A short note that the total cost of that SPARC cluster was $30 million. You're not misreading those numbers, but it requires a little context.

We're focusing today on our improvements over CockroachDB 1.1, using a small-ish cluster. We'll be showing some more scalability with larger clusters in the coming weeks. If you've found CockroachDB performance slow in the past, you will be pleasantly surprised with this release!

Sure thing. I was primarily answering the question above - in terms of how the numbers in the TPC-C benchmark fit in. I updated my comment to reflect the cost.

I think what's interesting with TPC-C is that you can sort the results based on performance or price/performance. On the price/performance metric, SPARC looks expensive. Dell has a $20K SQL Anywhere cluster that can do 113K tx/min.

I wonder if anyone tried to run these benchmarks on the cloud and how one would calculate total cost of ownership there now.

How is this meaningful without detailed setup description? http://www.tpc.org/tpcc/results/tpcc_results.asp?print=false... Looking at this list of results one wonders what those results actually mean?

I think you can still drive some insights. I clicked on the TPC-C results you shared and read their executive summaries.

The Oracle on SPARC cluster (at the top, 2010) performs 30.2M qualified tx/min vs the 16K tx/min in this blog post. The Oracle cluster also costs $30M, which is clearly higher than the Cockroach cluster's cost.

That said, the TPC-C benchmark is new to me. Happy to update this comment if I'm misreading the numbers.

These features sound great.

On the Data Migration Tool (DMS), I really wish they would fix important issues related to Postgres. Right now, if you have a JSONB column in your database, DMS truncates the data.

This makes it impractical to use DMS for most Postgres deployments: https://forums.aws.amazon.com/message.jspa?messageID=735961

It doesn't take a year for spouses through USCIS. More like a few months.

(Semi-related) I'm an L-1A spouse. It took my work application 10 months to get processed, when the USCIS' own regulation stated that the it should have been closed in 90 days.

You call them, ask them, plead with them. Nothing. "Your application is in the system and is getting processed."

Nine months into it, it turned out that they lost my digital picture taken at a USCIS facility. How in this day and age one loses digital pictures is beyond me.
