However, I'm getting an error because the new version of react-apollo does not export this.

阅读更多关于 Weighted Average for nested aggregation in Elastic Search

问题 I am trying to obtain the weighted average by aggregating a nested list. Each document has details of a single student, and the subjects vary across each student and each subject has different weights. I am trying to calculate the weighted average subject-wise.

问题 We've been having this issue in prod for the past few weeks. Every few days, the number of connections to our compose.io Mongo db spikes to nearly 5000, which is the connection limit.
