I'm running the current docker image in Windows. I discovered this problem when my program encountered a large book and tried to ingest sentences from it. I was able to reproduce the problem with a more simple example in a jupyter notebook.

from string import ascii_letters r = redis.Redis(host='localhost', port=6379) def get_mutated_string(s): #This is just so we have some way of generating lots of strings different from the last. inds = [i for i,_ in enumerate(s) if not s.isspace()] sam = random.sample(inds, 3) letts = iter(random.sample(ascii_letters, 3)) lst = list(s) for ind in sam: lst[ind] = next(letts) return "".join(lst) #this is just to reset the graph when trying different amounts of nodes. try: rg2.delete() except: pass rg2 = Graph('bulk_test', r) nodes=[] edges=[] last = None s = "Jean Piaget" for i in range(9041): new = Node(label='name', properties={'w': s}) nodes.append(new) if last is not None: edges.append(Edge(last, 'mutate', new)) s= get_mutated_string(s) last = new for n in nodes: rg2.add_node(n) for e in edges: rg2.add_edge(e) #Like commit, but sets nodes and edges to empty. Multiple flushes don't cause duplicates. rg2.flush() 

If the range is only 9040, no errors. If I increase it to 9041 or higher, I get this error:

Error

Depending on your machine or the size of the nodes, the number could differ (like 10000 or 20000).
I was also able to cause this problem with only one node that had a large property.

Expected behavior:
Tell me if the content of the commit is too large
Or
Handle it gracefully.
