The best practices for Storm/Cassandra
applications
When working with distributed applications that have SLAs operating 24/7 with a very
high velocity and a miniscule average processing time, certain aspects become extremely
crucial to be taken care of:
• Network latency plays a big role in real-time applications and can make or break
products, so make a very informed and conscious decision on the placement of
various nodes in a data center or across data centers. In such situations, it's gener-
ally advisable to keep ping latency at a minimum.
• The replication factor should be around three for Cassandra.
• Compaction should be part of routine Cassandra maintenance.
