> Project: Hive
> Issue Type: Bug
> Components: llap
> Affects Versions: 4.0.0, 3.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran

> Where there are too many columns (in the order of 100s), with decimal, string types the column vector pool of buffers created here [https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/io/decode/EncodedDataConsumer.java#L59] can cause memory pressure.
> Example:
> 128 (poolSize) * 300 (numCols) * 1024 (batchSize) * 80 (decimalSize) ~= 3GB
> The pool size keeps increasing when there is slow consumer but fast llap io (SSDs) leading to GC pressure when all LLAP io threads read splits from same table.
