Subject [jira] [Commented] (CASSANDRA-11990) Address rows rather than partitions in SASI
Date Fri, 22 Jul 2016 11:18:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15389335#comment-15389335

Alex Petrov commented on CASSANDRA-11990:
-----------------------------------------

Please note that support for reading from old version before sstables were fully upgraded
is still tbd in the branch. If everything else is settled, I'll add the backward-compatible
version, which should be quite simple (mostly changing the size of RowOffset and reading an
entire partition for that case).

> Currently, the lookup in SASI index would return the key position of the partition. After
the partition lookup, the rows are iterated and the operators are applied in order to filter
out ones that do not match.
> bq. TokenTree which accepts variable size keys (such would enable different partitioners,
collections support, primary key indexing etc.),
