Hi all,
I'm almost sure I'm just tired and I am doing something stupid however I can't
understand this problem.
In one Super Column Family I have just 2 rows, called ALL and INCREMENTAL.
For some reason I sometimes need to duplicate a SuperColumn from the row ALL
to the INCREMENTAL one ... very easy
(cassandra 0.7.4, java, pelops)
private static void mirrorizeEngineSuperColumn(Bytes superColumnId) {
Mutator mutator = Pelops.createMutator(SocialContext.POOL_NAME_VALUE);
Selector selector = Pelops.createSelector(SocialContext.
POOL_NAME_VALUE);
try {
SuperColumn sc = selector.getSuperColumnFromRow(MotoreFamily,
SocialColumn.MOTORE_ALL_ROW, superColumnId, ConsistencyLevel.QUORUM);
LOG.debug("Column list size of supercolumn is " + sc.
getColumnsSize());
mutator.writeSubColumns(MotoreFamily, SocialColumn.
MOTORE_INCREMENTALI_ROW, superColumnId, sc.getColumns());
mutator.execute(ConsistencyLevel.QUORUM);
} catch (NotFoundException nfe) {
LOG.debug("Supercolumn not found ...");
} catch (Exception e) {
LOG.error(e.toString());
}
}
When I print it the column list size is exact (3, 4 it depends on which
supercolumn I'm working) but when I write them I find only one column of this
column list ... here is the output produced (viewing with cassandra cli ...) --
compare the 3 super_column in the row INCREMENTAL and you'll see they're
different from the one in the row ALL

TIA for any help
