Hi community,
I’m working on adding per-workspace WFS 2.0 Stored queries support.
The core concept is that we will allow the creation of stored queries per workspace:
-
when creating a stored query, if a workspace virtual service end-point is used, then the query will belong to that workspace:
- but that query will only be visible \ usable from that workspace virtual end-point
-
if no workspace virtual service is used, then the stored query will be global
In terms of stored queries usage (list stored queries, execute a stored query, etc …): -
when targeting the global GeoServer end-point, only global stored queries will be visible:
- hence two stored queries of different workspaces can have the same id
-
when targeting a workspace virtual service end-point, the workspace stored queries and global stored queries that don’t collide (don’t have the same id) will be considered:
-
considering also global queries will allow the definition of more generic stored queries, hence removing the need of duplication
-
considering global queries will be activated by default, but can be deactivated (flag in the WFS workspace configuration)
-
In terms of backwards compatibility:
-
global stored queries will be stored as they are now, so no data directory migration need
-
for backwards compatibility, a flag deactivating per workspace stored queries will be added:
- if an user was using a virtual service end-point for creating stored-queries (we can do that now but the stored query will be global anyway), it can use that global flag to deactivate the new functionality
I would like to backport this feature, so proposed default behavior is:
- Activated by default on master branch.
- Deactivated by default on backport branches.
Do you have comments, suggestions on this plan?
Current PR for master branch, if anyone wants to check/review:
