In-Depth Information
The suggested size of data per machine closely depends on an application's read and write
load. However, in general, keeping the data size of per machine to 1 TB or below is a
good idea, although Cassandra can work decently well up to 5 TB of data per node.
Network
As any other distributed system, Cassandra is highly dependent on the network. Although
Cassandra is tolerant to network partitioning, a reliable network with less outages is pre-
ferred for the system—less repairs and less inconsistencies.
A congestion-free, high-speed (gigabit or higher), reliable network is pretty important as
each read-write, replication, and moving and/or draining node puts heavy load on the net-
work.
