- We support Lucene-based search, which means it's a lot easier to find the events you're looking for without needing to break into verbose SQL search. (Column/property/full text search are all super easy).
- We're optimized exclusively for Clickhouse, which means we do a number of things to optimize the queries we run and that returns you a nice performance boost (we see a 2x perf boost, but this will vary a ton of data and queries). For example we allow you to do a search on a subset of columns (so the search is performant), and then click in and expand an entire row of interest on-demand (so we only do a SELECT * for a single row). This is also a much nicer DX than needing to specify every column you might need. We have a few other optimizations as well.
- We have (what we think is) a nice chart builder - so you don't need to mess with template variables and macros to build a chart, but still lets you escape hatch out into SQL for the important bits.
- We think our event deltas feature for analyzing traces is pretty neat - afaik this isn't something you get in Grafana. - You can live tail events, I don't think Grafana for Clickhouse has that (I'm a big fan of tail -f)
Overall we focus on trying to bring an easy-to-use high-cardinality observability experience to Clickhouse, whereas Grafana seems to focus more on a highly SQL-dependent dashboard building experience (which has its own advantages of course).
edit: fixed line breaks!
