add -tune micro/small/medium/large/huge flag #21
Description
Similar to how mysql ships my.cnf-huge etc. add a flag that gets different presets in cassandra.yaml and the sprokfile. micro should be tuned for Raspberry Pi. Huge should be G1 and 32+GB RAM. etc. On startup of a node the user can specify and get a reasonably good starting place for tuning:
docker run -d --net=host -v /data tobert/cassandra -tune standard -name "my std cluster"
Might make sense to add some cloud instance presets too, such as "i2.xlarge" etc.?
First pass:
Add sproks with the JVM flags in them named cassandra-preset-small.yaml etc.. The entrypoint will copy the correct file. The presets for cassandra.yaml might go in another yaml chunk rather than copying whole files around. Goal: keep it easy to review what's different across the sizes.
