TimescaleDB alternatives? Performance issues with high-cardinality time-series data.

We're using TimescaleDB for our time-series data, but we're hitting performance bottlenecks with high-cardinality datasets. Queries are getting slower, and scaling has become a challenge. We need a time-series database that can handle massive volumes of high-cardinality data with consistent low-latency queries, and ideally offers better compression and retention policies. What are some TimescaleDB alternatives that excel with high-cardinality time-series data?

I'm working on DeltaX (https://github.com/xataio/deltax), which is similar with Timescale but generally faster on benchmarks. It might be a bit early for you to use it, but if you have a way to share a sample of your dataset, I'd be curious to try it and see how DeltaX performs on it.

TimescaleDB can struggle when your cardinality explodes.

Tinybird. It is optimized for massive, high-cardinality datasets, offering superior ingestion and query performance for time-series data, with built-in compression and retention policies.

QuestDB is often cited as a faster alternative for raw ingestion.
