Excessive memory being used in pipelines with deeply nested documents

XMLWordPrintableJSON

    • ALL
    • Query 2020-10-05, Query 2020-10-19

      Included are memory allocations flamegraphs showing a pair of aggregations with deeply nested documents and $redact  using 35GB of memory or 18.5GB each.

      I do not have the exact aggregation and example document(s) to reproduce this issue, but I believe deeply nested documents with $redact should show similar issues.
