----------------------------------------
Hi [~hxd],
Sorry for the late reply - I was caught up in exams and assignments for the
past week and a half. I found some time to review your proposal this past
weekend and it looks good overall IMO. A few follow up comments/questions:
>> (As the following design comes from one of our commetrial application. We
>>can use it only if someone of you implement it and donate it into Apache
>>IoTDB Repository. And all variants of this algorithm need to claim it is
>>derived from this algorithm.)
Could you give pointers to this application or is it proprietary?
>> (Improvement: considering the memory cost, we can only keep a part of the
>>table in memory as a cache.)
I would suggest adding another config value in iotdb-engine.properties
specifying the max number of entries in the in-memory Map<metric_name,
Map<tag_key, tag_order>> table, what do you think?

> IoTDB is a highly efficient time series database.
> Prometheus is a monitoring and alerting toolkit, which supports collecting
> data from other systems, servers, and IoT devices, saving data into a DB,
> visualizing data and provides some query APIs.
>
> Prometheus allows users to use their database rather than just Prometheus DB
> for storing time series databases.
> This proposal is for integrating IoTDB with Prometheus.
>
> You should know:
> * How to use Prometheus
> * How to use IoTDB
> * Java and Go language
