@maxhawkins a limitation of the python mbox module is it loads the entire mbox into memory.  I did find another approach to this problem that didn't use the builtin python mbox module and created a generator so that it didn't have to load the whole mbox into memory.  I was hoping to use standard library modules, but this might be a good reason to investigate that approach a bit more. My worry is making sure a custom processor handles all the ins and outs of the mbox format correctly.

Hm. As I'm writing this, I thought of something.  I think I can parse each message one at a time, and then use an mbox function to load each message using the python mbox module. That way the mbox module can still deal with the specifics of the mbox format, but I can use a generator.

I'll give that a try.  Thanks for the feedback @maxhawkins and @simonw. I'll give that a try.

@simonw can we hold off on merging this until I can test this new approach?","{""total_count"": 3, ""+1"": 3, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",813880401,WIP: Add Gmail takeout mbox import,

> I imagine the reason the column is a `BLOB` for me is that `sqlite-utils` determines the column type based on the first batch of items - https://github.com/simonw/sqlite-utils/blob/09c3386f55f766b135b6a1c00295646c4ae29bec/sqlite_utils/db.py#L1927-L1928 - and I got unlucky and had something in my first batch that wasn't a unicode string.

Ah, that's good to know. I think explicitly creating the tables will be a great improvement. I'll add that.

Also, I noticed after I opened this PR that the `message.get_payload()` is being deprecated in favor of `message.get_content()` or something like that.  I'll see if that handles the decoding better, too.

Thanks for the feedback. I should have time tomorrow to put together some improvements.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",813880401,WIP: Add Gmail takeout mbox import,

The wait is from python loading the mbox file. This happens regardless if you're getting the length of the mbox.  The mbox module is on the slow side. It is possible to do one's own parsing of the mbox, but I kind of wanted to avoid doing that.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",813880401,WIP: Add Gmail takeout mbox import,
