--------------------------------------------
Summary: KiWiStore ValueFactory performs badly in multi-threaded,
high-load imports
Key: MARMOTTA-166
URL: https://issues.apache.org/jira/browse/MARMOTTA-166
Project: Marmotta
Issue Type: Bug
Components: Triple Store
Reporter: Sebastian Schaffert
Assignee: Sebastian Schaffert
Priority: Minor
Fix For: 3.1-incubating
The KiWiStore currently uses a single dedicated database connection for
implementing the value factory. On highly parallel systems with parallel
imports, this can be the single bottleneck, because the value factory
potentially needs to check the database for every node that is created.
To improve the performance, we could instead use a pool of value factories,
each having their own database connection.
