See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-column-statistics-for-partition
[--catalog-id <value>]
--database-name <value>
--table-name <value>
--partition-values <value>
--column-names <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--catalog-id (string)

The ID of the Data Catalog where the partitions in question reside. If none is supplied, the AWS account ID is used by default.

--database-name (string)

The name of the catalog database where the partitions reside.

--table-name (string)

The name of the partitions' table.

--partition-values (list)

A list of partition values identifying the partition.

(string)

Syntax:

"string" "string" ...

--column-names (list)

A list of the column names.

(string)

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
