After DS is registered, you can create index tables. Index tables correspond to HBase tables. HBase Ganos automatically creates different index tables based on data types in the GeoJson format. These index tables include property index tables and spatio-temporal index tables. The following table lists the syntax to create indexes:

URL /index/:alias/:index
Method POST
URL parameters alias=[alphanumeric] specifies the name of DS. index=[alphanumeric] specifies the name of the index table, which is used as the unique identifier of the index.
Data parameters points=[Boolean] specifies whether it is a point layer. HBase Ganos optimizes point data storage. date=[alpha numeric] specifies the JSONPath of the time attribute and can be null (no time index is created); id=[alpha numeric] to specify the JSONPath of the feature id; attr=[alpha numeric] to specify the JSONPath of the secondary index attribute, which can be null (no attribute indexes are created); compression=[alpha numeric] specifies the compression option. Valid values: gz, lzo, snappy. Empty (data is not compressed)
Success response Code: 201. Content: empty.
Error response Code: 400, which indicates that some required parameters are not specified. Content: empty.

Example 1: Create an index named my_index in the DS named my_ds and specify the column as the id index.

 curl \ 'localhost:8080/geoserver/geomesa/geojson/index/my_ds/my_index'\

Note that this statement does not create indexes for date, attr. When there are the time or other properties in the query statement, the query will trigger a full table scan.

Example 2: Create an index named my_index in my_ds, set the storage type to Point, set the JSONPath of ID to, set the date to properties.dtg, create a secondary index on the name column, and compress the data.

Curl \
    -d points=true
    -d date=properties.dtg
    -d compression=gz
