[GitHub] [samza] atoomula opened a new pull request #1154: SAMZA-2321: Samza-sql - Introduce REAL Samza sql schema type

atoomula opened a new pull request #1154: SAMZA-2321: Samza-sql - Introduce REAL Samza sql schema type
URL: https://github.com/apache/samza/pull/1154
 
 
   In Sql, REAL is 4-bytes while FLOAT and DOUBLE are both 8-bytes. While in Java and Avro, FLOAT is 4-bytes and DOUBLE is 8-bytes.
   
   Fix the discrepancy in Samza Sql code by introducing REAL Samza Sql schema type and do the right mapping in AvroTypeFactoryImpl and RelSchemaConverter. Changes made earlier in AvroRelConverter are reverted.
   
   Equivalent change in Calcite was made as part of this ticket: https://issues.apache.org/jira/browse/CALCITE-638
