2014-09-29 Significant performance improvements in the H2 SQL database. New indexing system; existing tables won’t work. You need to delete the existing tables. Next, create a new table and import your data again. On an i3 laptop it takes 2-3 seconds to complete a search in 1.5 million TUs.

Within seconds, your gigantic database is queried and all matches are displayed:

The database used in the demonstration movie contains 2 million TUs from the DGT. Note that 'Verordnung' and 'Kommission' are very frequent in the DGT, so collecting all hits takes more time.

I wonder... Oct 3, 2014

... how this compares to TMLookup (which uses sqlite without any added special sauce).
It does look very fast on the youtube video. Care to do a comparison test?

Michael's at it Oct 3, 2014

Michael Beijer is doing some tests with his huge resources (45 GB). I'm quite sure he will report as soon as he's ready.

Igor is going to add MySQL soon, and I suppose SQLite will be next. That would be a nice test, CT SQLite against TMLookup SQLite.
