consume operator

Consumes the tabular data stream handed to the operator.

The consume operator is mostly used for triggering the query side-effect without actually returning the results back to the caller.

T | consume

Syntax

consume [decodeblocks = DecodeBlocks]

Arguments

• DecodeBlocks: A constant Boolean value. If set to true, or if the request property perftrace is set to true, the consume operator won't just enumerate the records at its input, but actually force each value in those records to be decompressed and decoded.

The consume operator can be used for estimating the cost of a query without actually delivering the results back to the client. (The estimation isn't exact for various reasons; for example, consume is calculated distributively, so T | consume won't transmit the table's data between the nodes of the cluster.)
