------------------------------------
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.
