Subject [jira] [Commented] (CASSANDRA-9618) Consider deprecating sstable2json/json2sstable in 2.2
Date Thu, 18 Jun 2015 20:33:01 GMT


Jonathan Ellis commented on CASSANDRA-9618:

How is 7464 not just sstable2json with a different output format?

(We've changed output format dramatically before, it's totally valid to do that in a major

> The rational is explained in CASSANDRA-7464 but to rephrase a bit:
> * json2sstable is pretty much useless, {{CQLSSTableWriter}} is way more flexible if you
need to write sstable directly.
> * sstable2json is really only potentially useful for debugging, but it's pretty bad at
that (it's output is not really all that helpul in modern Cassandra in particular).
> Now, it happens that updating those tool for CASSANDRA-8099, while possible, is a bit
involved. So I don't think it make sense to invest effort in maintain these tools. So I propose
to deprecate these in 2.2 with removal in 3.0.
> I'll note that having a tool to help debugging sstable can be useful, but I propose to
add a tool for that purpose with CASSANDRA-7464.
