Subject How Spark Calculate partition size automatically
Date Mon, 12 Jan 2015 22:33:23 GMT
Hi,

When I am running a job, that is loading the data from Cassandra, Spark has
created almost 9million partitions. How spark decide the partition count? I
have read from one of the presentation that it is good to have 1000 to
10,000 partitions.

Regards
Raj
