This patch introduces a GroupByStrategy concept and two strategies: "v1"
is the current groupBy strategy and "v2" is a new one. It also introduces
a merge buffers concept in DruidProcessingModule, to try to better
manage memory used for merging.
Both of these are described in more detail in #2987.
There are two goals of this patch:
1. Make it possible for historical/realtime nodes to return larger groupBy
result sets, faster, with better memory management.
2. Make it possible for brokers to merge streams when there are no order-by
columns, avoiding materialization.
This patch does not do anything to help with memory management on the broker
when there are order-by columns or when there are nested queries. That could
potentially be done in a future patch.
* docs: replace OR by AND inside topnquery docs about multi value dimensions
* docs: replace OR by AND inside groupby docs about multi value dimensions
* Cleanup the base lookup cluster wide config docs
* Add better examples in lookups-cached-global.md
* Use actual valid stock lookups
* Fixed maps with :
* Add mix of lookups
* Better examples in extension
* Remove unneeded namespace requirement
* Add extra line space
* Add link to lookup tiers
* Renamed header
* Async lookups-cached-global by default
* Also better lookup docs
* Fix test timeouts
* Fix timing of deserialized test
* Fix problem with 0 wait failing immediately
There is no such thing as a "Java aggregator" in Druid from a user's point of view, there are just native aggregator that happen to be implemented in Java.
- Make redirects for old links based on _redirects.json
- Replace #{DRUIDVERSION} tokens in docs with current version
- Allow origins named something other than "origin"
- Can use either s3cmd or awscli, depending on availability
* support LookupReferencesManager registration of namespaced lookup and eliminate static configurations for lookup from namespecd lookup extensions
- druid-namespace-lookup and druid-kafka-extraction-namespace are modified
- However, druid-namespace-lookup still has configuration about ON/OFF
HEAP cache manager selection, which is not namespace wide
configuration but node wide configuration as multiple namespace shares
the same cache manager
