Firestore Errors

Most of my apps are using Google’s Datastore, but I decided to try out the new Firestore on a test application. I’m receiving quite a few of the below errors:

io.grpc.internal.ManagedChannelOrphanWrapper$ManagedChannelReference cleanQueue: *~*~*~ Channel ManagedChannelImpl{logId=346, target=firestore.googleapis.com:443} was not shutdown properly!!! ~*~*~* (ManagedChannelOrphanWrapper.java:151)
    Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

These errors stopped when I called close() on the com.google.cloud.firestore.Firestore object after I was done with storage operations:

Javadoc for close() on com.google.cloud.firestore.Firestore.

I can’t help but feel a little disappointed at this new requirement to close the Firestore connection. It feels like a regression from the Datastore – there was no need to close the datastore object after usage.

Firestore Add Document – Python

A simple example of adding a document to the Firestore:

    from google.cloud import firestore
    
    #Make a note in the firestore
    firestore_client = firestore.Client()
    doc_ref = firestore_client.collection(u'CollectionsNameHere').add({
        u'propertyone': u'thisisavalue',
        u'propertytwo': 2,
    })
    logging.warning(doc_ref[1].id)

.add returns a tuple of the date that the document was written into the firestore, and a document reference to the written document. .add lets Firestore create a document ID to the written document: to figure out what the ID is, the last line accesses the tuple and pulls out the document ID.

An item that bit me: the official documentation for Firestore states that .add and .doc().set() are equivalent. That’s true, but the returns from both of those functions are different.

Documentation from Google showing .add and .doc.set are the same operation.

.add returns a tuple of the document creation time and then a reference to the added document. However, .set returns a WriteResult, not a tuple. The WriteResult contains the time the document was updated/set in the property update_time. Make sure to use the correct function as necessary.
