> Currently, there is no way to synchronize datamaps manually to the fact
> table. So at first added the functionality to load the datamaps manually by
> using command {{refresh}}
> {{REFRESH DATAMAP <datamapName> }}
> Above command syncs the data between the datamap and parent tables.
> In order maintain the data consistency we require to enable or disable
> datamaps when data is not synchronized between fact and datamap. So added the
> new status called datamapstatus file under the system folder. whenever the
> data is out of sync between parent tables and datamap it just updates the
> status as disabled in datamapstatus file. After user manually refreshes the
> datamap it will update the status to enable.
> Only the enabled datamaps are considered during query.
