Re: MySQL 5.1 vs. MySQL 5.5: Floats, Doubles, and Scientific Notation

Reading Sheeri's MySQL 5.1 vs. MySQL 5.5: Floats, Doubles, and Scientific Notation, I was baffled at this change of floating point number notation.

However, I was also concerned about the final action taken: using "--ignore-columns" to avoid comparing the FLOAT/DOUBLE types.

The --float-precision option for pt-table-checksum currently only uses ROUND() so as to disregard minor rounding issues. But it can very easily extend to handle the difference in floating point notation. Consider again the problem:

mysql> create table tf(f float);
Query OK, 0 rows affected (0.11 sec) …

The state of MySQL client libraries

Those who’ve been around the MySQL world are probably aware of the much-discussed topics of GPL licensing, dual licensing, and in particular, licensing of the client libraries (also called connectors or drivers) and the FOSS exception to that licensing. This is newly relevant with the announcement of a permissively-licensed MySQL-compatible client library for MariaDB.

The difference is that this time there’s been some question about the provenance and history of the source code. Some people asked me about this. Some of them were aware of a relatively obscure detail: there’ve been permissively licensed MySQL client libraries for years, in the form of libdrizzle, a BSD-licensed library for the Drizzle fork of MySQL.

Here are some of the thoughts that seemed to be going through peoples’ minds:

  • This changes everything, …

The Queen of Evil is back … and she wants your MySQL database skills!

She hired the 400+ original MySQLers … and sets out to hire the SkySQLers of tomorrow! Boel Larsen blogs about open positions & life at SkySQL - and wants you to join the fun!

Those of you who know me also know that I spent over six years working for MySQL HR (for another couple of years I stayed on with Sun).  I joined as employee thirty-something, so running HR meant that I was more or less involved with hiring all of the 400 or so employees who joined after me. I knew pretty much everyone by name.
