delete-endpoint¶

Description¶

Deletes the specified endpoint.

Note

All tasks associated with the endpoint must be deleted before you can delete the endpoint.

Synopsis¶

  delete-endpoint
--endpoint-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--endpoint-arn (string)

The Amazon Resource Name (ARN) string that uniquely identifies the endpoint.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

BucketName -> (string)

The name of the S3 bucket.

CompressionType -> (string)

An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don’t use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

EncryptionMode -> (string)

The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS . To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

s3:CreateBucket

s3:ListBucket

s3:DeleteBucket

s3:GetBucketLocation

s3:GetObject

s3:PutObject

s3:DeleteObject

s3:GetObjectVersion

s3:GetBucketPolicy

s3:PutBucketPolicy

s3:DeleteBucketPolicy

ServerSideEncryptionKmsKeyId -> (string)

If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.

Here is a CLI example: ``aws dms create-endpoint –endpoint-identifier value –endpoint-type target –engine-name s3 –s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

DataFormat -> (string)

The format of the data that you want to use for output. You can choose one of the following:

csv : This is a row-based file format with comma-separated values (.csv).

parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.

EncodingType -> (string)

The type of encoding you are using:

RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.

PLAIN doesn’t use encoding at all. Values are stored as they are.

PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.

DictPageSizeLimit -> (integer)

The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

RowGroupLength -> (integer)

The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

DataPageSize -> (integer)

The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

ParquetVersion -> (string)

The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

EnableStatistics -> (boolean)

A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

IncludeOpForFullLoad -> (boolean)

A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.

Note

AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

Note

This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .

CdcInsertsOnly -> (boolean)

A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .

Note

AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can’t both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

TimestampColumnName -> (string)

A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

Note

AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

ParquetTimestampInMillisecond -> (boolean)

A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

Note

AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.

Note

AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

CdcInsertsAndUpdates -> (boolean)

A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .

Note

AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can’t both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

DmsTransferSettings -> (structure)

The settings in JSON format for the DMS transfer type of source endpoint.

Possible settings include the following:

ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.

BucketName - The name of the S3 bucket to use.

CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don’t use this value.

Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string

JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

Shows the partition value within the Kinesis message output, unless the partition type is schema-table-type . The default is False .

PartitionIncludeSchemaTable -> (boolean)

Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kinesis shards. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same shard, which causes throttling. The default is False .

IncludeTableAlterOperations -> (boolean)
