Tuning validations
Configure validation rate to meet target deadlines.
system.log
The location of the system.log file is:- /var/log/cassandra/system.log
NodeSync tries to validate all tables within their respective deadlines, while respecting the
configured rate limit. If a table is 10GB and has a deadline_target_sec=10
and
the rate_in_kb is set to 1MB/sec, validation will
not happen quickly enough. Configure the rate and deadlines realistically, take data sizes
into account and adapt with data growth.
- rate_in_kb is too low to validate all tables within their deadline, even under ideal circumstances.
- rate_in_kb cannot be sustained by the node (too high for the node load/hardware).
