DROP GRAPH

In the analytical mode, the fastest way to delete everything in your current database is by issuing the following query:

DROP GRAPH;

The query allows the user to delete all the data, along with all the indices, constraints, triggers, and streams, in a very efficient manner. For this query to succeed, the user must ensure that Memgraph is operating in the IN_MEMORY_ANALYTICAL storage mode. The user must also ensure that DROP GRAPH is the only transaction running at the time of issuing the command. If any other Cypher query is running when DROP GRAPH starts to execute, it will prevent this command from running until all the other queries are finished.
