Defect HC-13229
Parallel NRTs crashing Nifi
Software
Customer case | Applies to | Corrected in |
---|---|---|
CS0268148 | V9.1.6.0 | 9.1.9.0 |
Observed behavior
When multiple NRT indexing operations are run at the same time, NiFi processing can end abruptly. This has been known to happen during Rule Based Sales Category processing when there are several of these categories in use.
Expected behavior
Concurrent (parallel) NRT indexing operations should not have a negative impact on system stability.
Resolution
Improper handling of database connection pooling caused multiple concurrent operations to compete for resources, leading to NiFi processing to end. The database connection pooling was fixed to avoid this situation.
