Open source, resilient, scalable, geo-distributed & runs anywhere, YugabyteDB is the ideal modern #distributedSQL DB for transactional #cloudnative apps!

Share the love & nominate #YugabyteDB for BEST #CLOUD DATABASE in the DBTA Reader's Choice awards!🚀

They probably have a good scalable database behind that 😁

Excellent thread by Franck debunking false claims by @CockroachDB. Essentially, their only defense against @Yugabyte seems to be "started with Postgres, so cant be cloud native" without waiting to think that they are being asked by users to build UDFs, a core Postgres feature 😉

[Franck Pachot @FranckPachot]

🪳A recent announce from CRDB was plain wrong about how @Yugabyte re-uses @PostgreSQL and here are the facts: https://t.co/GmuzTgXWGD
🧵that's the occasion to look back at their "CockroachDB in Comparison" full of 🤡 claims on all DB compared. I'll detail the ones about YB 👇🏻

PostgreSQL is in the news this week.

1. Google continues enhancing Postgres compatibility for Spanner (+ AlloyDB changes): https://t.co/m1DaN1aIlE

2. Microsoft introduced a Postgres interface for CosmosDB:

YugabyteDB was and is on the right track!

The fossil fuel industry WANTS you to lose hope.

They spend billions of dollars spreading doomism, denialism, delay, deflection, and disempowerment.

@vlad_mihalcea @rponte @FranckPachot @Yugabyte +1 that the words "optimistic" and "pessimistic" just add to confusion. However, note that in YB's optimistic locking doesn't detect conflicts at commit time, they are detected immediately. So it is not optimistic like "optimistic concurrency control"

[Piyush Jain @pjain415]

@rponte @vlad_mihalcea @FranckPachot @Yugabyte A correction to the blog post @vlad_mihalcea - both pessimistic and optimistic locking schemes implicitly take locks in YugabyteDB to avoid the dirty write issue. However, they differ in whether to "wait" or "abort" txns when a conflicting lock mode acquisition is attempted.

[Piyush Jain @pjain415]

@denismagda @rponte @vlad_mihalcea @FranckPachot @Yugabyte Correction here -- YDB locks at the finer col level even without pessimistic locking and locks are used at isolation levels. I think what you mean to say is a txn "waits" on locks only when YDB is run in pessimistic locking mode (which is at the moment only for read committed)

[Piyush Jain @pjain415]

And here are the docs for YB's read committed isolation https://t.co/AAllP8GF4Y

[Karthik Ranganathan @karthikr]

This is actually very much inline with what the Yugabyte community says too. We actually had to add read committed because that is the most often used isolation level.

Join us today at DSS 2022 to hear me and Rob Sami talk about two recent additions to YugabyteDB's distributed transactional layer that increase parity even further with PostgreSQL: read committed isolation and pessimistic locking

"It's easier than retraining #PostgreSQL devs, says distributed relational database startup."

I have come across way too many people to count who are gainfully employed, committed to making next decade about climate, & unable to do a public search.

Surfacing these people and connecting them quietly to specific companies is a huge opportunity, and can make a huge impact.
