Description
In table system_distributions.cdc_streams_descriptions_v2 in our scylla db one of generations gives empty streams i.e. generation exists in cdc_generations_timestamps, but when querying cdc_streams_descriptions_v2 with where time = 'missing timestamp' gives 0 rows.
Cdc does not run, gives IllegalArgumentException, because https://github.com/scylladb/scylla-cdc-java/blob/master/scylla-cdc-base/src/main/java/com/scylladb/cdc/model/master/GenerationMetadata.java#L21
Is it possible to skip empty generations or provide start date that is not equal to Date(0) - epoch start
