What happened to the project?

I see it is not actively maintained. Did ClickHouse meet any limitations?

In short:

• the latency for queries like "show me the PMM home dashboard" was too high;
• we looked into adding our own caching layer or using something like Trickster;
• in the process, we discovered VictoriaMetrics and liked it;
• and PMM migrated to use it.

VM does not support downsampling yet, but that's planned.

That repository probably should be archived. /cc @atymchuk @shoffman-percona
