The behavior of the Windows scheduler changed significantly in Windows 10 2004, in a way that will break a few applications, and there appears to have been no announcement, and the documentation has not been updated. With the Windows 10 2004 (April 2020 release) some of this quietly changed, but in a very confusing way. That’s crazy!

Reference tables can be replicated to all nodes for joins and foreign keys from distributed tables and for maximum read performance. Depending on the configuration, one can tune a hardware RAID for either performance or redundancy. The same can be said for Citus data sharding. The colors indicate duplicated shards of the table.

I became the Sun UK local specialist in performance and hardware, and as Sun transitioned from a desktop workstation company to sell high end multiprocessor servers I was helping customers find and fix scalability problems. Rich became co-author of the second edition of the Sun Performance Tuning book, to describe how it worked.

And asserted conditions only evaluated if they’re enabled, so any side effects won’t happen when they’re not enabled; they might sometimes perform local side effects, such as to do logging or allocate memory, but the program should never rely on them happening or not happening. Assertions are only about finding bugs, not doing program work.

Breaking that assumption allowed Ceph to introduce a new storage backend called BlueStore with much better performance and predictability, and the ability to support the changing storage hardware landscape. The first implementation (c. 2004) was a user-space file system called the Extent and B-Tree based object file system.
