Batch delete based on condition

[isuhendro]

Is it possible to delete records in batch using NodeJS based on condition?
Below is sample code for batch delete, but preparing taskKey1, taskKey2... etc is not a elegant as putting condition like size > 25

const keys = [taskKey1, taskKey2];

datastore.delete(keys)
  .then(() => {
    // Tasks deleted successfully.
  });

We currently only support delete-by-key. To delete according to a condition, you'd have to run a separate keys-only query() operation, and feed the results into delete() calls.
