liuxian created SPARK-24994: ------------------------------- Summary: When the data type of the field is converted to other types, it can also support pushdown to parquet Key: SPARK-24994 URL: https://issues.apache.org/jira/browse/SPARK-24994 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.4.0 Reporter: liuxian
For this statement: select * from table1 where a = 100; the data type of `a` is `smallint` , because the defaut data type of 100 is `int` ,so the data type of 'a' is converted to `int`. In this case, it does not support push down to parquet. In our business, for our SQL statements, and we generally do not convert 100 to `smallint`, We hope that it can support push down to parquet for this situation. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
