clickhouse-java v0.11.1

Bug Fixes

• [client-v2] Fixed INSERT failing with LZ4Exception: maxDestLen is too small (LZ4) or ZstdException: Destination buffer is too small (ZSTD) when request compression is enabled (compressClientRequest(true)) and a 64 KiB block of the data does not compress, for example random bytes. The compressed output buffer was as large as the uncompressed block, but such a block grows when it is compressed. The buffer is now sized with the worst-case bound of the codec (LZ4Compressor.maxCompressedLength, Zstd.compressBound). The bug was introduced in 0.11.0.
