stack commented on HBASE-11811: ------------------------------- Patch looks good. Would help case where repeated, random seeks in a small set of hot blocks. Won't help scans. We should write the index into the block at write time rather than calculate when reading? > Use binary search for seeking into a block > ------------------------------------------ > > Key: HBASE-11811 > URL: https://issues.apache.org/jira/browse/HBASE-11811 > Project: HBase > Issue Type: Brainstorming > Reporter: Lars Hofhansl > Attachments: 11811-wip-v2.txt, 11811-wip-v4.txt, block_index-v2.txt > > > Currently upon every seek (including Gets) we need to linearly look through > the block from the beginning until we find the Cell we are looking for. > It should be possible to build a simple cache of offsets of Cells for each > block as it is loaded and then use binary search to find the Cell in question. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
