describe-replication-tasks
is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate
argument.
When using --output text
and the --query
argument on a paginated response, the --query
argument must extract data from the results of the following query expressions: ReplicationTasks

--filters
(list)
Filters applied to replication tasks.
Valid filter names: replication-task-arn | replication-task-id | migration-type | endpoint-arn | replication-instance-arn
(structure)
Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular
Describe*
call or similar operation. Filters are used as an optional parameter for certain API operations.Name -> (string)
The name of the filter as specified for aDescribe*
or similar operation.Values -> (list)
The filter value, which can specify one or more values used to narrow the returned results.
(string)
Shorthand Syntax:
Name=string,Values=string,string ...
JSON Syntax:
[
{
"Name": "string",
"Values": ["string", ...]
}
...
]
--without-settings
| --no-without-settings
(boolean)
An option to set to avoid returning information about settings. Use this to reduce overhead when setting information is too large. To use this option, choosetrue
; otherwise, choosefalse
(the default).
--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.
--starting-token
(string)
A token to specify where to start paginating. This is the
NextToken
from a previously truncated response.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--page-size
(integer)
The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.
For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--max-items
(integer)
The total number of items to return in the command's output. If the total number of items available is more than the value specified, a
NextToken
is provided in the command's output. To resume pagination, provide theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
response element directly outside of the AWS CLI.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--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.
--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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.
--output
(string)
The formatting style for command output.
--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.
--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.
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 describe a replication task
The following describe-replication-tasks
example describes current replication tasks.

CreateReplicationTask
operation.ReplicationTaskIdentifier -> (string)
The user-assigned replication task identifier or name.
Constraints:
- Must contain 1-255 alphanumeric characters or hyphens.
- First character must be a letter.

"moving"
– The task is being moved in response to running the `MoveReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_MoveReplicationTask.html`__ operation."creating"
– The task is being created in response to running the `CreateReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_CreateReplicationTask.html`__ operation."deleting"
– The task is being deleted in response to running the `DeleteReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_DeleteReplicationTask.html`__ operation."failed"

https://docs.aws.amazon.com/dms/latest/APIReference/API_MoveReplicationTask.html`__ operation."modifying"
– The task definition is being modified in response to running the `ModifyReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_ModifyReplicationTask.html`__ operation."ready"
– The task is in aready
state where it can respond to other task operations, such as `StartReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTask.html`__ or `DeleteReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_DeleteReplicationTask.html`__ ."running"
– The task is performing a database migration in response to running the `StartReplicationTask
https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTask.html`__ operation."starting"

https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessmentRun.html`__ enables you to specify a variety of premigration task assessments in addition to data type compatibility. These assessments include ones for the validity of primary key definitions and likely issues with database migration performance, among others.LastFailureMessage -> (string)
