[h2] Re: Interfaces instead of direct JTS reference
Hi, This is a good idea. Few suggestions: - IEnvelope, IGeometryFactory, IGeometry and GeometryParseException should be in the API package of H2. - User defined function should be able to directly reference the wrapped spatial type. Then maybe add two methods like this interface http://docs.oracle.com/javase/7/docs/api/java/sql/Wrapper.html and manager this case when calling user defined function and table function. - H2 should provide itself a default implementation for ease of use (stackoverflow question http://stackoverflow.com/questions/27943435/what-is-the-syntax-for-running-a-spatial-query-in-h2/27949066#27949066). To change default implementation class you could use sys properties http://www.h2database.com/javadoc/org/h2/engine/SysProperties.html. - Currently all type of geometry are merged together into Geometry type. We should find a way to add a constraint to define for ex. a LINESTRING column that stay LINESTRING column when copying the table.

Re: [h2] 1.4 beta creates much bigger database file
I also had problems with an mvstore db growing out of control (about 3GB
for 1M rows). I updated to 1.4.184, reimported, and it was much smaller
(100MB).
So the recent changes have had a very positive effect.
Unfortunately, I was using 1.4.178 because that was the current jar bundled
with the jdbc-h2 ruby gem. That version doesn't seem like such a good
default.

Some initial results: you can shrink the database by running
shutdown compact or shutdown defrag. Each time this is run, it
shrinks
a few MB (up to some point, of course). This works, but it's relatively

fully to the minimum size, and shrink it incrementally (like now) but
faster. I'm working on that now.
