URI: "gs://my-bucket-cad/temporal_archival/visibility"

Visibility query syntax

You can query the visibility store by using the tctl workflow listarchived command

The syntax for the query is based on SQL

Supported column names are

WorkflowType String
WorkflowID String
StartTime Date
CloseTime Date
SearchPrecision String - Day, Hour, Minute, Second

One of these fields are required, StartTime or CloseTime and they are mutually exclusive and also SearchPrecision.

Searching for a record will be done in times in the UTC timezone

SearchPrecision specifies what range you want to search for records. If you use SearchPrecision = 'Day'
it will search all records starting from 2020-01-21T00:00:00Z to 2020-01-21T59:59:59Z

Limitations

The only operator supported is =
Currently It's not possible to guarantee the resulSet order, specially if the pageSize it's fullfilled.

Example

Searches the first 20 records for a given day 2020-01-21

./tctl --ns samples-namespace workflow listarchived -ps="20" -q "StartTime = '2020-01-21T00:00:00Z' AND SearchPrecision='Day'"

Archival query syntax

Once you have a workflowId and a runId you can retrieve your workflow history.

example:

./tctl --ns samples-namespace workflow show -w workflow-id -r runId

File: common/archiver/s3store/README.md

Amazon S3 blobstore

Configuration

See https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html#specifying-credentials on how to set up authentication against s3

Enabling archival is done by using the configuration below. Region and bucket URI are required

text

archival:
  history:
    state: "enabled"
    enableRead: true
    provider:
      s3store:
        region: "us-east-1"
        logLevel: 0
  visibility:
    state: "enabled"
    enableRead: true
    provider:
      s3store:
        region: "us-east-1"
        logLevel: 0

namespaceDefaults:
  archival:
    history:
      state: "enabled"
      URI: "s3://"
    visibility:
      state: "enabled"
      URI: "s3://"

Visibility query syntax

You can query the visibility store by using the tctl workflow listarchived command

The syntax for the query is based on SQL

Supported column names are

WorkflowId String
WorkflowType String
WorkflowTypeName String (legacy alias)
StartTime Date
CloseTime Date
SearchPrecision String - Day, Hour, Minute, Second

WorkflowId or WorkflowType is required. WorkflowTypeName is still accepted as a legacy alias. If filtering on date use StartTime or CloseTime in combination with SearchPrecision.

Searching for a record will be done in times in the UTC timezone

SearchPrecision specifies what range you want to search for records. If you use SearchPrecision = 'Day'
it will search all records starting from 2020-01-21T00:00:00Z to 2020-01-21T59:59:59Z

Limitations

The only operator supported is = due to how records are stored in s3.

Example

Searches for all records done in day 2020-01-21 with the specified workflow id

./tctl --ns samples-namespace workflow listarchived -q "StartTime = '2020-01-21T00:00:00Z' AND WorkflowId='workflow-id' AND SearchPrecision='Day'"

Storage in S3

Workflow runs are stored in s3 using the following structure

text

s3:///<namespace-id>/
	history/<workflow-id>/<run-id>
	visibility/
            workflowTypeName/<workflow-type-name>/
                startTimeout/2020-01-21T16:16:11Z/<run-id>
                closeTimeout/2020-01-21T16:16:11Z/<run-id>
            workflowID/<workflow-id>/
                startTimeout/2020-01-21T16:16:11Z/<run-id>
                closeTimeout/2020-01-21T16:16:11Z/<run-id>

Enable AWS SDK Logging with config parameter logLevel. For example enable debug logging with logLevel: 4096. Possbile Values:

LogOff = 0 = 0x0
LogDebug = 4096 = 0x1000
LogDebugWithSigning = 4097 = 0x1001
LogDebugWithHTTPBody = 4098 = 0x1002
LogDebugWithRequestRetries = 4100 = 0x1004
LogDebugWithRequestErrors = 4104 = 0x1008
LogDebugWithEventStreamBody = 4112 = 0x1010
LogDebugWithDeprecated = 4128 = 0x1020

Permissions

Your s3 user must have at least the following permissions:

s3:ListBucket
s3:GetObject
s3:PutObject

Using localstack for local development

Install awscli from here
Install localstack from here
Launch localstack with SERVICES=s3 localstack start
Create a bucket using aws --endpoint-url=http://localhost:4566 s3 mb s3://temporal-development

File: common/archiver/README.md

What

This README explains how to add new Archiver implementations.

There are two approaches:

Built-in implementation — add the archiver directly to this repository (e.g., filestore, gcloud, s3store). We are not currently accepting contributions for new built-in archiver implementations. Maintaining a growing set of built-in implementations places an ongoing maintenance burden on the team, so new implementations should use Option 2 instead.
Custom implementation via server option — implement the archiver in an external package and inject it into the server at startup using WithCustomHistoryArchiverFactory / WithCustomVisibilityArchiverFactory. This is the recommended approach for all new archiver implementations.

Option 1: Built-in implementation (in-repo)

Step 1: Create a new package for your implementation

Create a new directory in the archiver folder. The structure should look like the following:

text

./common/archiver
  - filestore/                      -- Filestore implementation
  - provider/
      - provider.go                 -- Provider of archiver instances
  - yourImplementation/
      - historyArchiver.go          -- HistoryArchiver implementation
      - historyArchiver_test.go     -- Unit tests for HistoryArchiver
      - visibilityArchiver.go       -- VisibilityArchiver implementations
      - visibilityArchiver_test.go  -- Unit tests for VisibilityArchiver

Step 2: Implement the HistoryArchiver interface

type HistoryArchiver interface {
    // Archive is used to archive a workflow history. When the context expires the method should stop trying to archive.
    // Implementors are free to archive however they want, including implementing retries of sub-operations. The URI defines
    // the resource that histories should be archived into. The implementor gets to determine how to interpret the URI.
    // The Archive method may or may not be automatically retried by the caller. The ArchiveOptions are used
    // to interact with these retries including giving the implementor the ability to cancel retries and record progress
    // between retry attempts.
    // This method will be invoked after a workflow passes its retention period.
    // It's possible that this method will be invoked for one workflow multiple times and potentially concurrently,
    // implementation should correctly handle the workflow not exist case and return nil error.
    Archive(context.Context, URI, *ArchiveHistoryRequest, ...ArchiveOption) error

    // Get is used to access an archived history. When context expires method should stop trying to fetch history.
    // The URI identifies the resource from which history should be accessed and it is up to the implementor to interpret this URI.
    // This method should thrift errors - see filestore as an example.
    Get(context.Context, URI, *GetHistoryRequest) (*GetHistoryResponse, error)

    // ValidateURI is used to define what a valid URI for an implementation is.
    ValidateURI(URI) error
}

Step 3: Implement the VisibilityArchiver interface

type VisibilityArchiver interface {
    // Archive is used to archive one workflow visibility record.
    // Check the Archive() method of the HistoryArchiver interface in Step 2 for parameters' meaning and requirements.
    // The only difference is that the ArchiveOption parameter won't include an option for recording process.
    // Please make sure your implementation is lossless. If any in-memory batching mechanism is used, then those batched records will be lost during server restarts.
    // This method will be invoked when workflow closes. Note that because of conflict resolution, it is possible for a workflow to through the closing process multiple times, which means that this method can be invoked more than once after a workflow closes.
    Archive(context.Context, URI, *ArchiveVisibilityRequest, ...ArchiveOption) error

    // Query is used to retrieve archived visibility records.
    // Check the Get() method of the HistoryArchiver interface in Step 2 for parameters' meaning and requirements.
    // The request includes a string field called query, which describes what kind of visibility records should be returned. For example, it can be some SQL-like syntax query string.
    // Your implementation is responsible for parsing and validating the query, and also returning all visibility records that match the query.
    // Currently the maximum context timeout passed into the method is 3 minutes, so it's ok if this method takes a long time to run.
    Query(context.Context, URI, *QueryVisibilityRequest) (*QueryVisibilityResponse, error)

    // ValidateURI is used to define what a valid URI for an implementation is.
    ValidateURI(URI) error
}

Step 4: Update provider to provide access to your implementation

Modify the ./provider/provider.go file so that the ArchiverProvider knows how to create an instance of your archiver.
Also, add configs for you archiver to static yaml config files and modify the HistoryArchiverProvider
and VisibilityArchiverProvider struct in the ../common/service/config.go accordingly.

Option 2: Custom implementation via server option (external package)

This approach lets you define archiver implementations in your own codebase and inject them into the Temporal server at startup, without modifying the server source.

Step 1: Implement the HistoryArchiver and VisibilityArchiver interfaces

Same interfaces as Steps 2 and 3 above.

Step 2: Implement CustomHistoryArchiverFactory and/or CustomVisibilityArchiverFactory

// CustomHistoryArchiverFactory constructs a history archiver for a given URI scheme.
// Return provider.ErrUnknownScheme to fall back to the built-in implementation for that scheme.
// If a non-nil archiver is returned, it takes precedence over built-in archiver implementations.
type CustomHistoryArchiverFactory interface {
    NewCustomHistoryArchiver(provider.NewCustomHistoryArchiverParams) (archiver.HistoryArchiver, error)
}

// CustomVisibilityArchiverFactory constructs a visibility archiver for a given URI scheme.
// Return provider.ErrUnknownScheme to fall back to the built-in implementation for that scheme.
// If a non-nil archiver is returned, it takes precedence over built-in archiver implementations.
type CustomVisibilityArchiverFactory interface {
    NewCustomVisibilityArchiver(provider.NewCustomVisibilityArchiverParams) (archiver.VisibilityArchiver, error)
}

The params structs provide everything your factory needs to construct an archiver:

type NewCustomHistoryArchiverParams struct {
    Scheme           string
    ExecutionManager persistence.ExecutionManager
    Logger           log.Logger
    MetricsHandler   metrics.Handler
    Configs          map[string]any  // from archival.history.provider.customStores.<scheme> in config yaml
}

type NewCustomVisibilityArchiverParams struct {
    Scheme         string
    Logger         log.Logger
    MetricsHandler metrics.Handler
    Configs        map[string]any  // from archival.visibility.provider.customStores.<scheme> in config yaml
}

Example factory implementation using the functional adapter types:

historyFactory := provider.CustomHistoryArchiverFactoryFunc(func(params provider.NewCustomHistoryArchiverParams) (archiver.HistoryArchiver, error) {
    if params.Scheme != "myscheme" {
        return nil, provider.ErrUnknownScheme
    }
    return mypackage.NewHistoryArchiver(params.ExecutionManager, params.Logger, params.MetricsHandler, params.Configs)
})

visibilityFactory := provider.CustomVisibilityArchiverFactoryFunc(func(params provider.NewCustomVisibilityArchiverParams) (archiver.VisibilityArchiver, error) {
    if params.Scheme != "myscheme" {
        return nil, provider.ErrUnknownScheme
    }
    return mypackage.NewVisibilityArchiver(params.Logger, params.MetricsHandler, params.Configs)
})

Step 3: Register the factories with the server

Pass the factories as server options when constructing the Temporal server:

s, err := temporal.NewServer(
    temporal.WithConfig(cfg),
    temporal.WithCustomHistoryArchiverFactory(historyFactory),
    temporal.WithCustomVisibilityArchiverFactory(visibilityFactory),
    // ... other options
)

Step 4: Configure archival in your YAML config

Enable archival and configure the URI scheme for your implementation. Use customStores to pass arbitrary config key-values to your factory:

yaml

archival:
  history:
    state: "enabled"
    enableRead: true
    provider:
      customStores:
        myscheme:              # must match the scheme in your URIs
          endpoint: "https://my-storage.example.com"
          bucketName: "temporal-history"
  visibility:
    state: "enabled"
    enableRead: true
    provider:
      customStores:
        myscheme:
          endpoint: "https://my-storage.example.com"
          bucketName: "temporal-visibility"

namespaceDefaults:
  archival:
    history:
      state: "enabled"
      URI: "myscheme://temporal-history"
    visibility:
      state: "enabled"
      URI: "myscheme://temporal-visibility"

The customStores.<scheme> map is passed as Configs in the params to your factory. Built-in schemes (filestore, gstorage, s3store) continue to use their own config sections unless your factory handles them (see FAQ below).

FAQ

If my Archive method can automatically be retried by caller how can I record and access progress between retries?

ArchiverOptions is used to handle this. The following shows and example:

func (a *Archiver) Archive(
  ctx context.Context,
  URI string,
  request *ArchiveRequest,
  opts ...ArchiveOption,
) error {
  featureCatalog := GetFeatureCatalog(opts...) // this function is defined in options.go

  var progress progress

  // Check if the feature for recording progress is enabled.
  if featureCatalog.ProgressManager != nil {
    if err := featureCatalog.ProgressManager.LoadProgress(ctx, &prevProgress); err != nil {
      // log some error message and return error if needed.
    }
  }

  // Your archiver implementation...

  // Record current progress
  if featureCatalog.ProgressManager != nil {
    if err := featureCatalog.ProgressManager.RecordProgress(ctx, progress); err != nil {
      // log some error message and return error if needed.
    }
  }
}

If my Archive method encounters an error which is non-retryable how do I indicate that the caller should not retry?

func (a *Archiver) Archive(
  ctx context.Context,
  URI string,
  request *ArchiveRequest,
  opts ...ArchiveOption,
) error {
  featureCatalog := GetFeatureCatalog(opts...) // this function is defined in options.go

  err := youArchiverImpl()
  if nonRetryableErr(err) {
    if featureCatalog.NonRetryableError != nil {
      return featureCatalog.NonRetryableError() // when the caller gets this error type back it will not retry anymore.
    }
  }
}

How does my history archiver implementation read history?

The archiver package provides a utility class called HistoryIterator which is a wrapper of ExecutionManager.
Its usage is simpler than ExecutionManager, so archiver implementations can choose to use it when reading workflow histories.
See the historyIterator.go file for more details.
Sample usage can be found in the filestore historyArchiver implementation.

Can a custom factory override a built-in scheme like filestore?

Yes. The custom factory is always consulted first. If your factory returns a non-nil archiver for a scheme that is also built-in (e.g., filestore), your implementation takes precedence and the built-in one is never used. Only return ErrUnknownScheme for schemes you want to delegate to the built-in implementations.

Note that when overriding a built-in scheme, the Configs field in the params is populated from customStores.<scheme> — not from the built-in config section (e.g., filestore:). If you need those config values, read them from customStores instead.

Should my archiver define all its own error types?

Each archiver is free to define and return any errors it wants. However many common errors which
exist between archivers are already defined in constants.go.

Is there a generic query syntax for visibility archiver?

Currently no. But this is something we plan to do in the future. As for now, try to make your syntax similar to the one used by our advanced list workflow API.

File: common/effect/README.md

See docs/architecture/effect-package.md.

File: common/primitives/README.MD

The primitives package is meant to contain definitions and constants
that are widely used throughout this repository.

There should serve as the root package in that there should be no imports of any other Temporal package.

File: config/dynamicconfig/README.md

Use development-*.yaml file to override the default dynamic config value (they are specified
when creating the service config).

Each key can have zero or more values and each value can have zero or more constraints.
There are only three types of constraint:

namespace: string
taskQueueName: string
taskType: int (1:Workflow, 2:Activity)

A value will be selected and returned if all its has exactly the same constraints
as the ones specified in query filters (including the number of constraints).

Please use the following format:

yaml

testGetBoolPropertyKey:
  - value: false
  - value: true
    constraints:
      namespace: "global-samples-namespace"
  - value: false
    constraints:
      namespace: "samples-namespace"
testGetDurationPropertyKey:
  - value: "1m"
    constraints:
      namespace: "samples-namespace"
      taskQueueName: "longIdleTimeTaskqueue"
testGetFloat64PropertyKey:
  - value: 12.0
    constraints:
      namespace: "samples-namespace"
testGetMapPropertyKey:
  - value:
      key1: 1
      key2: "value 2"
      key3:
        - false
        - key4: true
          key5: 2.0
