-----------------------------------------
Summary: CQL should be able to do a delete with a > or < operator
on a clustering portion of a primary key
Key: CASSANDRA-6292
URL: https://issues.apache.org/jira/browse/CASSANDRA-6292
Project: Cassandra
Issue Type: Improvement
Components: API
Reporter: Tupshin Harper
Assignee: Jonathan Ellis
Fix For: 2.1
The following creates a table that at the storage engine level, has "key" as
the row key, and evt as a time ordered list of columns within the row:
create table test (key text, evt timestamp, primary key(key,evt)) with
clustering order by (evt asc);
Given the ability to create slice tombstones (both implicitly by deleting
collections and supercolumns) as well as in thrift through a delete with a
slice predicate.
Given the schema above, the expected syntax to delete all columns with key
"one" and timestamp less than 1000 would be:
delete from test where key='one' and evt < 1000;
and if you did that as well as
delete from test where key='one' and evt > 1000;
You would accomplish exactly what is being asked about (in terms of thrift and
astyanax) here:
