Brandon Williams commented on CASSANDRA-3264: --------------------------------------------- bq. To clarify: I'm saying CFIF should allow specifying a CQL query, alongside the existing SlicePredicate API. Then we solve this problem for "free" when CASSANDRA-2474 is done. +1 to that, then, I only suggested not waiting for CASSANDRA-2474 when this was seemingly more urgent than it is now. > 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 > Labels: lhf > Fix For: 1.0.2 > > > 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.
