Dmitriy is blogging about speeding up #MySQL by putting its code to huge pages. The library implementing that is on Github, and we believe it is more advanced than alternatives.

@ManjotSingh I can and will try to find time soon. Meanwhile, would https://t.co/MQiadibvBW work for you?

For the last year or so I've started a survey of interesting design ideas about B-tree and related stuff. Never though it would be so deep and interesting. Many whitepapers later I've finally managed to put it together (at least partially).

We propose Pivoted Query Synthesis (PQS), a new approach for finding logic bugs in DBMS (see https://t.co/NboQkq969d). Using PQS, we found ~100 previously unknown (and many critical) bugs in widely-used DBMS (e.g., SQLite3, MySQL, and PostgreSQL). Work with @zhendongsu.

Includes per-CPU caching mode indispensable for highly-threaded servers&extensive huge page support.
Lots of worthy things for low-level hackers.
I contributed to it a bit incl cache capacity balancing

@lefred That bug report was created after investigating an MTR testcase taking unreasonably long for 8.0 debug builds.

INFORMATION_SCHEMA is supposed to be faster in MySQL 8.0, right? Well, sometimes it's hundreds of times slower. https://t.co/Nq2NCg8cDt

This looks pretty cool from Google. Analyzing scheduler task migration on machines with lots of CPUs is a pain without visualisation tools.
