Kenneth Knowles resolved BEAM-6810. ----------------------------------- Resolution: Fixed > [SQL] Plan optimizer eliminates aliasing in trivial projections > --------------------------------------------------------------- > > Key: BEAM-6810 > URL: https://issues.apache.org/jira/browse/BEAM-6810 > Project: Beam > Issue Type: Bug > Components: dsl-sql > Affects Versions: 2.11.0 > Reporter: Gleb Kanterov > Assignee: Gleb Kanterov > Priority: Major > Fix For: 2.12.0 > > Time Spent: 50m > Remaining Estimate: 0h > > Trivial programs project precisely their input fields, without dropping or > re-ordering them. The simplest example is: > {code} > SELECT * FROM PCOLLECTION > {code} > Given input PCollection with a schema `c_int64: BIGINT` following query > should result in PCollection with a schema `abc: BIGINT`, however, due to a > bug in query optimization, it results in `c_int64: BIGINT` > {code} > SELECT c_int64 as abc FROM PCOLLECTION > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
