FLUSH RAMCHUNK rt_table

The FLUSH RAMCHUNK command creates a new disk chunk in an RT table.

Normally, an RT table would automatically flush and convert the contents of the RAM chunk into a new disk chunk once the RAM chunk reaches the maximum allowed rt_mem_limit size. However, for debugging and testing purposes, it might be useful to forcibly create a new disk chunk, and the FLUSH RAMCHUNK statement does exactly that.

FLUSH TABLE rt_table

FLUSH TABLE forcefully flushes RT table RAM chunk contents to disk.

The real-time table RAM chunk is automatically flushed to disk during a clean shutdown, or periodically every rt_flush_period seconds.

Issuing a FLUSH TABLE command not only forces the RAM chunk contents to be written to disk but also triggers the cleanup of binary log files.
