Once datasets have been delivered to the S3 bucket, they take some time to ingest. The ingestion process runs every few hours, and depending on the size of the file, and the current ingestion queue, the datasets can be visible on the platform between 4 and 24 hours after the ingestion process has begun.
To check whether the files have been ingested, please look in the S3 bucket for the status files (.fail, .success), which show that ingestion has taken place.
