> 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.
