Introduction

Finite State Machine and/or Workflow provides the deterministic paradigm to the software application development. Temporal addresses the Workflow part of the paradigm. Hopefully Temporal also addresses the Finite State Machine part of the paradigm. Let research into the technologies to find out if one could start with:

The Workflow specification to the Temporal framework OR
The Finite State Machine specification to the Temporal framework Further study into few internet pointers, It seems that TO-DO must be required to see how FSM and Temporal Workflow

Temporal Cluster

At the heart of the Temporal framework is the cluster. It provides the deterministic mechanism to the workflow using kafka and g- rpc //TO-DO further study required. The Temporal cluster can be run as

Standalone process
- For Mac

brew install temporal 
OR
curl -sSf https://temporal.download/cli.sh | sh
temporal server start-dev
For a full list of options, run:
temporal server start-dev --help

The Temporal Server should be available on localhost:7233 and the Temporal Web UI should be accessible at http://localhost:8233.

For Linux (To be added)
For Windows (To be added)
Docker/Kubernetes: prefer method to run Temporal cluster More to find out at here

Temporal Lite

Reference 1 Temporal Getting Started Guide Temporal Lite and GoLand The objectives to run Temporalite with the ability to debug using JetBrains GoLand:

To understand how various temporal components work together
To run the temporalite as docker (We still think to run it as temporalite docker as part of the development)
To debug the application development
To perform integration test during the development
etc…

Temporal API

Temporal Cluster

[Temporal API Github] (https://github.com/henrynguyenattheitservice/temporal-api-java.git)

gRPC Services sepecifies in the protobuf files.

We build the temporal API using JetBrains IntelliJ and JetBrains GoLand and see how the generated code used in the development of Java-SDK and Go-SDK. The objectives of the TemporalAPI are

To understand the SDK Wrapper
To understand the Temporal Server activities via debugging the Temporalite using JetBrains GoLand
etc…

TemporalLite Database

Temporal UI Temporal Database Schema The objectives of the Temporal Database are

To understand the data and/or information are being persisted
To understand the data and/or information are being persisted when the temporal server crashes and recoveries
etc…
