How to batch queries and perform them later in pyneo2 v3?

Question

In py2neo V2, it was possible to do this by using query.append() which add the query to a queue and all the queries can be executed later.

How can I do the same thing in v3? I cannot find an equivalent function in the documentation for this.

Answer 1

The following is in Python 3.6.3 using py2neo version 3.1.2:

from py2neo import Graph g = Graph(host="localhost", user="neo4j", bolt=True) # Modify for your situation transaction = g.begin(autocommit=False) transaction.append("match(n) return count(n);")

This fails and returns the following warning:

/usr/local/bin/ipython3:1: DeprecationWarning: Transaction.append(...) is deprecated, use Transaction.run(...) instead

Hope this helps.
