-----------------------------------
Summary: TDB2 Graph.size() is much slower than TDB1.
Key: JENA-1562
URL: https://issues.apache.org/jira/browse/JENA-1562
Project: Apache Jena
Issue Type: Bug
Affects Versions: Jena 3.7.0
Reporter: Andy Seaborne
Assignee: Andy Seaborne
Fix For: Jena 3.8.0
TDB2 {{Graph.size()}} is much slower than TDB1.
TDB2 {{Graph.size()}} relies on {{GraphBase.size}}, which uses
{{graph.find(ANY,ANY,ANY)}} which creates nodes and triples unnecessarily for
the count.
TDB1 has code to use the primary tupleindex size() operation and it 50x faster
on 5m triples in the default graph.
