Description
When collecting metrics about the number of deltas under specific partitions/tables, information about which partitions/tables are being read is stored in the Configuration object under key delta.files.metrics.metadata. This information is retrieved in DeltaFilesMetricsReporter#mergeDeltaFilesStats when collecting the actual information about the number of deltas. But if the information was never stored for some reason, an NPE will be thrown from DeltaFilesMetricsReporter#mergeDeltaFilesStats.
