Since current getting schema for CapnProto doesn't use cache, the integration test was for the future if someone add cache. Also, I was curious how schema cache affects performance and I compared reading binary files with Protobuf (I guess it works the same for CapnProto). ``` for i in {1..1000}; do clickhouse-client -q \ "select * from test.simple format Protobuf settings format_schema='/format_schemas/simple:KeyValuePair'" > simple-protobuf${i}.bin; done clickhouse-client --time -q "select * from file('simple-protobuf{1..999}.bin', 'Protobuf') format Null settings format_schema = 'simple:KeyValuePair'" ``` Protobuf with cache and without works with approximately the same time. |
