Docs: Add TIDB to Comparison page in CockroachDB Docs

[pirate]

PingCAP's TIDB is not listed on your CockroachDB in Comparison page.

There's definitely some demand (hn, hn, reddit) for a comparison between the two.

They seem to be the only major competitor that's doing exactly what you're trying to do (correct me if I'm wrong here).

If CDB has more features and has TiDB beat, awesome, I'd love to see how far ahead CDB is!

Thanks for the suggestion, @pirate.

Thanks for the suggestion @pirate. To build the comparison matrix, we chose a handful of representative databases from different categories. We’ll keep an eye on TiDB, but for now we’ll leave Spanner as our NewSQL point of comparison. If you’re looking for a more robust comparison of production-ready databases, I recommend looking at dbengine.com.

Cockroach is exactly the same as TiDB, just for Postgres.
This is why people are interested in a comparison.
It is comparing apples with apples.

"exactly the same" except the design is fundamentally different :)
TiDB has a central component that all transactions need to contact, which prevents geographically-distributed clusters. CRDB supports geo-distributed clusters.
Also, TiDB provides snapshot isolation for transactions whereas CRDB transactions are serializable.

Same use case. Drop in replacement for a standard DB. :hugs:
