Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:

A common use of the aggregate transformation is removing or identifying duplicate entries in source data. This process is known as deduplication. Based upon a set of group by keys, use a heuristic of your choosing to determine which duplicate row to keep. Common heuristics are first (), last (), max (), and min ().

Aggregate functions. Aggregate functions summarize the values from each event to create a single, meaningful value. Common aggregate functions include Average, Count, Minimum, Maximum, Standard Deviation, Sum, and Variance. Most aggregate functions are used with numeric fields.
