[GitHub] [doris] AshinGau opened a new pull request, #11237: [feature-wip](multi-catalog)(fix) partition value error when a block contains multiple splits.
AshinGau opened a new pull request, #11237:
URL: https://github.com/apache/doris/pull/11237
# Proposed changes
`FileArrowScanner::get_next` returns a block when full, so it maybe contains multiple splits in small files or crosses two splits in large files. However, a block can only fill the partition values from one file. Different splits may be from different files, causing the error of embed partition values. so we should return the block when reading at the `EOF` of a split.
