Chris Lohfink commented on CASSANDRA-7464:
------------------------------------------
> Do we need to create KSMetaData and put it into Schema?
I did at the time to prevent a NPE, but that was because I was actually using
CQL to create the cfmetadata and it looked for the reference in Schema. That
isnt necessary now though so its good to be removed.
> Do currentScanner / position need to be Atomic?
Absolutely not. Just used it as a wrapper for mutability within lambdas. I
wanted just a single ISSTableScanner so it could just have the 1 created for
both list of keys and whole sstable scans. Then the whole thing would not of
been necessary. But creating the collection of Range<Token>s for the DataRange
instead of Bounds turned into a mess (there a way of turning Bounds to Range?
overriding all the Token impls to have a inc/dec etc was intimidating).
> Replace sstable2json and json2sstable

> Both tools are pretty awful. They are primarily meant for debugging (there is
> much more efficient and convenient ways to do import/export data), but their
> output manage to be hard to handle both for humans and for tools (especially
> as soon as you have modern stuff like composites).
> There is value to having tools to export sstable contents into a format that
> is easy to manipulate by human and tools for debugging, small hacks and
> general tinkering, but sstable2json and json2sstable are not that.
> So I propose that we deprecate those tools and consider writing better
> replacements. It shouldn't be too hard to come up with an output format that
> is more aware of modern concepts like composites, UDTs, ....
