By setting async_insert to 1, ClickHouse first stores the incoming inserts into an in-memory buffer before flushing them regularly to disk. There are two possible conditions that can cause ClickHouse to flush the buffer to disk: buffer size has reached N bytes in size (N is configurable via...

On client it can be enabled by setting async_insert for INSERT queries with data inlined in query or in separate buffer (e.g. for INSERT queries via HTTP protocol). If wait_for_async_insert is true (by default) the client will wait until data will be flushed to table. On server-...
Initial support of async sockets for remote queries. #17868 (Nikolai Kochetov). Allow to use optimize_move_to_prewhere optimization with compact parts, when sizes of columns are unknown. #17330 (Anton Popov). Improvement Avoid deadlock when executing INSERT SELECT into itself from a table with...
