Release Notes for mongosync 1.5
1.5.0 Release
July 25, 2023
Oplog Rollover Resiliency
Starting in 1.5.0, mongosync
begins to apply changes while the
initial sync is still in progress. By starting to apply changes earlier,
mongosync
maintains a more recent position in the oplog.
This adds resiliency to long-running operations, mitigates the risk
of oplog
rollover, and significantly lowers the risk of restarting
the sync.
Logging Level
Starting in 1.5.0, the default logging level is DEBUG
. To change
the logging level, see the verbosity
setting.
Bug Fixes
Fixes an issue where very large collections could timeout during
mongosync
initialization.Fixes an issue where
mongosync
could incorrectly report indexes as mismatched.Fixes an issue where the /start endpoint would not return an error when passed a
sharding
object without theshardingEntries
key.Changes telemetry to send less metadata to Segment.
Minimum Supported Version
In 1.5, the minimum supported version of MongoDB is 6.0.8.
