74b6a292d5 Use time.Duration instead of nanoseconds for constants 2019-09-13 07:31:07 +00:00
Bryan Boreham
b5376facf2 Cache merged groups of reports, to reduce the number we handle in parallel 
Previously we would merge all reports in a 15-second window.
Now we use a 'quantum' of 3 seconds, similar to the single-user app.

E.g. a 30-node cluster will have 150 individual reports over 15
seconds, but the new code will merge 5 pre-merged reports plus 20-ish
very recent individual ones.

This limits the max heap size used for deserialising, since we only do
3 seconds at once per instance.

Individual reports are still put into the cache, but should get
displaced by the pre-merged ones under LRU.

4c74f8b1cf Add metrics for report size and count per tenant 
In a multitenant system it is useful to be able to drill into which
tenants have the most or biggest reports.

1706746a32 Faster report merging through mutating objects 
When we know we have the only reference to a Report or Node object we
can avoid copying the data to change it. Add "Unsafe" variants of
various Merge operations which mutate the receiver, and a new Merger
which takes advantage of them.
