I was chatting with Andrea Aime when he pointed out (thanks!) that there is no
way to know what is the
current time in a CQL filter ... which means that there is no way to filter polygons that have been
inserted
only in the last five minutes.
So I see two options here:
1. you need a collection that will only have the relevant polygons, e.g.
some collection that
will be updated
by an external service adding recent (last 5 minutes) polygons and
removing deprecated ones
2. extend GeoServer CQL filtering support to be able to filter based on the
current time
Hope it helps.

Hi,
You only App-Schema if you are dealing with complex features or if you need to comply with a
specific XML schema,
otherwise you only need the mongodb data store, i.e. you only need simple
features support.
When publishing a MongoDB collection in GeoServer as a layer, by default GeoServer will consider
all the data available
in the collection. In you case you may want to use a CQL filter [1] to restrict GeoServer to only
take into account
the polygons that have been inserted in the last 5 minutes.
Kind regards,
Nuno Oliveira

Hi all,
I have a database in mongodb with polygons, each polygon has a date and new polygons are inserted
every five minutes.
Now, I'd like to create a layer with the polygons inserted on last five minutes, how can I do
this? Should I use app-schema or gt-mongodb plugin?
