Maps/Dynamic tile sources

Dynamic tile sources

Cassandra

To create a new Cassandra data source, post something like this to the /sources as a text body. Default table name is tiles. If table or keyspace is not there, you have to use createIfMissing parameter.

v2a:
  uri: cassandra://
  params:
    keyspace: v2
    table: tiles2a
    cp: [maps-test2001.codfw.wmnet, maps-test2002.codfw.wmnet, maps-test2003.codfw.wmnet, maps-test2004.codfw.wmnet]
    username: {var: cassandra-user}
    password: {var: cassandra-pswd}
#    repfactor: 4
#    durablewrite: 0
#    createIfMissing: true
#    copyInfoFrom: {ref: gen}

Dynamic Layer Generator

To generate just a few layers from database, create a layer filter and a layer mixer:

gentmp:
  uri: bridge://
  xml:
    npm: ["osm-bright-source", "data.xml"]
  xmlSetDataSource:
    if:
      dbname: gis
      host: ""
      type: postgis
    set:
      host: localhost
      user: {var: osmdb-user}
      password: {var: osmdb-pswd}
  xmlLayers: [admin, road]

mixtmp:
  uri: layermixer://
  params:
    sources: [{ref: v2}, {ref: gentmp}]

Once set, POST a job to copy mixtmp into the storage v2 e.g.

src=mixtmp dst=v2 baseZoom=0 fromZoom=5 beforeZoom=6 parts=10
