Matt DePero created ARROW-16983: ----------------------------------- Summary: Delta byte array encoder broken due to memory leak Key: ARROW-16983 URL: https://issues.apache.org/jira/browse/ARROW-16983 Project: Apache Arrow Issue Type: Bug Components: Go, Parquet Reporter: Matt DePero
The `DeltaByteArrayEncoder` has a memory leak due to a bug in how `EstimatedDataEncodedSize` is calculated. DeltaByteArrayEncoder extends `encoder` which calculates EstimatedDataEncodedSize by calling `Len()` on its `PooledBufferWriter` sink. DeltaByteArrayEncoder however does not write data to sink, instead writing data to `prefixEncoder` and `suffixEncoder` causing EstimatedDataEncodedSize to always return zero. -- This message was sent by Atlassian Jira (v8.20.10#820010)
