T Jake Luciani commented on CASSANDRA-3264: ------------------------------------------- This isn't a transpose! This is paging.... Maybe an example will help... if you set column.paging.size = 3 RowA => [col1, col2, col3,..., colN] Would become: RowA => [col1, col2, col3] RowA => [col4, col5, col6] RowA => [col7, col8, col9] > 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.
