Release Highlights

• Kafka deprecation: Internal queues are now being used for visibility in a dual processor mode. See details below.
• Bug fixed: When using Cassandra persistence, there was an issue that could have lead to Workflow creation without an initial event.
• Other small bug fixes and refactors: See change details.

Deprecate Kafka

UPDATE: Please use v1.6.4 release to migrate out of Kafka.

This release uses internal visibility queues by default, instead of Kafka. New visibility updates will go to the internal visibility queue but the Kafka processor will still be running in order to process previously created messages. This change will provide a smooth migration (no action required) to the internal visibility queue even if you didn't follow the upgrade steps from the previous v1.5.0 release.

In the next release all remaining Kafka code will be completely removed.

• Authorization code improvements and refactors.
• Small bug fixes.

Schema changes

This release includes schema changes.
Before upgrading your cluster, run the schema tool and upgrade your schema to support version 1.3. For MySQL databases use: temporal-sql-tool, for Cassandra use temporal-cassandra-tool.

Below are a few examples that show how to upgrade "default" and "visibility" schemas for Cassandra.

Run these commands if you "bring your own" database.

temporal-cassandra-tool --tls --tls-ca-file $TLS_CA_FILE --user $CASSANDRA_USER --password $CASSANDRA_PASSWORD \
		--endpoint $CASSANDRA_ENDPOINT --keyspace temporal --timeout 120 update --schema-dir ./schema/cassandra/temporal/versioned
temporal-cassandra-tool --tls --tls-ca-file $TLS_CA_FILE --user $CASSANDRA_USER --password $CASSANDRA_PASSWORD \
		--endpoint $CASSANDRA_ENDPOINT --keyspace temporal_visibility --timeout 120  update --schema-dir ./schema/cassandra/visibility/versioned

Run these commands if you have a localhost installation:

temporal-cassandra-tool --keyspace temporal update -schema-dir schema/cassandra/temporal/versioned
temporal-cassandra-tool --keyspace temporal_visibility update -schema-dir schema/cassandra/visibility/versioned

Deprecate Kafka

UPDATE: Please use 1.5.5 release to migrate out of Kafka.

Because the use of Kafka is deprecated for visibility, to upgrade to this release in a backward compatible way you must perform the following steps:

1. Rollout this release and make sure everything works.
2. Add the following to your dynamic config and then perform a rolling restart:

history.visibilityQueue:
    - value: "internalWithDualProcessor"
      constraints: {}

3. Wait for the Kafka visibility queue to drain. You may monitor the Kafka backlog, but 10 minutes should be enough.
4. Change the history.visibilityQueue dynamic config value from internalWithDualProcessor to internal:

history.visibilityQueue:
    - value: "internal"
      constraints: {}

5. Perform another rolling restart.
6. Kafka and zookeeper are no longer used, and can be removed from the setup.

If it is acceptable to lose some visibility messages you may set the dynamic config value to internal right away or wait for the next release where the default value will be internal.

Release Highlights

This release includes a patch for an issue found in infinite timeout feature, i.e. allowing not setting certain timeout: (https://github.com/temporalio/temporal/releases/tag/v1.4.0).
For details see: #1071 #1073

NOTE: Infinite timeout feature will be the default behavior beginning from v1.5.x

The infinite timeout functionality is by default disabled for forward / backward compatibility.
When deploying a brand new v1.4.x Temporal service, user can set "system.enableInfiniteTimeout" to be true.
When upgrading to v1.4.x Temporal service, user must first deploy the v1.4.x service, then set "system.enableInfiniteTimeout" to be true.

1. In terms of workflow execution timeout (across multiple continue as new / retry runs), setting the WorkflowExecutionTimeout parameter to 0 means no timeout for workflow execution
2. In terms of workflow run timeout (per run ID), setting the WorkflowRunTimeout parameter to 0 means no timeout for this workflow run
3. Additional checks from server logic will guarantee that
   a. when WorkflowExecutionTimeout > 0 && WorkflowRunTimeout > 0 => WorkflowRunTimeout <= WorkflowExecutionTimeout
   b. when WorkflowExecutionTimeout > 0 && WorkflowRunTimeout == 0 => WorkflowRunTimeout = WorkflowExecutionTimeout
   c. when WorkflowExecutionTimeout == 0 => no restriction on WorkflowRunTimeout
4. Activity schedule to start / schedule to close timeout can also be 0 (no timeout) if workflow run timeout is 0 (no timeout)

UPDATE: We have discovered some issue related to v1.4.0 release regarding the infinite timeout feature, please use v1.4.1 instead.

NOTE: The infinite timeout feature is by default disabled for v1.4.x.

Release Highlights

This release contains refactoring, optimizations, bug fixes, metric fixes, support for signed requests to AWS Elastic Search, and significant enhancements to Temporal's Authorization story.

Notable Changes

Persistence Schema:
This release updates the current Persistence store schema. Be sure to upgrade your schema (target version 1.2) before upgrading to the latest server bits.

Authorization:
This release includes a set of features and improvements for authorization. Notably, ClaimMapper and Authorizer plugin interfaces with the corresponding server options for configuring them. This enables a range of authorizations scenarios based on JWT tokens and Mutual TLS certificates. defaultJWTClaimMapper and defaultAuthorizer are included as fully functional examples that can be used as is, or customized for specific use cases. Documentation is in progress.

UPDATE: If you are upgrading from a version older than 1.0.0, use 1.3.1 instead.

Release Highlights

This release contains configuration and API refactors and bug fixes.

Important:

1. The metrics configuration sections were moved from the per service configuration sections to the global section. This will set up a Prometheus listener only once per process (not per hosted service). The old metrics section is still supported but deprecated and will be removed later.
2. The DescribeMutableState API response for adminservice was changed from JSON to Protobuf. This is a breaking change for this API, but it is only being used by the tctl admin command. This means that some admin commands from the previous tctl versions won't work with this server version and vice versa.

UPDATE: This release has few bugs, please use v1.1.1 instead.

Release Highlights

This release includes schema changes.
Before upgrading your cluster, run the schema tool and upgrade your schema to support version 1.1
For MySQL databases use: temporal-sql-tool, for Cassandra use temporal-cassandra-tool.

Below are a few examples that show how to upgrade "default" and "visibility" schemas for Cassandra.

Run these commands if you "bring your own" database.

Default:

temporal-cassandra-tool --tls --tls-ca-file $TLS_CA_FILE --user $CASSANDRA_USER --password $CASSANDRA_PASSWORD \
		--endpoint $CASSANDRA_ENDPOINT --keyspace temporal --timeout 120 update --schema-dir ./schema/cassandra/temporal/versioned

Visibility:

temporal-cassandra-tool --tls --tls-ca-file $TLS_CA_FILE --user $CASSANDRA_USER --password $CASSANDRA_PASSWORD \
		--endpoint $CASSANDRA_ENDPOINT --keyspace temporal_visibility --timeout 120  update --schema-dir ./schema/cassandra/visibility/versioned

Run these commands if you have a localhost installation:

Default:

temporal-cassandra-tool --keyspace temporal update -schema-dir schema/cassandra/temporal/versioned

Visibility:

temporal-cassandra-tool --keyspace temporal_visibility update -schema-dir schema/cassandra/visibility/versioned

Release Highlights

v0.31.0 maintains Temporal's "Alpha" release state. Please do not use this release for production workloads.

Important
This release contains hotfixes. The most critical one (#740) fixes an issue that prevented the server from spinning up multiple times via docker-compose.

Things we are still working on

1. Stress and Performance testing.
2. Failure testing.

UPDATE: Due to #740 bug docker-compose version of the server can't be started more than once. Please use v0.31.0 instead.

Release Highlights

v0.30.0 maintains Temporal's "Alpha" release state. Please do not use this release for production workloads.

Important

1. You can not rollback to a previous version once you have upgraded to v0.30.0. Data that is created in v0.30.0 is not supported by older versions and you will get panic: runtime error: invalid memory address or nil pointer dereference when the service tries to start. Using an older version after the upgrade will require a fresh install.

2. After upgrading to v0.30.0 you can not call Reset on Workflows which were started with a previous version. However, you can still call Reset on Workflows that were started while running v0.30.0.
