RLV Log

RLV store logging is different, and in many ways simpler, than traditional database (disk or in-memory) logging. because data in the RLV store is transient. Data pages are not persisted to disk, and data is merged to the IQ main store on a frequent basis. 

• Log Space Usage
  RLV log space usage is reported by the sp_iqtablesize stored procedure.
• Commit Log
  The commit log is a specialized log stream which speeds the analysis pass during recovery.
