Subject Re: Spark for offline log processing/querying

Do you want to replace ELK by Spark? Depending on your queries you could do as you proposed.
However, many of the text analytics queries will probably be much faster on ELK. If your queries
are more interactive and not about batch processing then it does not make so much sense. I
am not sure why you plan to use Presto.
