CP hooks in Scan flow for fast forward when filter filters out a row --------------------------------------------------------------------
Key: HBASE-5664 URL: https://issues.apache.org/jira/browse/HBASE-5664 Project: HBase Issue Type: Improvement Components: coprocessors Affects Versions: 0.92.1 Reporter: Anoop Sam John Fix For: 0.96.0 In HRegion.nextInternal(int limit, String metric) We have while(true) loop so as to fetch a next result which satisfies filter condition. When Filter filters out the current fetched row we call nextRow(byte [] currentRow) before going with the next row. {code} if (results.isEmpty() || filterRow()) { // this seems like a redundant step - we already consumed the row // there're no left overs. // the reasons for calling this method are: // 1. reset the filters. // 2. provide a hook to fast forward the row (used by subclasses) nextRow(currentRow); {code} // 2. provide a hook to fast forward the row (used by subclasses) We can provide same feature of fast forward support for the CP also. -- This message is automatically generated by JIRA.
