We have some application code running inside the regionserver. It atomically updates a row and maintains a count of the number of entries inside that row. The reason it is part of the region server code is because we need the 'count' updation to be atomic and performant read-modify-write. The code to read the previous value of the 'count' will invoke getScanner(scan, Long.Max_VALUE) so that it can read the most recent value of 'count' (even if the previous 'count' update is still in the process of getting committed). > Create a HRegion.getScanner public method that allows reading from a > specified readPoint > > > Key: HBASE-4938 > URL: https://issues.apache.org/jira/browse/HBASE-4938 > Project: HBase > Issue Type: Improvement >Reporter: dhruba borthakur >Assignee: dhruba borthakur >Priority: Minor > > There is an existing api HRegion.getScanner(Scan) that allows scanning a > table.

[jira] [Commented] (HBASE-4938) Create a HRegion.getScanner public method that allows reading from a specified readPoint
[ https://issues.apache.org/jira/browse/HBASE-4938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161838#comment-13161838 ] dhruba borthakur commented on HBASE-4938: - This is a very minor restarting of the code. We have some internal HRegion API that needs to scan based on a external readPoint. Of course, we could duplicate this piece of code from HRegion.java into our own code base, but in the spirit of making all our code changes compatible with Apache copen source, I would like to request the community to analyze this requested code change and approve of it. I will provide a patch. > Create a HRegion.getScanner public method that allows reading from a > specified readPoint > > > Key: HBASE-4938 > URL: https://issues.apache.org/jira/browse/HBASE-4938 > Project: HBase > Issue Type: Improvement >Reporter: dhruba borthakur >Assignee: dhruba borthakur >Priority: Minor > > There is an existing api HRegion.getScanner(Scan) that allows scanning a > table.
