🧵 Performance & Threading model

[Spikhalskiy]

Description

Improve threading model in different areas of JavaSDK

Core Objectives

With the absence of coroutines, we create and use short-living separate Java threads for a lot of things. This is wasteful and can be reworked to pooling, event loops, work-stealing, or any other solution that will minimize threads churning and also will allow management and constraining of resources used by a single workflow.
