Changeset: 5fea5dbee4bd for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=5fea5dbee4bd
Modified Files:
sql/src/backends/monet5/sql_result.mx
Branch: default
Log Message:
Set the capacity for bulk load
When you bulk load, the estimated total size is used to pre-alloc
the space, so as to avoid repeatative BATextends. In a locked mode
this should be explicitly tested and set.
