Subject [jira] [Updated] (HBASE-12077) FilterLists create many ArrayList$Itr object per row.
Date Wed, 24 Sep 2014 06:35:35 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12077?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lars Hofhansl updated HBASE-12077:
----------------------------------
    Description: Almost all methods in FilterList do work on behalf the passes list of filters,
which - you guessed it - is always an ArrayList and we always iterate over those with an iterator.
Multiple of these methods are called to each row leading to creating about 10 Itr for single
row touched (whether filtered or not)
