I current use Snappy for my SSTable compression on Cassandra 1.2.8.

 

I would like to switch to using LZ4 compression for my SStables. Would simply altering the table definition mean that all newly written tables are LZ4 and can live in harmony with the existing Snappy SStables?

 

Then naturally over time more of my data will become LZ4 compressed?

Have I missed something?

 

 

Thanks,

Chris
