Subject [jira] [Comment Edited] (CASSANDRA-12367) Add an API to request the size of a CQL partition
Date Tue, 23 Aug 2016 07:32:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15432280#comment-15432280

----------------------------------------------------------------------

Could we use {{SSTableReader.getScanner(Range<Token> range, ...)}} instead of scanning
all the partitions in the sstable? We would need to create the range so that it includes the
token requested but I think it should save us some time by seeking to the correct position
directly.

edit: And maybe we should output more information about the partition? Like average row size,
number of rows, tombstones, etc?

> It would be useful to have an API that we could use to get the total serialized size
of a CQL partition, scoped by keyspace and table, on disk.
