Subject [jira] [Commented] (CASSANDRA-11990) Address rows rather than partitions in SASI
Date Sat, 05 Nov 2016 03:39:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15638499#comment-15638499

Voytek Jarnot commented on CASSANDRA-11990:
-------------------------------------------

Too much of a dilettante to know, but my relatively-uneducated guess is that the fix for this
is causing CASSANDRA-12877.

> 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.),
