Bug fixes
-
In TokuMX 1.3.2 and earlier, part of the oplog trimming process (an optimization step) tended to hold a read lock for long periods of time. Now in 1.3.3, this component works in 4-second periods, which is configurable with the parameter
optimizeOplogQuantum
, which can be set dynamically withsetParameter
. (#777)Valid values are:
-
N > 0
: Work in periods ofN
seconds. -
N = 0
: Do not optimize the oplog at all. -
N < 0
: The 1.3.2 behavior, optimize aggressively without yielding.
-
-
Removed an unnecessary step in a replica set secondary's startup process that had the potential to cause long stalls and pileups. (#806)
-
Certain query operations sometimes spend a long time in the storage layer, searching through entries that were deleted but not garbage collected. Added a mechanism by which such operations can be killed like normal operations. (#813)
