Renato Javier Marroquín Mogrovejo updated GORA-154:
---------------------------------------------------
Attachment: GORA-154.v2.patch
Hi all,
This is a second version of this patch. The first one was done by Lewis and I
have been able to improve it (:
There are some problems while doing deletes in Cassandra, and that is the use
of Tombstones which mean that the actual key will remain inside the data store
until a majorCompaction is done and certain period of time passes
(gc_grace_seconds and TTL time metric). So this means that the key will
actually stay there until someone triggers this actions from outside GoraLand.
If someone could review this, it'd be awesome!
> delete() and deleteByQuery() methods are not implemented at CassandraStore,
> and always returns false or 0

> CassandraStore.java has the followings:
> @Override
> public boolean delete(K key) throws IOException {
> LOG.debug("delete " + key);
> return false;
> }
> @Override
> public long deleteByQuery(Query<K, T> query) throws IOException {
