1 year ago What about the average traffic usage difference? It's hard to tell what's happening just from usage graphs. I'm 99% sure that compression works because with --grpc-compression=snappy my project https://github.com/GiedriusS/thanos-rust doesn't work (https://github.com/hyperium/tonic/issues/282):
Error executing query: proxy Series(): rpc error: code = Aborted desc = receive series from Addr: 127.0.0.1:50051 LabelSets: {dc="hx", prometheus_node_id="5"} Mint: -9223372036854775808 Maxt: 9223372036854775807: rpc error: code = Unimplemented desc = Message compressed, compression support not enabled.Perhaps your traffic consists of a lot of unique labels or you have lots of different, small queries hence there's no obvious effect.

Version:
Thanos: v0.29.0-rc.0 Image: thanosio/thanos:v0.29.0-rc.0
What happened:
I did a grpc compression test with the latest version of the image, trying to reduce the transmission traffic.
Data flow diagram:
store(grpc) -> query1(grpc) -> query2(http) -> queryFrontendquery1 traffic map: yellow: with
--grpc-compression=snappygreen: with--grpc-compression=nonequery2 traffic map: yellow: with
--grpc-compression=snappygreen: with--grpc-compression=none**What you expected to happen:
The bandwidth in query1 & query2 should be reduced after turning on grpc compression.
