 SerDes serDes)

Method Details

retryStrategy

public StepConfig.Builder retryStrategy(RetryStrategy retryStrategy)

Sets the retry strategy for the step.

Parameters:

retryStrategy - the retry strategy to use, or null for default behavior

Returns:

this builder for method chaining

semantics

@Deprecated(forRemoval=true)
public StepConfig.Builder semantics(StepSemantics semantics)

Deprecated, for removal: This API element is subject to removal in a future version.

Use semanticsPerRetry(StepSemantics) instead. This method has incorrect behavior where AT_MOST_ONCE_PER_RETRY does not retry after step interruption.

Sets the delivery semantics for the step.

Parameters:

semantics - the delivery semantics to use, defaults to AT_LEAST_ONCE_PER_RETRY if not specified

Returns:

this builder for method chaining

semanticsPerRetry

public StepConfig.Builder semanticsPerRetry(StepSemantics semanticsPerRetry)

Sets the delivery semantics per retry for the step.

If set, this takes precedence over semantics(StepSemantics).

Parameters:

semanticsPerRetry - the delivery semantics to use

Returns:

this builder for method chaining

serDes

public StepConfig.Builder serDes(SerDes serDes)

Sets a custom serializer for the step.

If not specified, the step will use the default SerDes configured for the handler. This allows per-step customization of serialization behavior, useful for steps that need special handling (e.g., custom date formats, encryption, compression).

Parameters:

serDes - the custom serializer to use, or null to use the default

Returns:

this builder for method chaining

build

public StepConfig build()

Builds the StepConfig instance.

Returns:

a new StepConfig with the configured options
