Hi Thomas,
Thanks for the suggestion. I tried adding ";retention_time=1000" to
the URL, and this resulted in a small improvement.
pokercopilot.h2.db 302,018,560 bytes
pokercopilot.mv.db 999,120,896 bytes
pokercopilot.mv.db with RETENTION_TIME=1000: 811,728,896 bytes
These numbers all reflect a loading of data in a newly created database
that consisted of roughly 2,400,000 INSERTS and UPDATES with plenty of
SELECTS and almost no DELETES. After the loading was complete, I let the
application keep running with the database open for a few minutes, then
close the application and therefore the database.
Here is the full JDBC url I'm using:
jdbc:h2:/Users/steve/Library/Application Support/com.barbarysoftware.
pokercopilot/database/pokercopilot;DATABASE_EVENT_
LISTENER='com.barbarysoftware.pokercopilot.database.
DatabaseListener';COMPRESS_LOB=DEFLATE;CACHE_SIZE=65536;
RETENTION_TIME=1000
Let me know if there is anything else I can do to help diagnose this.
Regards,
Steve
