Hi,

Can someone give a opinion on aggregation performance in mongoDB vs Elastic search.

Thanks already.

What do you exactly mean by "performance" - time? space? min/max? average? throughput?

Can you give an example what aggregation you talk about?

What is a "one level" aggregation? Can you give an example so I understand what you are talking about?

What time performance do you mean? Latency? Overall search time? Average time? Time per search? Search Throughput?
