1. Snapshot now passed db index and rdb save handles by inserting select opcodes when needed.
2. Fix few more bugs in CVCUponInsert.
3. Save lua scripts.
1. Fix a bug in dash table related to snapshotting.
2. Rewrite GlobalState code and make state transitions atomic and well defined.
3. Fix Save/Flush semantics by capturing snapshotted tables together with the snapshot.
1. Make EngineShardSet to be a process singleton instead of a variable passed everywhere.
2. Implement a heuristic of updating free memory per shard.
3. Make sure that SET command returns OOM when a database reaches its limits.
1. Added support of loading of compressed strings.
2. Verified we load expiry info.
3. Extended supported expiry period to 4 years (previously I set 1 year).
1. Basic support of sets and hsets. No intset or dict-based hset yet.
2. Make sure that rdbloader actually loads the data into shards.
3. Support object metadata like expiry time.
4. Support lists loading.
1. Sets do not use anymore redis encoding constants in our codebase.
2. rdb_save serializes now expiry information as well.
3. db_slice provides a simplified api to translate from absolute time to ExpirePeriod.
4. common_types.h is renamed to common.h. cached memory usage variables are moved there.
