Introduce Histogram grouping function for bucketing/grouping data based
on a given range. Both date and numeric histograms are supported using
the appropriate range declaration (numbers vs intervals).
SELECT HISTOGRAM(number, 50) AS h FROM index GROUP BY h
SELECT HISTOGRAM(date, INTERVAL 1 YEAR) AS h FROM index GROUP BY h
In addition add multiply operator for Intervals
Add docs for intervals and histogram
Fix#36509
Extend SHOW TABLES, DESCRIBE and SHOW COLUMNS to support table
identifiers not just SQL LIKE pattern.
This allows both Elasticsearch-style multi-index patterns and SQL LIKE.
To disambiguate between the two (as the " vs ' can be easy to miss),
the grammar now requires LIKE keyword as a prefix for all LIKE-like
patterns.
Also added some docs comparing the two types of patterns.
