Cbcopy Compression type

[adnanhamdussalam]

Hi,

Is it possible to set the compress-type zstd and level to 5 instead of default gzipt while using cbcopy ?
cbcopy version is v1.1.3

Hi @robertmu , could you help with this question? Thanks!

1. zstd compression is not supported. cbcopy only supports gzip and snappy
2. Setting a compression level is not possible. There is no --compress-level option

The compression behavior is fixed and automatic currently, snappy is used for COPY ON MASTER (for smaller tables). gzip is used for COPY ON SEGMENT (for larger tables). cbcopy does not provide user flags like --compress-type or --compress-level to control this behavior.
