Jonathan Ellis commented on CASSANDRA-3264: ------------------------------------------- I think it makes a bit more sense to just skip the int columns instead of turning them into Strings, but either way, +1. > Add wide row paging for ColumnFamilyInputFormat and ColumnFamilyOutputFormat > ---------------------------------------------------------------------------- > > Key: CASSANDRA-3264 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3264 > Project: Cassandra > Issue Type: Improvement > Components: Hadoop > Reporter: T Jake Luciani > Assignee: Jonathan Ellis > Labels: hadoop > Fix For: 1.1 > > > Hadoop input/output formats currently can OOM on wide rows. > We can add a new option to the ConfigHelper like columnPagingSize with a > default of Integer.MAX_VALUE. > The input format would page the row internally rather than pull it over at > once. > The output format could also use this to avoid sending huge rows over at once. -- This message is automatically generated by JIRA.
