a quorum write is not the same as actually doing one.

looked into it too much, but I
think forcing a major compaction when using leveled strategy doesn't have
the same effect as with size tiered.

Probably more efficient but generally page numbers go backwards ie page 1
has newest content so this would complicate things when writing data and
cause load if logic was included to reorganise page numbers etc.

As for why I'd want such a thing, I just wanted to initialize some test
values for a blob column with cqlsh.
Thanks!

finishes. We only have one CF and
right now the number of SSTable is around 15000, write latency is still
under 0.1ms.
Anything needs to be concerned? Or anything I can do to reduce the number
of pending compaction?
Thanks.

For now, we had ot add all nodes ot the seeds list instead so it
distributes amongst all nodes.

I could be wrong about this, but when repair is run, it isn't just values

Can we force somehow cassandra not to lookup keys in remote CD?
Thanks for your answers!

in Cassandra and the table in MySQL,and I
find the processing time of MySQL is better than Cassandra.
So,I wander what are the advantages of Cassandra compare MySQL and how to
improve the performance of Cassandra.
Is this the right way to use Cassandra.

My only other wishlist item is the ability to set the timestamp, ttl, and

partitioner to store the rows in order, but that is not
recommended because you wont get even distribution throughout our cluster.
I think your best bet though is just use the master_id for your row key,
and then use composite columns that begin with the client_id.

You can have a dynamic table with CQL3, you just can't have a table with a
mix of dynamic/nondynamic columns.

even more rows; I wanted wide rows so the reads and writes would be more

To clarify, I haven't tested it with compact storage, but it will only use
the first part of the primary key without compact storage.

Actually, my solution only makes a row for each unique value of the first

just contains server classes. Everything you need

To use cql3 I just use the client methods 'execute_cql_query',
'prepare_cql_query' and 'execute_prepared_cql_query', after setting cql
version to '3.0.0'.
