Welcome to Profiling InfiniDB Multi-Join, part of a series designed to highlight different aspects of the InfiniDB join capabilities. InfiniDB is engineered and optimized to execute join operations for millions or billions of rows using a number of key features:

Hash Joins.
Parallel processing (multi-threaded and optionally distributed).
Join sequencing to minimize data shipping costs. (Right-deep join tree instead of left-deep).

Releasing and announcing software is win! I’ve had this bumming around for a bit, and for me (and I think others hacking on MySQL) it’s been rather useful. Simple plugin that takes each email in an mbox, applies the patch and commits it with the correct author to a bzr repo. Very useful if you use quilt and bzr together (“quilt mail –mbox” and then “bzr importmbox”).

I finally published it up at:

enjoy.

When I did NDB Cluster engagements, it happened a few time that I had to cover the NDB API. Once, a customer asked an example on how to perform a simple scan. Remembering that some examples are within the NDB source tree, under ./storage/ndb/ndbapi-examples/ and I decided to take a look, why writing something when a good example already exists... I was not expecting what I found!

1. Missing headers

This is far from deeply technical but little things that should be simple but aren’t annoy me. I found that MySQL Sandbox --prompt_prefix and --prompt_body don’t “just work.” I wanted the prompt to be mysql \v> . So I tried:

make_sandbox_from_source /mysql/src/mysql-4.0.30 single --prompt_body=' \v> '
sh: -c: line 0: syntax error near unexpected token `newline'
sh: -c: line 0: `make_sandbox /mysql/src/mysql-4.0.30/4.0.30 --prompt_body= \v> '

Maybe my shell knowledge is more terrible than I realize so I verified that ‘ \v> ‘ does not need special escaping:

echo ' \v> '
\v>

Ok, so clearly it’s the fault of make_sandbox_from_source. I tried and tried to do this on the command line but …

I'm pleased to announce the release of Memcached Functions for MySQL version 1.1. I realized in the past few weeks, while writing my latest book "Expert PHP and MySQL", that there was no way to obtain the CAS value of a cached item in order to successfully use the function memc_cas(). So, I decided to create a new function, memc_get_cas(), which obtains the CAS value for an item so you can subsequently use this value in a memc_cas() call, which is shown in the example below:

mysql> select memc_get_cas('t1');
+--------------------+
| memc_get_cas('t1') |
+--------------------+
|                  3 | 
+--------------------+
1 row in set (0.00 sec)

mysql> select memc_get('t1');
+----------------+
| memc_get('t1') |
+----------------+
| new value      | 
+----------------+
1 row in set (0.00 sec) …
