As usual, let me start with InnoDB. The following bugs were fixed there:

  • Bug #80296 - "FTS query exceeds result cache limit". It was reported (for 5.6, but I do not see new 5.6 release notes yet) by Monty Solomon and verified by …

WarpSQL now has SQL shim plugins
+1 Vote Up -0Vote Down

I made some improvements to the 'proxy' inside of MySQL 5.7 that I've created for WarpSQL (Shard-Query 3).  I've made the MySQL proxy/shim pluggable and I moved the SQLClient to sql/sql_client.cc.  I've merged these changes into 'master' in my fork.

Now you can create "SQL shim" plugins (SHOW PASSWORD is implemented in plugin/sql_shim) and install them in the server like regular plugins:

-- command doesn't work
mysql> show password;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'password' at line 1

-- install the example sql_shim plugin: …

Faceted search, why the DevAPI could matter one day
Employee +0 Vote Up -0Vote Down

Faceted search or faceted navigation is a highly praised and widely use search pattern. And, it is a great reply to an off the records sales engineering question. MySQL finally has some document store features built-in. A bit of a yawn in 2016. There is a new X DevAPI available with some Connectors. …

On Uber’s Choice of Databases
+0 Vote Up -0Vote Down

A few days ago Uber published the article “Why Uber Engineering Switched from Postgres to MySQL”. I didn’t read the article right away because my inner nerd told me to do some home improvements instead. While doing so my mailbox was filling up with questions like “Is PostgreSQL really that lousy?”. Knowing that PostgreSQL is not generally lousy, these messages made me wonder what the heck is written in this article. This post is an attempt to make sense out of Uber’s article.

In my opinion Uber’s article basically says that they found MySQL to be a better fit for …

Is the new MySQL Document Store and JSON data type cheating?
Employee +1 Vote Up -0Vote Down

Is it cheating? Is using MySQL without Structured Query Language (SQL) or putting all your data into one column proper? Impossible a year ago and probably thought as a poor/crazy practice until recently, this is a new type of MySQL usage. NoSQL has had a big impact in the SQL world with several relational products from vendors like MySQL, Microsoft, Postgresql and others offering NoSQL interfaces and JSON data types to their databases.

Several old timers have come to me asking if putting lots of data in a JSON column is cheating? After all data normalization is part of relational databases and the way to efficiency and speed is well …

SQL Injection Detection and Alerting are Vital For Secure Data
+0 Vote Up -0Vote Down

The recent Mossack Fonesca “Panama Papers” hack is the latest security breach to drive home how much an impact an SQL injection can have on modern-day organizations. Though that hack ultimately revealed massive professional fraud by companies and governments around the world, it involved the exposure of 11.5 million confidential documents. The 2.6 terabytes of data stolen were a powerful reminder that the history of web-based business has been riddled with instances of SQL injections. They remain common and potentially …
