Uwe L. Korn created PARQUET-1392: ------------------------------------ Summary: [C++] Supply row group indices to parquet::arrow::FileReader::ReadTable Key: PARQUET-1392 URL: https://issues.apache.org/jira/browse/PARQUET-1392 Project: Parquet Issue Type: New Feature Components: parquet-cpp Reporter: Uwe L. Korn Assignee: Uwe L. Korn Fix For: cpp-1.5.0
By looking at the Parquet statistics, a user can already determine with its own logic which RowGroups are interesting for him. Currently we only provide functions to read the whole file or individual RowGroups. By supplying {{parquet::arrow}} with the RowGroups at once, it can better optimize its memory allocations as well as make better use of the underlying thread pool. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
