Switching from the current split-join enrichment topology to the new unified
enrichment topology can reduce the latency of enrichment messages and avoid overloading the
enrichment cache during times of heavy traffic.
-
Stop the Metron enrichment topology in Ambari.
-
Click Metron Enrichment in the
Summary list.
-
Choose Stop from the menu next to Metron
Enrichment / Metron.
-
In the Enrichment tab, choose Unified
from the Enrichment Topology menu.
Where appropriate, the unified topology reuses the same settings from the
split-join topology.
-
Restart the enrichment topology in Ambari.
