In Depth Tutorial

[autophagy]

Summary

Now that the Twitter tutorial has been removed from the Admin UI, we should replace it with a tutorial that makes sense for our use case and guides users through a series of CrateDB features.

Detail

Commit 1338d7a removed the old Twitter tutorial, since over time it has become flaky and not fit for purpose. One problem is that the Twitter tutorial was not much a tutorial at all. a convienient way of getting a table with some data to play around with, sure; but as an actual tutorial to teach users about CrateDB it was quite lacking.

My proposal would be to add a multi-stage, interactive tutorial covering basic CrateDB concepts such as:

• Table creation, insertion, deletion, and basic querying.
• Table partitioning.
• Generated columns.
• Using CrateDB functions.

It could also be useful to cover more advanced topics like:

• Sharding
• UDFs
• User/Permission management
• Setting/viewing cluster options
