Mistral engine now supports graceful scale-in. That is, if a number of
|
|
engines in a cluster needs to be reduced manually it is now possible to
|
|
do w/o breaking currently running workflows. In order to shutdown a
|
|
Mistral engine, SIGTERM signal needs to be sent to the corresponding
|
|
process. In Unix operatating systems it's a matter of running the command
|
|
"kill <engine PID>" in any shell. When this signal is caught by the
|
|
process, it has a certain amount of time configured by the
|
|
'graceful_shutdown_timeout' property to complete currently running
|
|
database transactions and process all buffered RPC messages that have
|
|
already been polled from the queue. After this time elapses, the process
|
|
will be forced to exit.
|
|
By default, the value of the 'graceful_shutdown_timeout' property is
|
|
60 (seconds).
