PyOrient Client -
This method allows you to get the number of records in an opened OrientDB database.
There are two methods available in determining the size of the opened database.
db_size() returns the size of the database, while
db_count_records(), which returns the number of records in the database. It takes no arguments and returns a long value.
You might use this method as a basic sanity check in your application. For instance, you might use
db_exists() to determine whether the database was created, then you can use the
db_count_records() to determine whether or not the database is empty.
# Check that Database exists and contains Data if client.db_exists("tinkerhome"): assert client.db_count_records() != 0
