> There is a potential performance improvement here. We could create a Deflater/Inflater pair per column family. This idea didn't pan out. It makes compression in my test case slightly worse. Let me collect some microbenchmarks for the Deflate compression level options of DEFAULT, BEST_SPEED, and BEST_COMPRESSION with the latest code and present them here. Basically, BEST_COMPRESSION is twice as slow on average as DEFAULT for marginal gains, and BEST_COMPRESSION is twice as fast as DEFAULT but does not compress as well, but good enough, and speed counts here, so BEST_SPEED is best. (However I collected these measures with dictionary per cf so need to redo now that I've dropped the idea.) -- This is an automated message from the Apache Git Service.
