Write data

First, let’s add some data to the users table that you created. Send a POST request to /v2/keyspaces/{keyspace_name}/{table_name} to add data to the table. The column name/value pairs are passed in the JSON body.

cURL command (/v2)
Result

curl -s --location --request POST 'https://$ASTRA_CLUSTER_ID-$ASTRA_REGION.apps.astra.datastax.com/api/rest/v2/keyspaces/users_keyspace/users' \
--header "X-Cassandra-Token: $AUTH_TOKEN" \
--header 'Content-Type: application/json' \
--data '{
    "firstname": "Mookie",
    "lastname": "Betts",
    "email": "mookie.betts@gmail.com",
    "favorite color": "blue"
}'
curl -s --location --request POST 'https://$ASTRA_CLUSTER_ID-$ASTRA_REGION.apps.astra.datastax.com/api/rest/v2/keyspaces/users_keyspace/users' \
--header "X-Cassandra-Token: $AUTH_TOKEN" \
--header 'Content-Type: application/json' \
--data '{
    "firstname": "Janesha",
    "lastname": "Doesha",
    "email": "janesha.doesha@gmail.com",
    "favorite color": "grey"
}'

{"firstname":"Mookie","lastname":"Betts"}
{"firstname":"Janesha","lastname":"Doesha"}

Notice that, unlike schema creation, data queries do not require tables in the URI, only the {tableName}.

Collections, tuples, and UDTs

Some data types require special handling to write the data. Examples of set, list, map, tuple, and udt are shown, using the column schema created earlier.
