ClickHouse Defaults to Async INSERTs in Patch Release 26.2.4
ClickHouse's 26.2.4 patch introduces default asynchronous INSERT operations, optimizing data flow and eliminating certain errors.
In the 26.2.4 patch release, ClickHouse changed its default behavior for INSERT operations to asynchronous. This update allows small INSERTs to be batched together, eliminating the "Too many parts" error. However, the wait_for_async_insert setting remains at 1, meaning clients will block until the flush occurs.
