Moving Concourse Pipelines

Currently concourse does not support moving pipelines between teams via fly CLI. There is an issue for that here

The only way to do this is to make a few changes in the DB.

If you run the statement below you will see that 6 tables have the team_id column.

concourse=> select table_name                                                                                                                                                                                                                                                                                                                                                       from INFORMATION_SCHEMA.COLUMNS

BOSH Links: Why and How

Audience: anyone in the BOSH ecosystem, whether you work on something open-source or proprietary

"BOSH Links" is a feature which simplifies how data is shared between BOSH-deployed jobs that need to collaborate with one another (e.g. a web server and its backing database). Like many BOSH things, the whole "BOSH Links" thing can seem counter-intuitive at first, and it may not be clear why things are the way they are. This note hopes to show some of the powerful benefits of BOSH Links, and provide examples and explanations that make things more intuitive.

1. Why?
2. BASIC: A simple problem statement
3. BASIC: Putting the puzzle pieces together
4. ADVANCED: But what about...

Don't use MongoDB

I've kept quiet for awhile for various political reasons, but I now feel a kind of social responsibility to deter people from banking their business on MongoDB.

Our team did serious load on MongoDB on a large (10s of millions of users, high profile company) userbase, expecting, from early good experiences, that the long-term scalability benefits touted by 10gen
