Hi Evelyn,
By "updates" are you referring to updating existing data that you already ingested? Or just adding in new data every day?
For adding new data, this is a core product feature and can be easily set up through the web console "Load Data" wizard screens. I've seen both daily and hourly data ingests done on a regular basis. Fyi the new MSQ ingestion is reported to work much faster than ingestion through the original "native" batch ingestion, so I suggest you try that out and use it as your primary ingestion mode if it works for you.
For updates, those can also be done but they require a bit more attention because they will replace all existing data within a time range. If that is what you want to do let me know and I can give you more info on it.
Thanks. John
