Subject [jira] [Commented] (CASSANDRA-10232) Small optimizations in index entry serialization
Date Thu, 03 Sep 2015 15:23:46 GMT


Ariel Weisberg commented on CASSANDRA-10232:

2.2 is version c right now. 3.0 is version d. I made the change to D as part of [CASSANDRA-8684|].
Looking back I am not sure if the change actually impacted the save cache format. 

For CASSANDRA-10155 the cache format has to change. If we don't ship 3.0 with CASSANDRA-10155
saved caches will be broken with 2i. I won't change to E since I already did it to D for 3.0.

> While we should improve the data structure we use for our on-disk index in future versions,
it occurred to me that we had a few _very_ low hanging fruit optimization (as in, for 3.0)
we could do for the serialization of our current entries, like using vint encodings.
