Hi all,
I'm sorry if this question is not relevant here.
I'm learning ArangoDB at the moment. However I got confused by the document
when deleting the graph.
Here is the
link:
https://docs.arangodb.com/3.0/Manual/Graphs/GeneralGraphs/Management.html#remove-a-graph
It says that
"A graph can be dropped by its name. This will automatically drop all
collections contained in the graph as long as they are not used within
other graphs. To drop the collections, the optional parameter
*drop-collections* can be set to *true*."
However, the example shows the difference.
Drop a graph and keep collections:
arangosh> var graph_module = require("@arangodb/general-graph");
arangosh> graph_module._drop("social");true
arangosh> db._collection("female");
[ArangoCollection 16361, "female" (type document, status loaded)]
arangosh> db._collection("male");
[ArangoCollection 16363, "male" (type document, status loaded)]
arangosh> db._collection("relation");
[ArangoCollection 16365, "relation" (type edge, status loaded)]
arangosh> var graph_module = require("@arangodb/general-graph");
arangosh> graph_module._drop("social", true);true
arangosh> db._collection("female");null
arangosh> db._collection("male");null
arangosh> db._collection("relation");null
As the document said, I expect in first example the collections will get
deleted, however it is not.
Could someone please explain it?
Thank you in advance,
Bang
