Checking namespace existence

To check if a namespaces exist, execute a Document API query with cURL to find all the namespaces:

cURL command (/v2)
Result

curl -L -X GET 'https://$ASTRA_CLUSTER_ID-$ASTRA_REGION.apps.astra.datastax.com//api/rest/v2/schemas/namespaces' \
-H "X-Cassandra-Token: $ASTRA_DB_APPLICATION_TOKEN" \
-H 'Content-Type: application/json'

{"data":[{"name":"system_distributed"},{"name":"system"},
{"name":"data_endpoint_auth"},{"name":"system_schema"},{"name":"myworld"},
{"name":"stargate_system"},{"name":"system_auth"},{"name":"system_traces"}]}

To get a particular namespace, specify the namespace in the URL:

cURL command (/v2)
Result

curl -X GET 'https://$ASTRA_CLUSTER_ID-$ASTRA_REGION.apps.astra.datastax.com/api/rest/v2/schemas/namespaces/namespaces/myworld' \
--header "X-Cassandra-Token: $ASTRA_DB_APPLICATION_TOKEN" \
--header 'Content-Type: application/json'

{"data":{"name":"myworld"}}
