== Description
|
|
|
|
|
|
|
|
|
|
datanommer is a set of three modules:
|
|
|
|
|
|
|
|
|
|
python-datanommer-models::
|
|
|
|
|
Schema definition and API for storing new items and querying existing
|
|
|
|
|
items
|
|
|
|
|
python-datanommer-consumer::
|
2025-02-03 11:11:06 +01:00
|
|
|
A plugin for the fedora messaging that actively listens to the bus and
|
2021-07-26 10:39:47 +02:00
|
|
|
stores events.
|
|
|
|
|
datanommer-commands::
|
|
|
|
|
A set of CLI tools for querying the DB.
|
|
|
|
|
|
|
|
|
|
datanommer will one day serve as a backend for future web services like
|
|
|
|
|
datagrepper and dataviewer.

== Upgrading the DB Schema
|
|
|
|
|
|
|
|
|
|
datanommer uses "python-alembic" to manage its schema. When developers
|
|
|
|
|
want to add new columns or features, these should/must be tracked in
|
|
|
|
|
alembic and shipped with the RPM.
|
|
|
|
|
|
|
|
|
|
In order to run upgrades on our stg/prod dbs:
|
|
|
|
|
|
|
|
|
|
[arabic]
|
|
|
|
|
. ssh to busgateway01\{.stg}
|
|
|
|
|
. `cd /usr/share/datanommer.models/`
|
|
|
|
|
. Run:
|
|
|
|
|
+
|
|
|
|
|
....
|
|
|
|
|
$ alembic upgrade +1
|
|
|
|
|
....
|
|
|
|
|
|
|
|
|
|
____
|
|
|
|
|
Over and over again until the db is fully upgraded.
