This document is a work-in-progress and represents a very early state of the

|
|
|
|
Cells design. Significant aspects are not documented, though we expect to add
|
|
|
|
|
them in the future. This is one possible architecture for Cells, and we intend to
|
|
|
|
|
contrast this with alternatives before deciding which approach to implement.
|
|
|
|
|
This documentation will be kept even if we decide not to implement this so that
|
|
|
|

we can document the reasons for not choosing this approach.

# Cells: Router Endpoints Classification
|
|
|
|
|
|
|
|
|
|
Classification of all endpoints is essential to properly route request
|
|
|
|
|
hitting load balancer of a GitLab installation to a Cell that can serve it.
|
|
|
|
|
|
|
|
|
|
Each Cell should be able to decode each request and classify for which Cell
|
|
|
|
|
it belongs to.
|
|
|
|
|
|
|
|
|
|
GitLab currently implements hundreds of endpoints. This document tries
|
|
|
|
|
to describe various techniques that can be implemented to allow the Rails
|
|
|
|
|
to provide this information efficiently.
