## Summary - preserve the local heartbeat timer-task status when replicated heartbeat progress only moves the deadline later - continue invalidating the status for a new activity attempt, options stamp, or cross-cluster version - prevent passive task refresh from creating a duplicate heartbeat timeout task while an earlier valid wake-up is already pending ## Why The active path coalesces heartbeat timeout tasks: recording a heartbeat keeps the earlier pending wake-up, which re-evaluates the latest heartbeat deadline when it fires. State-based replication previously cleared that timer status when the heartbeat deadline moved, causing passive task refresh to create an extra timeout task. ## Testing - `go test ./service/history/workflow -run "^TestMutableStateSuite$" -testify.m "^TestNextActivityTimerTaskMask_" -count=1` - verified with replication multiple batches both enabled and disabled
Temporal—durable execution platform
Introduction • Getting Started • Contributing • Temporal Docs • Temporal 101
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.
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.
temporal operator namespace list
temporal workflow list
Use Temporal Web UI
Try Temporal Web UI by opening http://localhost:8233 for viewing your sample workflows executing on Temporal.
Repository
This repository contains the source code of the Temporal server. To implement Workflows, Activities and Workers, use one of the supported languages.
