AWS::DMS::Endpoint MySqlSettings - AWS CloudFormation
SyntaxProperties

AWS::DMS::Endpoint MySqlSettings

Provides information that defines a MySQL endpoint. This information includes the output format of records applied to the endpoint and details of transaction and control table data information. For information about other available settings, see Extra connection attributes when using MySQL as a source for AWS DMS and Extra connection attributes when using a MySQL-compatible database as a target for AWS DMS in the AWS Database Migration Service User Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "AfterConnectScript" : String,
  "CleanSourceMetadataOnMismatch" : Boolean,
  "EventsPollInterval" : Integer,
  "MaxFileSize" : Integer,
  "ParallelLoadThreads" : Integer,
  "SecretsManagerAccessRoleArn" : String,
  "SecretsManagerSecretId" : String,
  "ServerTimezone" : String,
  "TargetDbType" : String
}

Properties

AfterConnectScript

Specifies a script to run immediately after AWS DMS connects to the endpoint. The migration task continues running regardless if the SQL statement succeeds or fails.

For this parameter, provide the code of the script itself, not the name of a file containing the script.

Required: No

Type: String

Update requires: No interruption

CleanSourceMetadataOnMismatch

Cleans and recreates table metadata information on the replication instance when a mismatch occurs. For example, in a situation where running an alter DDL on the table could result in different information about the table cached in the replication instance.

Required: No

Type: Boolean

Update requires: No interruption

EventsPollInterval

Specifies how often to check the binary log for new changes/events when the database is idle. The default is five seconds.

Example: eventsPollInterval=5;

In the example, AWS DMS checks for changes in the binary logs every five seconds.

Required: No

Type: Integer

Update requires: No interruption

MaxFileSize

Specifies the maximum size (in KB) of any .csv file used to transfer data to a MySQL-compatible database.

Example: maxFileSize=512

Required: No

Type: Integer

Update requires: No interruption

ParallelLoadThreads

Improves performance when loading data into the MySQL-compatible target database. Specifies how many threads to use to load the data into the MySQL-compatible target database. Setting a large number of threads can have an adverse effect on database performance, because a separate connection is required for each thread. The default is one.

Example: parallelLoadThreads=1

Required: No

Type: Integer

Update requires: No interruption

SecretsManagerAccessRoleArn

The full Amazon Resource Name (ARN) of the IAM role that specifies AWS DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the AWS Secrets Manager secret that allows access to the MySQL endpoint.

Note

You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both.

For more information on creating this SecretsManagerSecret, the corresponding SecretsManagerAccessRoleArn, and the SecretsManagerSecretId that is required to access it, see Using secrets to access AWS Database Migration Service resources in the AWS Database Migration Service User Guide.

Required: No

Type: String

Update requires: No interruption

SecretsManagerSecretId

The full ARN, partial ARN, or display name of the SecretsManagerSecret that contains the MySQL endpoint connection details.

Required: No

Type: String

Update requires: No interruption

ServerTimezone

Specifies the time zone for the source MySQL database.

Example: serverTimezone=US/Pacific;

Note: Do not enclose time zones in single quotes.

Required: No

Type: String

Update requires: No interruption

TargetDbType

Specifies where to migrate source tables on the target, either to a single database or multiple databases. If you specify SPECIFIC_DATABASE, specify the database name using the DatabaseName parameter of the Endpoint object.

Example: targetDbType=MULTIPLE_DATABASES

Required: No

Type: String

Update requires: No interruption
