Pavan Lanka created ORC-758:
-------------------------------
Summary: Avoid decompressing compressed streams if already
decompressed
Key: ORC-758
URL: https://issues.apache.org/jira/browse/ORC-758
Project: ORC
Issue Type: Sub-task
Components: Java
Affects Versions: 1.7.0
Reporter: Pavan Lanka
Assignee: Pavan Lanka
The current behavior of `InStream.CompressedStream` does not avoid seek and
decompression if the required position is already decompressed and available.
This results in multiple decompressions of the same compression blocks. This
can be avoided by tracking the current position and avoid decompression if we
are at the required position already.
