Abstract
Data analytics is performed on a distributed document storage database by receiving a request for initiating a data analytics job; collecting statistics from the database in response to the request; using the statistics to estimate a first cost for merging an incremental data update for the job into a first resilient distributed dataset; using the statistics to estimate a second cost for newly creating a second resilient distributed dataset for the job; when the first cost is less than the second cost, reading data updates from the database and merging the data updates into the first resilient distributed dataset; and when the first cost is not less than the second cost, newly creating the second resilient distributed dataset by reading all documents from the database.
