title: Is there any way to connect MongoDB to Druid?
body: <p>My organisation have MongoDB which stores application based time-series data. Now we are trying to create a data pipeline for analytics and visualisation. Due to  time-series data we plan to use Druid as intermediate storage where we can do the required transformation and then use Apache Superset to visualise. Is there any way to migrate required data (not only updates) from MongoDB to Druid? </p>
  
  <p>I was thinking about Apache Kafka but from what I have read, I understood that it will work better only to stream the changes happening in topics (topic associated with tables) which already exists in MongoDB and Druid. But what if there is a table of at least 100,000 records which exists only in MongoDB and first I wish to push whole table to Druid, will Kafka work in this scenario?</p>
