  • Java

  • curl

from astrapy import DataAPIClient

# Get an existing table
client = DataAPIClient("ASTRA_DB_APPLICATION_TOKEN")
database = client.get_database("ASTRA_DB_API_ENDPOINT")
table = database.get_table("TABLE_NAME")

# List index names
result = table.list_index_names()
print(result)
import { DataAPIClient } from '@datastax/astra-db-ts';

// Get an existing table
const client = new DataAPIClient('ASTRA_DB_APPLICATION_TOKEN');
const database = client.db('ASTRA_DB_API_ENDPOINT');
const table = database.table('TABLE_NAME');

// List index names
(async function () {
  const result = await table.listIndexes({ nameOnly: true });

  console.log(result);
})();
package com.example;

import com.datastax.astra.client.DataAPIClient;
import com.datastax.astra.client.tables.Table;

            .getDatabase("ASTRA_DB_API_ENDPOINT")
            .getTable("TABLE_NAME");

        // List index names
        List<String> result = table.listIndexesNames();

        System.out.println(result);
    }
