On AI and Data Technology Innovation in the Rail Industry. Interview with Gerhard Kress

“I think the biggest challenge is that in the rail business we have a very large set of old and country specific regulations that date back many decades. These regulations are meant to protect passengers, but some of them are not anymore fitting to the modern capabilities of technology and instead drive cost and slow innovation down dramatically.” –Gerhard Kress

Artificial intelligence acts as an enabler for many innovations in the rail industry.
In this interview, I have spoken with Gerhard Kress, who is heading Data Services globally for the Rail business, and is responsible for the Railigent platform at Siemens. We discussed innovation and the use of AI and Data-driven technologies in the transport sector, and specifically how the Siemens` Railigent platform is implemented.

On RDBMS, NoSQL and NewSQL databases. Interview with John Ryan

“The single most important lesson I’ve learned is to keep it simple. I find designers sometimes deliver over-complex, generic solutions that could (in theory) do anything, but in reality are remarkably difficult to operate, and often misunderstood.”–John Ryan

John Ryan: The single most important lesson I’ve learned is to keep it simple.

How to troubleshoot MySQL replication issues?

In MySQL a big portion of the problems you’re facing is different replication delays so there’s no surprise this is one of the most common interview questions on DBA interviews and I still found people having problems with explaining what they would do in a certain situation. This is why I decided to write a bit about the subject.

1. IO

99% of times the reason is IO. The slave cannot keep up with the amount of writes it gets from the binary logs while in parallel it has to return results of queries as well. In spite of the common belief in MySQL it’s much easier to saturate the disk subsystem (even a raid 10 with 8 SAS disk and cache) than the network.

In this situation all you can do is try to remove some pressure from the slaves.

One way to do this is setting innodb_flush_log_at_trx_commit  to 2 if it used to be 1. Usually this is enough.
