[ aws . lakeformation ]



Submits a request to process a query statement.

This operation generates work units that can be retrieved with the GetWorkUnits operation as soon as the query state is WORKUNITS_AVAILABLE or FINISHED.

--query-planning-context (structure)

A structure containing information about the query plan.

CatalogId -> (string)

The ID of the Data Catalog where the partition in question resides. If none is provided, the Amazon Web Services account ID is used by default.

DatabaseName -> (string)

The database containing the table.

QueryAsOfTime -> (timestamp)

The time as of when to read the table contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId .

QueryParameters -> (map)

A map consisting of key-value pairs.

key -> (string)

value -> (string)

TransactionId -> (string)

The transaction ID at which to read the table contents. If this transaction is not committed, the read will be treated as part of that transaction and will see its writes. If this transaction has aborted, an error will be returned. If not set, defaults to the most recent committed transaction. Cannot be specified along with QueryAsOfTime .

JSON Syntax:

  "CatalogId": "string",
  "DatabaseName": "string",
  "QueryAsOfTime": timestamp,
  "QueryParameters": {"string": "string"
  "TransactionId": "string"

--query-string (string)

A PartiQL query statement used as an input to the planner service.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To process query statement

The following start-query-planning example submits a request to process a query statement.

aws lakeformation start-query-planning \
    --cli-input-json file://input.json

Contents of input.json:

    "QueryPlanningContext": {
        "CatalogId": "012345678901",
        "DatabaseName": "tpc"
    "QueryString": "select * from dl_tpc_household_demographics_gov where hd_income_band_sk=9"


    "QueryId": "772a273f-4a62-4cda-8d98-69615ee8be9b"

For more information, see Reading from and writing to the data lake within transactions in the AWS Lake Formation Developer Guide.


QueryId -> (string)

The ID of the plan query operation can be used to fetch the actual work unit descriptors that are produced as the result of the operation. The ID is also used to get the query state and as an input to the Execute operation.
