Some observations:

• Not sure why our charset is latin1 when the default in the wild is utf8. Latin 1 encodes < 256 characters, whereas utf8 is more robust.
• There are indeed indexes in the database! (my bad 😝) KEY == INDEX

TO DO

• Run a CPU profile against an observational API query to find out where the bottleneck is. Could leverage @JustinElms prior work with the plotting scripts?
• EXPLAIN QUERY should help with figuring out what the DB is doing under the hood IF the DB is the bottleneck.

[dwayne-hart]

That must come in from sqlalchemy.
