Tuning for Recovery
You have a large database that contains a single large table with two projections, and with default settings, recovery is taking too long. You want to give recovery more memory to improve speed.
Set PLANNEDCONCURRENCY and MAXCONCURRENCY in the RECOVERY pool to 1, so recovery can take as much memory as possible from the GENERAL pool and run only one thread at once.
This setting can slow down other queries in your system.
