- fastest963 6y agoAnd do messages without an ordering key incur the same overhead?
- hongalex 6y agoIn the unordered case, there should be no noticeable performance degradation. This was something that we looked into extensively from both the server side as well as with our client libraries. Disclaimer: I work on Pub/Sub.
- curiousDog 6y agoStupid question, but is there an SLO/SLA around the max delay and bandwidth in the ordered case?
- longcommonname 6y agoFrom a max of 200 MB/s. To max of 1MB/s for each index.
- kamalaboulhosn 6y agoThe throughput limitation is 1MB/s per ordering key. The number of unique ordering keys allowed on a topic is limited only by what can be represented by a 1KB string, so very high throughput on a topic is still possible.
