- **[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. (https://github.com/ClickHouse/clickhouse-java/issues/3302)
