> URL: https://issues.apache.org/jira/browse/HIVE-11611
> Project: Hive
> Issue Type: Sub-task
> Affects Versions: 2.0.0
> Reporter: Sergio Peña
> Assignee: Ferdinand Xu
> Attachments: HIVE-11611.patch

>
> A possible performance issue may happen with the below code when using a
> query like this {{SELECT count(1) FROM parquetTable}}.
> {code}
> if (!ColumnProjectionUtils.isReadAllColumns(configuration) &&
> !indexColumnsWanted.isEmpty()) {
> MessageType requestedSchemaByUser =
> getSchemaByIndex(tableSchema, columnNamesList,
> indexColumnsWanted);
> return new ReadContext(requestedSchemaByUser, contextMetadata);
> } else {
> return new ReadContext(tableSchema, contextMetadata);
> }
> {code}
> If there are not columns nor indexes selected, then the above code will read
> the full schema from Parquet even if Hive does not do anything with such
> values.
