When was the last time you tried it? This was the focus of the 0.18 release, which improved the situation quite significantly (see https://rerun.io/blog/column-chunks for details)

wow, this looks very promising! are the cardinality limitations also improved? (ie, if i throw 500 timeseries at it, does the ui handle things gracefully?)

also, how's api stability looking these days? it looks like none of my 0.16 test scripts want to run against 0.18?

The many entities performance is still not where we'd like it to be. We've made multiple improvements over the last releases so worth kicking the tires again but it isn't solved in a fundamental way yet. There is still some low hanging fruit available to speed things up for many common cases of high cardinality by expanding our APIs slightly I believe. Those can come sooner that a bigger architecture update so hopefully that will be enough for your use case

What I love about you guys is that when somebody asks for a feature, you never come back with “sure, maybe we’ll bolt that on”, you come back with “We agree! That’s why we completely rebuilt the thing from scratch to handle that legitimate and central requirement! And still we’re not satisfied!” It’s awesome!
