It's a mix in 0.6 unfortunately. For 0.7 all have been converted to blocking.

Ok, cool. I thought all the nodetool commands were non blocking.

Hi Jonathan,
I don't suppose there's any plan to support subcolumns of supercolumns in
secondary indexes in the future ?

And I'm still getting UnavailableException and TimedOutException when there
Cassandra daemon is doing either Compaction or Garbage collection...

No, additional expressions (the GTE here) only affect what rows come
back and do not affect sort order.

OK,
I have a query with 2 expressions:
1st: with GTE operator
2nd: with EQ operator
both columns are indexed, but results are sorted in token order (I should
expect to be sorted by 1st expression column values).
Am I correct?

secondary index results are always sorted by indexed column value.
rows with the same index value are sorted in token order (although
support for comparator order is planned).
sorting by a different column is not possible to do efficiently
server-side and therefore is left to the client.
On Fri,
Hi,
is it possible to sort results based on secondary index search?
Typical use case is to get most recent comments from specified group
CF: comments
* SI: group
* SI: timestamp
I've asked before, but I can't still found any information.
Thanks

I new to Cassandra. I know it is not relational database and it is
NoSQL. Is there any ODBC/JDBC driver for Cassandra?
I cam through the same problem. I have set the end key same as start key, it
worked. (Kinda temp fix...)

this looks like compaction is OOMing while processing a large row.

Hi,
I have CF User with secondary index on "email" column.
When I remove a whole row,
del User['row']
SI is not updated and get_indexed_slices still returns the deleted data.
Is it still open bug?
Using latest nightly build.

Hi,
I've managed to get secondary indexes working on Normal Columns. I've even
managed to get multiple IndexExpressions to work when querying.
However, its not clear to me
1) If I should be able to have a secondary index on a sub-column of a
super-column
2) Assuming 1 is supported, how to speci
