public static BufferSupplier create() {
        return new DefaultSupplier();
    }
Simple non-threadsafe interface for caching byte buffers. This is suitable for simple cases like ensuring that
a given KafkaConsumer reuses the same decompression buffer when iterating over fetched records. For small record
batches, allocating a potentially large buffer (64 KB for LZ4) will dominate the cost of decompressing and
iterating over the records in the batch.
