Benjamin Lerer commented on CASSANDRA-7461: ------------------------------------------- {quote} Do you think there is that much difference between those to justify spitting it? {quote} I asked myself that question. On the java side I do not think it is the case but each type of operators need to be tested and documented. Some changes needs also to be done to {{CQLSH}} for auto completion. In the end I came to the conclusion that splitting the ticket will reduce the risk of forgetting stuff and make the review process easier but I might be wrong. {quote} it's that part that I would split in a separate ticket (since again, it's not specific to operators, even if operators are a good motivation for the improvement). {quote} It is definetly something that we should do. > operator functionality in CQL > ----------------------------- > > Key: CASSANDRA-7461 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7461 > Project: Cassandra > Issue Type: New Feature > Components: CQL > Reporter: Robert Stupp > Assignee: Benjamin Lerer > Labels: cql > > Intention: Allow operators in CQL > Operators could be decimal arithmetics {{+ - * /}} or boolen arithmetics {{| > & !}} or string 'arithmetics' {{+}} > {{SELECT tab.label + ' = ' + tab.value FROM foo.tab}} > {{SELECT * FROM tab WHERE tab.label + ' = ' + tab.value = 'foo = bar'}} > as well as > {{CREATE INDEX idx ON tab ( tab.tabel + '=' + tab.value )}} > or > {{CREATE INDEX idx ON tab (label) WHERE contains(tab.tabel, > 'very-important-key')}} > Operators could be mapped to UDFs like this: > {{+}} mapped to UDF {{cstarstd::oper_plus(...)}} > {{-}} mapped to UDF {{cstarstd::oper_minus(...)}} > or handled directly via {{Cql.g}} in 'special' code -- This message was sent by Atlassian JIRA (v6.3.4#6332)
