Examples

The following sample code shows how to delete a secondary index from a data table by calling the dropIndex method.

client.dropIndex({
  mainTableName: "<TABLE_NAME>", // Specify the name of the data table.
  indexName: "<INDEX_NAME>" // Specify the name of the index table.
}, function (err, data) {
  if (err) {
    console.log('error:', err);
    return;
  }
  console.log('success:', JSON.stringify(data, null, 2));
});
