Deleting specific bin

Like to confirm if there’s any way to delete just a specific bin. As opposed to removing an entire record

Write that bin with type null (not sure of the node semantics for that).

You can do multiple operations per database request - like writing several bins with type null, updating a counter at the same time, in most of the clients.

Yes, set the bin value to null and write the record using .put() like so:

client.put(key, {'BIN_NAME_GOES_HERE': null}, function(err, meta) {
  // check for error etc.
}
