Subject [jira] [Commented] (CASSANDRA-5694) Allow sstable2json to dump SecondaryIndex SSTables
Date Mon, 24 Jun 2013 19:16:20 GMT


Michał Michalski commented on CASSANDRA-5694:

We have and I use it to get proper CF (the given one if it's "normal" CF or parent CF if the
given one is index CF) to "validate" input file name. I use StorageService only to instantiate
keyspace (errr... Table ;-) ) object in the begining, which I later use to getColumnFamilyStore
basing on CF name I find in filename.

> When investigating some 2I problems I had, I was pretty disappointed that sstable2json
does not allow me to dump SecondaryIndex, saying that "The provided column family is not part
of this cassandra database: keyspace = testks, column family = testcf.testcf_col_idx".
> I'm attaching patch that fixes given problem by changing a bit the way that sst2j "validates"
the input file. My only concern is that this solution uses StorageService for "validation",
so it's a bit heavier than it should, as it has to set everything up.
