ATTACHMENT ID: 12731561 - PreCommit-HIVE-TRUNK-Build > Support limited integer type promotion in ORC > --------------------------------------------- > > Key: HIVE-10591 > URL: https://issues.apache.org/jira/browse/HIVE-10591 > Project: Hive > Issue Type: New Feature > Affects Versions: 1.3.0 > Reporter: Prasanth Jayachandran > Assignee: Prasanth Jayachandran > Attachments: HIVE-10591.1.patch, HIVE-10591.2.patch, > HIVE-10591.2.patch, HIVE-10591.3.patch, HIVE-10591.3.patch, HIVE-10591.3.patch > > > ORC currently does not support schema-on-read. If we alter an ORC table with > 'int' type to 'bigint' and if we query the altered table ClassCastException > will be thrown as the schema on read from table descriptor will expect > LongWritable whereas ORC will return IntWritable based on file schema stored > within ORC file. OrcSerde currently doesn't do any type conversions or type > promotions for performance reasons in inner loop. Since smallints, ints and > bigints are stored in the same way in ORC, it will be possible be allow such > type promotions without hurting performance. Following type promotions can be > supported without any casting > smallint -> int > smallint -> bigint > int -> bigint > Tinyint promotion is not possible without casting as tinyints are stored > using RLE byte writer whereas smallints, ints and bigints are stored using > RLE integer writer. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
