[jira] [Updated] (HBASE-9000) Linear reseek in Memstore

     [ https://issues.apache.org/jira/browse/HBASE-9000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shane Hogan updated HBASE-9000:
-------------------------------

    Description: This is to address the linear reseek in MemStoreScanner. Currently reseek iterates over the kvset and the snapshot linearly by just calling next repeatedly. The new solution is to do this linear seek up to a configurable maximum amount of time then if the seek is not yet complete fall back to logarithmic seek.
