Bit of safety: backup and restore extension
● Save the configuration to a zip file (not the
data!)
● Restore later, in the same or different
environment
● UI to run backup and restore
● Async operations
● REST Interface
● During backup the configuration is read only
● During restore it’s fully locked
● Support “dry run” to for errors prior to restore

Only want to play with MVT? Ok!
● Extension for publishing vector tiles
● Great solution for modern High

● Client side styling
● Use for GeoServer for “MapBox
without MapBox”
● Also to do “MapBox with OGC fallback”

GeoWebCache
● Tile caching application
● Can cache tiles in
PNG/JPG/KML/MVT/GeoJSON
● Can store tiles in file
system/SQLite/S3/Azure
● Supports WMS-C, TMS, WMTS
Slide 37

Runs integrated in GeoServer
● Configuration integration
○ Configure layer once
○ Setup via GUI
● Security integration
○ Configure security once
○ Limited checks (only layer access, no
attributes, areas and alphanumeric
filters)
● Event integration
○ Change styles, tiles dropped
○ WFS-T transaction, tiles dropped
● Service integration
○ Direct integration
○ Intercept tiled requests from WMS and
uses cache for them

CQL
POP_EST <= 5000000 AND

● E-CQL - extends this basic concept to
do everything Filter can do
