The row-level versioning (RLV) store is an in-memory store for high-performance row-level updates. If a table is registered for RLV storage, then all LOAD TABLE, INSERT, UPDATE, and DELETE commands write directly to the RLV store.
Multiple connections can make simultaneous updates to different rows of an RLV-enabled table. In the IQ main store, only one connection can write to a table at one time.
The RLV store periodically, and automatically, merges its in-memory contents with the IQ main store, although you can change merge preferences. You can trigger a manual merge when desired.
For detailed information on using the RLV store to perform real-time concurrent updates, see Administration: In-Memory Row-Level Versioning.
