Summary
Adds connection-level block compression to the MATLAB client, exposed through a type-safe Compression enum and wired through to clickhouse-cpp's ClientOptions::SetCompressionMethod. The native TCP
client supports three methods — None / LZ4 / ZSTD — and the connection now defaults to LZ4.
opts = struct('compression', Compression.ZSTD); % or .LZ4 (default) / .None
c = ClickHouseClient('localhost', 9000, 'default', '', opts);
The connection now uses LZ4 by default (previously no compression).
Existing callers that omit options.compression will start compressing on the wire after upgrading. Pass options.compression =
Compression.None to restore the old behavior.
