Note: The db usage in my case may not be typical.
did not work well for me:
administration tools are not user friendly
could not quite figure out how to load data from a file
Nice adminstration tools
Deployment is very simple and well explained in documentation
Speed: in my case slower than MySQL
* Preferered choice in my case
Very nice db, but deployment is rather heavy
I was considering HSQLDB as my primary choice of in memory database. After reading its history on http://en.wikipedia.org/wiki/HSQLDB :
HSQLDB is a relational database management system written in Java. It is based on Thomas Mueller's discontinued Hypersonic SQL Project.[1] He later developed H2 as a complete rewrite.
I decided to give H2 a try. Bellow is the benchmark from the H2's website, which looks quite nice. Hopefully my application will achieve similar results.
My application. I am currently running my algorithm on the top of Taste recommender engine using MySQL. A complete set of experiments for my algorithm and existing to produce results takes 3 days on a Core2 Duo machine. I need to try more than 20 different settings = 60 days. So I decided to try to speed it up. In addition I don't have permission to install db on the supercomputing cluster at my university so in memory db hopefully will solve both of my problems.
Since memory's I/O is much faster than disk I/O this should translate into significant speed up (assuming your db can fit in memory)
Could be run in embeded mode -- all you need is java and you can run it locally inside of your application (no additional sotware needs to be installed on the server etc.).
Note: I am using this setup for explorative learning algorithm; it is not a typical usage of the recommender system.
Single pass: 138 - 3,819 ms (depending on configuration)

Solution:
INSERT INTO TASTE_PREFERENCES SET USER_ID='22', ITEM_ID='378', PREFERENCE='5.0' ON DUPLICATE KEY UPDATE PREFERENCE='5.0'
Was giving the above exception. Replaced it with:
INSERT INTO TASTE_PREFERENCES (user_id, item_id, preference) VALUES ('22', '378', '5.0') ON DUPLICATE KEY UPDATE PREFERENCE='4.0'
Then ... ON DUPLICATE KEY UPDATE PREFERENCE='4.0' part was not a standard SQL syntax (perhaps specific to MySQL).
A better way would be to use an ANSI/ISO standard command MERGE ( instead of other db specific variants ) e.g.:
MERGE INTO TASTE_PREFERENCES(user_id, item_id, preference) key(user_id,item_id) VALUES ('22', '378', '4.0')
wrote H2JDBCDataModel.java
I finaly got H2 to run (most of the changes where migrating incompatible SQL from MySQL to standard SQL)
The performance of it was rather slow:
INFO: It took ms: 2,119,766
Used memory-only mode http://www.h2database.com/html/features.html#memory_only_databases
INFO: It took ms: 140,568
Thats a 10 fold improvement
Let JVM use more memory; let db use more memory
Did not help
Installed TPTP for eclipse but does not work; could not figure out why
Using NetBeans to do profiling; is throwing some of the old error for some reason.
Fix: The problem with error was that class in jar was not correctly overwritten by NetBeans
For some reason when running from NetBeans userNeighbourhood.size = 0; but when running from command line the same files it is not
Fix: The problem with error was that class in jar was not correctly overwritten by NetBeans
Surprisingly the peformance of MySQL MyISAM and MEMORY engine are almost identical.

Use Text Table ; also see src/org/hsqldb/sample/load_binding_lu.sql
Error: table not found in statement [SET TABLE SOURCE] / Error Code: -22 / State: S0002
Possible Reason: Text Tables cannot be created in memory-only databases (databases that have no script file).
Tried example from src/org/hsqldb/sample/load_binding_lu.sql
CREATE TEXT TABLE binding_tmptxt (
id integer,
name varchar(12)
);
Error: Database is memory only in statement [CREATE TEXT TABLE binding_tmptxt] / Error Code: -63 / State: S1000
Solution: this statement is not allowed for in memory database; start server db instance

Solution: none
Performance of H2 is 10x slower than MySQL. The difference of code between two implementations is that for
H2: MERGE INTO
MySQL: INSERT ... ON DUPLICATE KEY UPDATE
Changed it but did not make a difference.
Disabled/Enabled Connection pooling but did not produce significant affect either.
Since performance still is not good rewrote code for the methods that take too long; and wrote new classes optimized for my task as seen in the next blog posting ....
http://www.h2database.com/html/features.html#trace_options
TRACE_LEVEL_SYSTEM_OUT=3
Do also java code generation; this way can benchmark it against MySQL and see where the problem is.
Turn on logging finest
See performance for my AL method and optimize for it - since it is the slowest one anyway.
If performance still is not good may need to rewrite code for the methods that take too long; or write new classes optimized for my task
For example: may compute user neighborhood only for the specific items; since I need to get estimates for only a few items, etc.
