Creating replicas from across storage groups of a time series database

Abstract:

Creating replicas of a time series database from across storage groups may be implemented for a time series database. Updates to a time series database may be maintained in an update log. Updates may be obtained from the log and ingested at different groups of copies of the time series database used to perform queries. Updates may be ingested at different rates at the different groups. A new copy may be added to one of the groups by copying a portion of the time series database for the new copy determined to be present in another group of copies and an update not found in the other from the log to the new copy.
