[jira] [Updated] (SPARK-25559) Just remove the unsupported
predicates in Parquet
[ https://issues.apache.org/jira/browse/SPARK-25559?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
DB Tsai updated SPARK-25559:
----------------------------
Description: Currently, in *ParquetFilters*, if one of the children predicates is not supported by Parquet, the entire predicates will be thrown away. In fact, if the unsupported predicate is in the top level *And* condition or in the child before hitting *Not* or *Or* condition, it's safe to just remove the unsupported one as unhandled filters. (was: Currently, in *ParquetFilters*, if one of the children predicate is not supported by Parquet, the entire predicates will be thrown away. In fact, if the unsupported predicate is in the top level *And* condition or in the child before hitting *Not* or *Or* condition, it's safe to just remove the unsupported one as unhandled filters.)
