Subject [jira] [Commented] (CASSANDRA-10990) Support streaming of older version sstables in 3.0
Date Fri, 19 Feb 2016 19:05:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15154677#comment-15154677

Yuki Morishita commented on CASSANDRA-10990:
--------------------------------------------

One more suggestion.
Isn't it simpler to just have CachedInputStream that first fills on heap buffer and writes
out to file as buffer gets full?

bq. Do you easily remember if there is a way to retrieve the average partition size for a
given table? I remember seeing something along those lines but I'm not sure where it is.

I think we can just set to be more sane value (few hundreds kilobytes?), the use case here
is for static columns only.

> In 2.0 we introduced support for streaming older versioned sstables (CASSANDRA-5772).
 In 3.0, because of the rewrite of the storage layer, this became no longer supported.  So
currently, while 3.0 can read sstables in the 2.1/2.2 format, it cannot stream the older versioned
sstables.  We should do some work to make this still possible to be consistent with what CASSANDRA-5772
provided.
