             Summary: SQL Joins Metrics
                 Key: IGNITE-4757
                 URL: https://issues.apache.org/jira/browse/IGNITE-4757
             Project: Ignite
          Issue Type: Task
            Reporter: Denis Magda


SQL queries monitoring part has to be improved. Suggest to add the metrics below.

Per-query metrics. Total history size is defined by {{CacheConfiguration.getQueryDetailMetricsSize()}}:
* if a query was executed in the collocated or non-collocated mode. Three results are valid:
collocated, non-collocated, simple query (no joins).
* non-collocated query: size of the data exchanged between the nodes to complete a join.
* non-collocated query: did a query do broadcast or unicast to get data needed to complete
a join.
* non-collocated and collocated query: a part of the time spent joining the data.

CacheMetrics:
* an average number of executed SQL queries (collocated, non-collocated, simple query (no
joins)).
