issues

Columns duration, totalDistance and totalEnergyBurned should be converted to float.

Sorting that by date makes sense for seeing most recent points, and my DB has 2.5m points in so it's an expensive sort!

Got this error today against a fresh export:

table activity_summary has no column named appleMoveTime

I just ran the script and it failed to import any workout_points, though it did import workouts.

I'm using an XML pull parser which should avoid the need to slurp the whole XML file into memory, but it's not working - the script still uses over 1GB of RAM when it runs according to Activity Monitor.

I think this is because I'm still causing the full root element to be incrementally loaded into memory just in case I try and access it later.

http://effbot.org/elementtree/iterparse.htm says I should use elem.clear() as I go. It also says:

The above pattern has one drawback; it does not clear the root element, so you will end up with a single element with lots of empty child elements. If your files are huge, rather than just large, this might be a problem. To work around this, you need to get your hands on the root element.

So I will try that recipe and see if it helps.

Closes #7

Showing a progress bar would be nice, using Click.

The easiest way to do this would probably be be to hook it up to the length of the compressed content, and update it as this code pushes more XML bytes through the parser:

I don't think there's much benefit to having all of the different record types stored in the same enormous table. Here's what I get when I use _facet=type:

I'm going to try splitting these up into separate tables - so HKQuantityTypeIdentifierBodyMassIndex becomes a table called rBodyMassIndex - and see if that's nicer to work with.
