Roman Puchkovskiy updated IGNITE-21144:
---------------------------------------
Description:
Futures returned by the PlacementDriver might be completed in the Metastorage
watch threads, which are critical and hence should not be used for heavy
(potentially I/O-bound) computations which are possible when accessing
storages. So after such futures complete, the control should be returned to the
partition-operations executor.
IGNITE-21079 fixes this for calls to SchemaSyncService and RaftGroupService by
introducing decorators around them. The same should be done for calls to
PlacementDriver.
