DESCRIBE AGGREGATE. Lists all user-defined aggregates (UDAs) or shows the CQL definition for a specific UDA. Shows this output depending on the options selected: All user-defined aggregates (UDAs) in the current keyspace. All UDAs in the cluster when no keyspace is selected. · Query processing pipeline for interpreted Transact-SQL access to memory-optimized tables. As illustrated by the figure, the query processing pipeline remains mostly unchanged: The parser and algebrizer construct the query tree. The optimizer creates the execution plan. The query execution engine interprets the execution plan. · Aggregate Data. An aggregate data is the data that is the result of applying a process to combine data elements from different sources. The aggregate data is usually taken collectively or in summary form. In relational database technology, aggregate data refers to the values returned when one issues an aggregate function.

What is Data Aggregation?

 · Definition 2 (Aggregate graph queries) Aggregate graph queries (AGQs) are a class of graph queries that compute an aggregate function on the set of subgraphs that match the Boolean expression, i.e., an AGQ (Q(G,C) = Agg(GQ(G, C))) where Agg is an aggregate function. · One of the most common query types in DSPSs is a continuous aggregate query, which computes useful summary information (e.g., sum, count, average) over data streams. To process a continuous aggregate query, each source node periodically sends partial aggregates to the sink node, which then computes the final aggregates from them.A row of aggregate data can represent hundreds, thousands or even more atomic data records. When the data is aggregated, it can be queried quickly instead of requiring all of the processing cycles to access each underlying atomic data row and aggregate it in real time when it is queried or accessed.
