stream_flush_interval_ms
Works for tables with streaming in the case of a timeout, or when a thread generates max_insert_block_size rows.
The default value is 7500.
The smaller the value, the more often data is flushed into the table. Setting the value too low leads to poor performance.
stream_poll_timeout_ms
Timeout for polling data from/to streaming storages.
