This doesn't reproduce with the steps you're providing. There's clearly some
pre-existing data in the table, and some sort of operation on that table in the
past that isn't evident from your repro steps.

The easiest way to do this is to create another Cassandra DC and point
Spark to it, since Spark can operate directly on data in Cassandra. No
impact on C* performance and no complex backup/restore process required,
just let Cassandra replicate the data for you.
If you need a scalable bulk export/i
Its the number of sstables that may of been read from. This includes
sstables who had their bloom filters checked (which may hit disk). This
changes a bit in https://issues.apache.org/jira/browse/CASSANDRA-13120 to
be only the sstables that its actually reading from.

I have a scenario where data has to be loaded into Spark nodes from two data
stores: Oracle and Cassandra. We did the initial loading of data and found a
way to do daily incremental loading from Oracle to Spark.
I’m tying to figure our how to do this from C*. What tools are available in C*

Hello Apache Cassandra Community,
Solutions.Hamburg is offering Apache conference speaking slots, and
some time to advertise for the ASF. We were wondering if anyone in
the Cassandra community would like to give a technical talk on Apache
Cassandra, between September 6-8 in Hamburg.
