Return buffers to the pool after executing prepared INSERT statement, so they can be reused again even if statement is not closed Co-authored-by: Andrey Nudko <andrey.nudko>
…eBinary() overrides. (#396) Instead of copying serialized column data from ByteBuffer via intermediate byte[], just write backing array directly. This somewhat couples ColumnWriterBuffer with ByteArrayWriter internals, however as the name implies ByteArrayWriter is expected to use heap buffers (and using direct buffers for block data wouldn't make much sense now anyway - I/O layer is operating on byte[], plus most JVMs impose limits on direct memory allocation). ByteArrayWriter and CompressedBuffedWriter use fixed-size buffers internally and chunk bytes already. SocketBuffedWriter may benefit from splitting large writes into smaller ones to minimize malloc/free in native code - but it shouldn't be worse than current situation (at least with compression) and likely to be dubious optimisation.
