consume operator
Learn how to use the consume operator to consume the tabular data stream handed to the 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.
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.)
Syntax
consume [decodeblocks = DecodeBlocks]
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
| DecodeBlocks | bool | 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. |
