> 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.
