Summary: [C++] Implement block-based buffer to replace DataBuffer
in the ColumnWriter
Key: ORC-1280
URL: https://issues.apache.org/jira/browse/ORC-1280
Project: ORC
Issue Type: Improvement
Components: C++
Reporter: Gang Wu
Assignee: ZhangXin
The problem comes from a community discussion: [Huge memory taken for each
field when exporting · Issue #1240 · apache/orc
(github.com)|https://github.com/apache/orc/issues/1240]. The basic idea is to
implement a block-based buffer management and replace the DataBuffer within the
ColumnWriter to automatically adapt its size to accommodate data before
compression.
