Abstract
An event historian system merges stored event data snapshots into sorted event storage blocks. The system determines that a storage block contains a plurality of snapshots to be merged. A new snapshot is created into which the plurality of snapshots will be merged. The event data within the snapshots is combined and recorded into the new snapshot in a sorted order. The index files within the snapshots are combined and recorded into the new snapshot.
