are you perhaps trying to send a large batch mutate? i've seen broken pipes
etc in cassandra 0.7 (currently in the process of upgrading to 1.0.8) when a
large batch mutate is sent.

Is this due to some improper load balancing?
What does nodetool ring say and what sort of queries (and RF and CL) are you
sending.

Having 10 million columns in a row is not a problem by itself. It depends on
how you want to read things.

Hi Guys,
A very trivial question on batch mutation provided by Hector. Is the execution
of the batch sequential? (in the order data is added).
Also say there are 10 operations in a batch and 3rd fails will it try the
remaining 7?
Is execution of batch mutator multi threaded ?

Hi Cassandra Users,
Heard that indexing a field with high cardinality is not good. If we create a
CF to store the index information like indexed field as key and the keys of
original CF as cols in the row. Will there be any performance improvement? Is
this the way secondary indexes are maintain
Hi Cassandra Users,
I am considering Cassandra as the main data store. Just a quick description of
the entity structure that we are looking at to store/design schema for. So we
have 3 entities A,B and C. A has one to many relationship with B and similar is
true for B and C. Hence this gives us
15 matches
