Description

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.
