The BATCH function divides a scalar field’s values into specific ranges. Each range becomes a grouping field value, and objects contribute to the metric computation for the ranges for which it has values. The BATCH function’s first value must be a scalar field. The remaining values must be literal values compatible with the field’s type (text, timestamp, or numeric), and they must be given in ascending order. Example:This query counts messages grouped by specific ranges of the Size field from the shard named 2014‑06‑01. The ranges are divided at the given literal values: 100, 1000, 10000, and 100000. The lowest value implicitly creates an extra less than group; the highest value is open-ended and creates a greater than or equal to group. The query in the example above defines the following 5 groups:As shown above in the <100 group, if no selected object has a value that falls into one of the specified groups, that group is still returned: the group’s metric is 0 for the COUNT function and empty for all other metric functions. As with all grouped aggregate queries, a summary value is returned that applies the metric function across all groups.
