I have a MapR DB binary table where records get created/updated in near realtime from a Cloud system. The rowkey is a unique number which corresponds to the record key in the cloud system. We use this key to insert/update record into the table. I want to fetch the records created or modified between two timestamps from the mapr table. I do have some date fields in the column family. But applying a column filter on those will cause a full tablescan. Is there any other MapRDB internal timestamp columns that I can use to achieve this ?
