GeoMesa Java API

If the current classpath contains the GeoMesa code, you can obtain the HBase datastore instance using a GeoTools API. To obtain the HBase datastore, classpath must contain hbase-site.xml, including HBase datastore connection parameters hbase.zookeeper.quorum and hbase.zookeeper.property.clientPort.

Map<String, Serializable> parameters = new HashMap<>();
parameters.put("bigtable.table.name", "geomesa");
org.geotools.data.DataStore dataStore =
    org.geotools.data.DataStoreFinder.getDataStore(parameters);

DataStore contains only one parameter.

  • bigtable.table.name: Name of an HBase table for storing feature data.

For more information about Java APIs, see the GeoTools API and visit http://docs.geotools.org/stable/userguide/.

  • LockingManager and Listener related APIs are not implemented due to GeoMesa lock management mechanism and other causes.
  • In the current version, you are not advised to use the following APIs to modify the feature attribute. 
    FeatureStore.modifyFeatures(Name[], Object[], Filter)
FeatureStore.modifyFeatures(AttributeDescriptor[], Object[], Filter)
FeatureStore.modifyFeatures(Name, Object, Filter)
FeatureStore.modifyFeatures(AttributeDescriptor, Object, Filter)
SimpleFeatureStore.modifyFeatures(String, Object, Filter)
SimpleFeatureStore.modifyFeatures(String[], Object[], Filter)

    You can modify the feature attributes by searching for and insert a feature to overwrite the old one.

    FeatureSource.getFeatures(Filter)
FeatureStore.addFeatures(FeatureCollection<T, F>)
