I'm 40, and I enjoy being 40. I feel that I start to understand why things are the way they are, why other people behave like they do, and why I am how I am. I don't go so far to s…

Correct.

I ran sysbench benchmarks with 30 concurrent connections. The performance gap between InnoDB and upscaledb shrank a bit, but not much. The reason is that most of the performance is…

It's ok! The example storage engine could implement more functionality, just to demonstrate i.e. how rows are serialized/deserialized etc. The test suite was very helpful.

Not necessarily. I ran sysbench with InnoDB and manually switched off transactions, and it was a lot slower. I don't know why - didn't look into it. upscaledb does use transactions…

If that's your definition of atomicity - yes, upscaledb offers atomic operations. If you define atomicity as the "A" in "ACID" then no - BEGIN/COMMIT wrappers are not yet available…

BEGIN/COMMIT is not yet supported. But that's on my TODO list.

Thanks for the insights!

Interesting - thanks for your answers!

Agree for a website. I'm selling software licenses, avoiding personal liability would be interesting (if it was affordable).

"Found a small company (UG) with 500EUR capital to hold rights on the site if you want to further professionalize this project." Can you elaborate a bit? I have the same problem as…

That's interesting - are the 64bit versions available for download?

thanks :) Will try to figure out how to fix this.

I like the VLDB papers, and papers of similar conferences. But most of upscaledb's architecture is auto-didactic. edit: this is a good book: http://db.cs.berkeley.edu/papers/fntdb0…

Engineering team lead. My side project is an embedded key/value database: http://upscaledb.com

Yes, Simdcomp has faster encryption/decryption, but with Delta compression. FOR is a bit simpler and has faster random access.

Absolutely not for me.
