> Hi @Beihao-Zhou , > > I have read your proposal and have one concern on `Secondary Keys & Values > Label Index`. The key in proposal is in `[label_key]|[label_value]|[key]` format. It may need a full iteration scan when purging a key. Making key as the first prefix part like `[key]|[label_key]|[label_value]` may reduce the complexity on cleanup. > > I'm very interested in time series topic and willing to make some contribution in this feature. 😄 > > Best Regards, Edward The secondary indexing I proposed is mainly for`MRANGE`, which will do some filtering based on label. So for this command, the secondary index is pretty similar to tag field index in KQIR (#2329). If the query asks for the TS range for a particular key, then I think searching for the primary key is enough? Let me know if I misunderstand your question. Also feel free to use any idea from the proposal! <3 -- This is an automated message from the Apache Git Service.
