Use case

Our Iceberg catalog provider enables compression of the manifest.json file by default. The current Clickhouse Iceberg integration makes it impossible to open this file.

Describe the solution you'd like

Clickhouse can read compressed Iceberg manifest files where write.metadata.compression-codec = gzip is set on the table.

Describe alternatives you've considered

A workaround is to disable the compression of the manifest file by setting write.metadata.compression-codec = none
