There are two types of non-blocking thread synchronization algorithms – lock-free, and wait-free. Their meaning is often confused. In lock-free systems, while any particular computation may be blocked for some period of time, all CPUs are able to continue performing other computations. To put it differently, while a given thread might be blocked by other threads in a lock-free system, all CPUs can continue doing other useful work without stalls. Lock-free algorithms increase the overall throughput of a system by occassionally increasing the latency of a particular transaction. Most high-end database systems are based on lock-free algorithms, to varying degrees.

By contrast, wait-free algorithms ensure that in addition to all CPUs continuing to do useful work, no computation can ever be blocked by another computation. Wait-free algorithms have …

We’re happy to announce the second Release Candidate (RC) of MySQL Workbench.
Version 5.2.22 includes fixes for 76 bugs.

Announcing a new beta 10 release of MySQL Workbench. Version 5.2.20 includes new fixes for 49 bugs (P1 – 1, P2 – 7 , P3 – 39, P4 – 2)

A few new tips you might try. Some have been in the last 2 betas – but in case you haven’t noticed:

1. Once connected in SQL Editor – type control-T or command-T to add a new editor Tab
2. In the SQL Editor run a select. Highlight a cell (one with an image blob preferably) and right click (or command click) and select “Open Value in Viewer” or another option.
3. In a results set — select multiple rows — right click and “copy row content”
4. Click on snippets. Click on the selector and look at DDL and DML lists.
5. Add your own snippets selection drop down option by creating an empty file in the snippets folder and re-opening Workbench.

For example on Windows …

We were honored to give a closing keynote talk at MySQL Conference & Expo 2010, and wanted to share the video with you. Why start a new database company? What is RethinkDB all about? What will database technology look like twenty years from now? In this talk we explore these questions, present some of the exciting technology we’ve been developing at RethinkDB, and show how it fits into our larger vision of what database systems may look like in the future.

Just one week after the latest Beta we are now releasing the next followup build WB 5.2.19 that again fixes a number of issues found in the last Betas. Since beta 8 we were able to close another 32 bugs (P1 – 2, P2 – 4 , P3 – 26).
