Hi,
I've made a hack in pmapper few years ago. This one allows you to
specify 2 data sources for each layer:
LAYER
.....
DATA "the_geom FROM your_heavy_view USING UNQIUE gid"
METADATA
PM_RESULT_DATASUBSTITION "the_geom FROM your_geo_table USING
UNQIUE gid"
...
END
...
END
For instance " your_heavy_view" is a view that join a geographical table
("your_geo_table") with many other tables. The attributes "the_geom" and
"gid" have to be the same names and values in both table and view.
The "DATA" value is the habitual one whereas "PM_RESULT_DATASUBSTITION"
is used to draw / select / query graphically / etc... to speed up pmapper.
Be careful : all attributes used for label, classitem, binding, etc..
have to be in the main table.
It has only been tested with postgreSQL/postigs but could works with
other data types.
