Release Notes: The in-memory support was revised for improved stability. Additional configuration options for elections and in-memory support were implemented. The replication code was cleaned up and restructured in preparation for beta status.
Release Notes: A race condition leading to duplicate takes of one Entry was fixed.
Release Notes: Support was added for configuring cache sizes per Entry type. A buffering strategy was added to the inter-node messaging infrastructure, yielding better overall performance and faster checkpointing.
Release Notes: Several deadlocks which occur under high load with swapping were fixed. It is now possible to force a single node to boot as master for disaster recovery purposes. An initial memory-only implementation was added.
Release Notes: This release was forward ported to Db 4.3, and Db 4.2.52 is no longer supported. Dashboard and the stats API were updated to provide Entry schema information. Replacement nodes that were introduced as part of disaster recovery are now automatically synchronized with the existing master.
Release Notes: A bug was fixed in meta.Registry where initializer results were not forced to disk which could result in recovery problems. Node failure detection was enhanced to better handle network link-layer problems.
Release Notes: The join process was modified to only start up when there are sufficient replica group members available. Dead replicants are now automatically removed from membership, and temporarily replicant availability problems are now handled properly. The poor operation throughput caused by loss of replicants has been fixed.
Release Notes: A fix was made to initial join/discovery to ensure that the initialGroups configuration variable is honored.
Release Notes: This initial fault tolerance implementation includes fixes from 2.1.12 Server Edition.
