What is the maximum size/number of lines of cassandra cqlsh_history and cli.history?

Question

I am using cassandra version 2.1.16. I have verfied that the cli.history files contains max 501 lines. However I dont see there is a limit for cqlsh_history file. Any idea on that.

Answer 1

cqlsh uses the readline Python module, and does not set a history length. By default, readline does not limit the history file.

This assumes you're using CPython 2.7. If you have a different interpreter, you can examine the default using

python -c "import readline; print readline.get_history_length()"
