Subject [jira] [Updated] (CASSANDRA-3749) Allow rangeSlice queries to be start/end inclusive/exclusive
Date Wed, 18 Jan 2012 22:06:41 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3749?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-3749:
--------------------------------------

    Attachment: 3749-comments.txt

Even after updating the comments to make things a bit more clear (attached), I'm still confused
by the remainder/split dance.  For instance, if we are splitting a Bounds on bounds.right,
that means that remainder overlaps Bounds entirely and so we should add that to the ranges,
but instead we skip it.

> Currently, given two keys k1 and k2, we can only do a rangeSlice on the intervals (k1,
k2] (Range) and [k1, k2] (Bounds). CQL goes around this "manually", by querying one more row
if the start is exclusive and removing the start/end post-query if necessary. This doesn't
work however with the new option introduced by CASSANDRA-3742. So this ticket proposes to
add support (internally) for doing a rangeSlice for the intervals (k1, k2) an [k1, k2).
