[Geoserver-devel] RE: Geoserver doing entire table scans?

Gregory_S_Williamson · January 7, 2005, 3:50pm

What does "Property namespaces returned a null value" mean to anyone ?

Certainly "SELECT gid FROM parcels" will do a full table scan; no other way to do such a thing ... the question would be why the geoserver is wanting to do this ... if it is just once as it sets something upmaybe survivable but obviously this won't be allowable in runtime.

Subject: Geoserver doing entire table scans?
Hi,

We're running geoserver using postgis as the backend. When I try to
add a huge table as a WFS feature via the web interface, I get a http
500 out of memory error.

I've set geoserver from SPEED to FILE. I've also noticed that Geoserver
appears to do an entire table scan whenever I try to add a new feature
because we see "SELECT GID from xxx" on the postgres log. Here's an
example:

2005-01-07 15:13:56 LOG: duration: 620088.450 ms statement: Select gid
from parcels

Here's the stack trace:

So it looks like my hacked solution to a fairly obscure WFS spec problem
is finally exposed - sorry about the hack.

So the reason is does this is the requirement of the spec to return the
new featureid of the inserted Feature. We knew that our solution would
eventually hit the scalable ceiling, so it looks like it's time to fix it.
The problem is that there's no default way that we get the featureid (fid)
- if there's a primary key we use that, if there's not we use the oid,
ect. So the easiest thing to do was to take a diff before and after the
insert. And thus a table scan, to just get the fids, since after the
insert there would definitely be a new one, and that would the proper fid.

The easy solution to this problem is if you don't care about getting the
featureid back from the insert statement. You can just comment out the
addFeatures method of PostgisFeatureStore and it will then inherit from
JDBCFeatureStore and use its addFeature method, which does not try to get
the proper FID. And actually looking at the code someone already
commented it out on 2.0.x of GeoTools, and it looks like GeoServer 1.2.3
and 1.2.4 picked up the change (I just tested and it didn't do a table
scan and it returned a bogus fid). So if you upgrade to 1.2.3 it should
fix your problem, as long as you don't actually need the featureid
returned.

But we really should not have put out a release that doesn't follow the
spec correctly. Anyone know a good way to figure out what what the fid of
an inserted statement is? The execute stuff in the JDBC Statement says it
returns the 'row count', which I suppose is just how many rows were
affected, not the number of the row affected. I suppose we might be able
to make a constraint like the proper fid for an insert statement only
works on an autoincrement table, and then hopefully there's a way to dig
out what the next value would be from JDBC.

I'm on vacation at the moment, so I can't dig into the latter, but it
really should be fixed. If you do need the featureids for your inserts
then you can start digging into it, and I should be able to help out in a
couple weeks. If not just try using a version later than 1.2.3 (you
probably can just grab the geotools.jar from it), or compile your geotools
jar with the addFeatures method of PostgisFeatureStore commented out.

best regards,

Chris
