Transformation is converting data using special transformer functions.

and transform them.
A transformer can be run at both the metadata and data levels.
Data can only be transformed if the source and target are of different types.

Field

When activating a transfer, a transformation plan is made for the tables that
match the specified criteria.
Transformers are applied to the tables in the sequence specified in the list.

values will be used for calculating a hash to determine a shard.

Field	Description
tables	TablesFilter List of included and excluded tables
columns	ColumnsFilter List of included and excluded columns
shardsCount	string (int64) Number of shards

TableSplitterTransformer

A transfer splits the X table into multiple tables (X_1, X_2, ..., X_n) based on
data.
If a row was located in the X table before it was split, it is now in the X_i
table,
where i is determined by the column list and split string parameters.
Example:
If the column list has two columns, month of birth and gender, specified and the
split string states @,
information about an employee whose name is John and who was born on February
11, 1984,
from the Employees table will get to a new table named Employees@February@male.

Field	Description
tables	TablesFilter List of included and excluded tables
columns[]	string Specify the columns in the tables to be partitioned.
splitter	string Specify the split string to be used for merging components in a new table name.

FilterRowsTransformer

This filter only applies to transfers with queues (Logbroker or Apache Kafka®)
as a data source.
When running a transfer, only the strings meeting the specified criteria remain
in a changefeed.

Field	Description
tables	TablesFilter List of included and excluded tables.
filter	string Filtering criterion. This can be comparison operators for numeric, string, and Boolean values, comparison to NULL, and checking whether a substring is part of a string. Details here: https://yandex.cloud/en-ru/docs/data-transfer/concepts/data-transformation#append-only-sources. Deprecated: Use filters instead.
filters[]	string Data is transported if it satisfies at least one of filters. Consider that there is OR statement between filters. Each filter can be comparison operators for numeric, string, and Boolean values, comparison to NULL, and checking whether a substring is part of a string. Details in docs: https://yandex.cloud/en-ru/docs/data-transfer/concepts/data-transformation#append-only-sources.

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
createdAt	string (date-time) Creation timestamp. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	string (date-time) The time when the Operation resource was last modified. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
done	boolean If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	object Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	object The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

Status

The error result of the operation in case of failure or cancellation.

Field	Description
code	integer (int32) Error code. An enum value of google.rpc.Code.
message	string An error message.
details[]	object A list of messages that carry the error details.
