VC backed database company with a CLA on their &quot;open source&quot; project. Red flag. Is there a community fork yet?

I love these new distributed DBs. CockroachDB is one of them. Still I think a managed Postgres&#x2F;MySQL is a better choice. My primary concern is how challenging will it be if you have to eventually move your data out to a RDBMS for cost or other reasons. Does anyone have any experience ? I am not talking enterprise scale but data about size of 50 - 100GB scale.

Hardly hear about TiDB. How is it faring and how does it stack up to more well know competition?

I was able to get a small TiDB cluster running in my homelab last night! Looking forward to using it :)<p>Reference: <a href="https:&#x2F;&#x2F;docs.pingcap.com&#x2F;tidb-in-kubernetes&#x2F;stable&#x2F;get-started" rel="nofollow">https:&#x2F;&#x2F;docs.pingcap.com&#x2F;tidb-in-kubernetes&#x2F;stable&#x2F;get-start...</a>

What is that first paragraph? &quot;This implementation proves the CAP theorem as wrong&quot;? Doesn&#x27;t tell me what your drawbacks are. This is mongodb all over again. Will only ever consider if the customer really wants it. (My guess performance)<p>(Also, bold move to write a db without fully being able to manage memory).

Not having a single binary distribution like CockroachDB is hurting adoption of TiDB.

Does &quot;cloud native&quot; mean &quot;has kubernetes config&quot; or is there something else to it?
