From 06bde1d923d592e485fae19df4014c007136e6d2 Mon Sep 17 00:00:00 2001 From: Jimmy Lu Date: Mon, 16 Sep 2024 11:46:10 -0700 Subject: [PATCH] Parquet LazyVector support (#11010) Summary: Pull Request resolved: https://github.com/facebookincubator/velox/pull/11010 Parquet reader was not generating `LazyVector` at all. Fix this and address the bugs along the way: 1. Fix the `rowIndex` passed to hook by considering `numValuesBias_`. 2. Add the missing `setNumValues` call in Parquet `StringDecoder`. 3. Fix the Parquet string dictionary column visitor call and reuse the same code in DWRF string dictionary column reader. 4. Fix write over boundary in `VectorLoader::load`.
