Basic tests added, but more cases might be desirable.\r\n\r\nNote that this is just a first pass; the final implementation will likely be something like an expression that is evaluated by a generic multi-row-output apply operator. Also multi-column splits are possible (where we would take cartesian product of all results).\r\n"},"comment":{"url":"https://api.github.com/repos/uwescience/myria/issues/comments/83272073","html_url":"https://github.com/uwescience/myria/pull/722#issuecomment-83272073","issue_url":"https://api.github.com/repos/uwescience/myria/issues/722","id":83272073,"user":{"login":"senderista","id":131425,"avatar_url":"https://avatars.githubusercontent.com/u/131425?v=3","gravatar_id":"","url":"https://api.github.com/users/senderista","html_url":"https://github.com/senderista","followers_url":"https://api.github.com/users/senderista/followers","following_url":"https://api.github.com/users/senderista/following{/other_user}","gists_url":"https://api.github.com/users/senderista/gists{/gist_id}","starred_url":"https://api.github.com/users/senderista/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/senderista/subscriptions","organizations_url":"https://api.github.com/users/senderista/orgs","repos_url":"https://api.github.com/users/senderista/repos","events_url":"https://api.github.com/users/senderista/events{/privacy}","received_events_url":"https://api.github.com/users/senderista/received_events","type":"User","site_admin":false},"created_at":"2015-03-19T02:40:19Z","updated_at":"2015-03-19T02:40:19Z","body":"edu.washington.escience.myria.systemtest.JsonQuerySubmitTest.ingestTest is failing for reasons unrelated to this PR"}}
