### What is the problem the feature request solves? Native shuffle currently encodes the name of the compression codec and the IPC schema once per batch. Storing the schema per batch was originally a requirement because the schema could vary between batches due to dictionary encoding but this is no longer the case. ### Describe the potential solution Write the compression codec name and schema once per partittion. This can be implemented in `ShuffleBlockWriter::try_new`. Update `ShuffleBlockWriter::write_batch` to no longer write the header per batch. Make correspondong changes in the reader `NativeBlockDecoderIterator.scala`. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
