Hi Umberto,

With respect to the last bit;

I think you only see the amount used if you have Disk Quota turned on.

Re: [Geoserver-users] Vector Tile very slow rendering

[umbertofilippo]

First of all, thanks to everybody for the precious suggestion and time you
took to help me.

So, I have a bit of a doubt now about how to speed up this vecor tile
service after your considerations.

I think the best would be to drastically reduce the number of points at low
zoom levels where they are too dense.
I am talking doing this server-side: should I define a new SLD style with
such zoom-based rule and associate it with my layer then reseeding?
Also, if this is the way to go, how can I reduce the number of points at low
zoom level based on their density (something that another software called
tippecanoe can do as explained  in this blog

 
)?

Also, I saw something about Rendering Transformation and PointStacker, but I
am not sure this is the right way to go, as to my understanding the server
will still need to process data all the time they are requested before
sending them to the client (am I wrong?)

Re: [Geoserver-users] Vector Tile very slow rendering

[Andrea Aime]

Yes, the default style associated to the layer is used to perform filtering
and zoom level dependencies.
It's meant to provide a continuous experience between server side and
client side rendering, if you
use the same style on both ends.
If you just want to do client side rendering, no matter, setup a SLD with
rules that will do the right feature
filtering based on the scale denominator, and use placeholder symbolizers
inside the rules to make
the style formally valid

Cheers
Andrea

Yes, you need to use your SLD connected to the layer in order to filter
out features, using Min- and MaxScaleDenominators or filters.

Styling in SLD obviously does not matter in this case.

You may wish to filter the number of points using rules when you zoomed out
so your vector tiles are not so large.
One of the reasons to do vector tiles is to take control of these kind of
performance considerations.

Well, I cannot really advise something connected with webGL but there might
be some further workaround with GWC.

Re: [Geoserver-users] Vector Tile very slow rendering

[umbertofilippo]

Thanks for the hint!

I enabled it and it now shows 16.55 MB.
I emptied and seeded it again to see if the number was correct and it is
right.

However, the performance of the map is still very poor.

I imagine it has to do with the great number of points to show at low
scales.
Is there a way to control how the tiles are generated (like, selecting an
algorithm to reduce the number of points at low scales or similar?).
The only thing I could found was talking about using tippecanoe software fir
this, but I was wondering if Geoserver has something for it.

You should first enable disk quota. If you see n/a, seeding will do nothing.
When you enable quota, "n/a" will change to 0.0 KB

[Geoserver-users] Vector Tile very slow rendering

[umbertofilippo]

Hello all,

I am using Geoserver 2.16.1 with Vector Tile extension.
I was able to publish a multipoint ShapeFile as a vector tile and see it in
my OpenLayers 6 application.
However, the service is very slow.
I am using the application/vnd.mapbox-vector-tile format as suggested in
https://docs.geoserver.org/stable/en/user/extensions/vectortiles/tutorial.html.
The layer contains millions of points, and as the extent I am viewing is
large the points get very long to display on the map.
Their projection is 900913 and the view of my map is 3857, so I guess this
is fine as there should be no reprojection going on slowing down the
process.
I tried to seed the cache going to speed up everything.
I went into Tile Caching -> Tile Layers ->  and clicking the
"Seed/Truncate" link.
Then, I chose:
 - Type of operation: Seed - generate missing tiles
- grid set: EPSG:900913
- format: application/vnd.mapbox-vector-tile
- scale: 0 to 14.
and pressed submit.
After less than 5 minutes, apparently the process ended successfully, but
under disk usage I still se N/A.
So I guess that no cache has been seeded, right?
What am I doing wrong? Is it not the best choice to use vector tile for my
dataset?

Thanks in advance.

Umberto

Hello all,

I am using Geoserver 2.16.1 with Vector Tile extension.
I was able to publish a multipoint ShapeFile as a vector tile and see it in
my OpenLayers 6 application.
However, the service is very slow.
I am using the application/vnd.mapbox-vector-tile format as suggested in
https://docs.geoserver.org/stable/en/user/extensions/vectortiles/tutorial.html.
The layer contains millions of points, and as the extent I am viewing is
large the points get very long to display on the map.
Their projection is 900913 and the view of my map is 3857, so I guess this
is fine as there should be no reprojection going on slowing down the
process.
I tried to seed the cache going to speed up everything.
I went into Tile Caching -> Tile Layers ->  and clicking the
"Seed/Truncate" link.
Then, I chose:
 - Type of operation: Seed - generate missing tiles
- grid set: EPSG:900913
- format: application/vnd.mapbox-vector-tile
- scale: 0 to 14.
and pressed submit.
After less than 5 minutes, apparently the process ended successfully, but
under disk usage I still se N/A.
So I guess that no cache has been seeded, right?
What am I doing wrong? Is it not the best choice to use vector tile for my
dataset?

Thanks in advance.

Umberto
