Hi,
I write to know if you develop a temporary layer, deleting after a fixed
period.
My idea is to create a layer and set the time to live for it, after this
period I delete from Geoserver the layer and optionally the data from
filesystem or database.
If the user want to maintain the layer, he can set the layer time at -1.
I need this functionality because I created a wps that calculate temporary
layers and upload this on Geoserver for viewing, but the result layer could
be interesting or not, if the client show interest, he can save him with
time to live at -1.
Any suggestion?
Seems like a job for an extension, you could put the time to live flag
in the layer metadata map, listen to catalog events to catch the layers
that have the flag (and keep their ids in a list or some storage for fast
lookup), then have a timer that polls from this list and checks which
layers need to be expired.
To remove the data you can use DataStore.removeSchema, mind it
has been recently added, so not all stores support it (JDBC ones
do for example) and generally speaking the code doing that is
kind of new.
Cheers
Andrea
