Branimir Lambov commented on CASSANDRA-18398:
---------------------------------------------

bq. This is more venting than constructive feedback, but there are certainly 
parts of this patch that would be simpler without early open in play. Are there 
any active proposals to remove it for 5.0?

At this point there is little hope to achieve what early open does without it.

bq. RE checksumming on the partition/row index files, would a reasonable path 
forward for now be to spin off a separate Jira where we look into at least 
verifying integrity on startup (and streaming?), sort of like what we do w/ 
DIGEST?

Let's make it a separate JIRA; this can be done post 5.0. If it is a startup 
check (which may have the side effect of warming up the cache for indexes), the 
CRCs can be in a different file. If not, they need to be stored with the page 
to avoid costly additional page fetches.
