Implemented SYSTEM Start/stop DISTRIBUTED SENDS Queries to Control Asynchronous Inserts into Distributed Tables

Why it matters

This feature allows users to manage and control the flow of asynchronous inserts into Distributed tables by starting or stopping the sending of data streams. It helps in scenarios where users want to temporarily pause or resume data sending without dropping connections or tables, improving operational control and stability.

How to use it

To use this feature, execute the following commands:

SYSTEM STOP DISTRIBUTED SENDS
SYSTEM START DISTRIBUTED SENDS

These commands will respectively pause and resume the asynchronous inserts for Distributed tables across the cluster.
