-------------------------------------------------------------------
Those knobs are actually for a slightly different index (the partition summary
itself). Though in yaml / {{Config.java}} there's {{column_index_size_in_kb}}
(defaults to 64), which I'm *pretty sure* does this, but not sure enough to
tell you to change it without testing in a lab (in particular, I don't know
exactly how it behaves if you change this with pre-existing data; I'd hope it'd
do the right thing, but I certainly haven't personally tested it, so *this is
not a recommendation* , only a pointer to a config option that exists). In
fact, CASSANDRA-5454 notes that this used to cause corruption, so I'm
definitely not saying you should do this, though it's possible that
CASSANDRA-5454 makes this safe to do.
(FWIW, on the index summary, we downsample if we get over 2GB - see
CASSANDRA-12014 - and I think instead of changing this to a long, we should
consider that here as well, until CASSANDRA-9754 is done, which makes this a
moot point).
[~krummas] / [~bdeggleston] , what do you guys think about the safety of this,
especially re: streaming?

> URL: https://issues.apache.org/jira/browse/CASSANDRA-13973
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Reporter: Dan Kinder
>
> After an upgrade from 2.2.6 to 3.0.15 (sstable version la to mc), when I try
> to run upgradesstables, most of them upgrade fine but I see the exception
> below on several nodes, and it doesn't complete.
> CASSANDRA-12717 looks similar but the stack trace is not the same, so I
> assumed it is not identical. The various nodes this happens on all give the
> same trace.
> Might be notable that this is an analytics cluster with some large
> partitions, in the GB size.
