Subject [jira] [Commented] (TEPHRA-274) Handle Filters in preFlush and preCompact hooks
Date Mon, 18 Dec 2017 13:00:02 GMT

    [ https://issues.apache.org/jira/browse/TEPHRA-274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16294933#comment-16294933

Ankit Singhal commented on TEPHRA-274:
--------------------------------------

[~anoopsamjohn], Tephra were creating new store scanners in preFlush and PreCompact with the
passed KeyValueScanners and passing a its own filter in the scan. As pre hooks have been updated
and now we are not getting KeyValueScanners, so is there any we can apply a filter on store
scanner before flush and compact.
I tried writing FitleredInternalScanner(attached) which is a wrapper for store scanner created
for flush and compact and applying the filter there. do you think it is a right approach or
is there any alternative?
