Hello,
I have a question about CQL memory usage. I am currently using 1.2.9.
If I have a Cassandra table like this (created using Astyanax API):
CREATE TABLE table_name (
key text,
column1 text,
value blob,
PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE;
and I run a query like this:
You have millions of org.apache.cassandra.db.DeletedColumn instances on the
snapshot.
This means you have lots of column tombstones, and I guess, which are read
into memory by slice query.

Hi, experts,
Since the Cassandra 2.x supports DB that across multiple DCs, my question is
how many DCs can Cassandra support in practice?

Hi, experts,
I need to query all columns of a row in a column family that meet some
conditions (see below). The column is composite column and has following
format:
... where componentN has String type.
What I want to do is to find out all columns that meet following conditions:
1. comp
I am trying to understand why one of my nodes keeps full GC.
I have Xmx set to 8gigs, memtable total size is 2 gigs.
