Indexes are stored locally to data node.
•
Updates to column values are indexes, which is an atomic operation.
•
Avoid secondary indexes over high cardinality column values.
•
Too many indexes can kill write performance and should be avoided. In-
stead try to denormalize the data model, or use composite columns.
With data modeling in place, the next question while designing an application with
Cassandra that naturally comes to mind is data security.
Chapter 4
will talk about data
encryption/decryption and the security options available with Cassandra.
