NAME

Paws::KinesisAnalyticsV2::CheckpointConfiguration

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::KinesisAnalyticsV2::CheckpointConfiguration object:

  $service_obj->Method(Att1 => { CheckpointingEnabled => $value, ..., MinPauseBetweenCheckpoints => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::KinesisAnalyticsV2::CheckpointConfiguration object:

  $result = $service_obj->Method(...);
  $result->Att1->CheckpointingEnabled

DESCRIPTION

Describes an application's checkpointing configuration. Checkpointing is the process of persisting application state for fault tolerance. For more information, see Checkpoints for Fault Tolerance (https://ci.apache.org/projects/flink/flink-docs-release-1.8/concepts/programming-model.html#checkpoints-for-fault-tolerance) in the Apache Flink Documentation (https://ci.apache.org/projects/flink/flink-docs-release-1.8/).

ATTRIBUTES

CheckpointingEnabled => Bool

Describes whether checkpointing is enabled for a Flink-based Kinesis Data Analytics application.

If "CheckpointConfiguration.ConfigurationType" is "DEFAULT", the application will use a "CheckpointingEnabled" value of "true", even if this value is set to another value using this API or in application code.

CheckpointInterval => Int

Describes the interval in milliseconds between checkpoint operations.

If "CheckpointConfiguration.ConfigurationType" is "DEFAULT", the application will use a "CheckpointInterval" value of 60000, even if this value is set to another value using this API or in application code.

REQUIRED ConfigurationType => Str

Describes whether the application uses Kinesis Data Analytics' default checkpointing behavior. You must set this property to "CUSTOM" in order to set the "CheckpointingEnabled", "CheckpointInterval", or "MinPauseBetweenCheckpoints" parameters.

If this value is set to "DEFAULT", the application will use the following values, even if they are set to other values using APIs or application code:

CheckpointingEnabled: true
CheckpointInterval: 60000
MinPauseBetweenCheckpoints: 5000

MinPauseBetweenCheckpoints => Int

Describes the minimum time in milliseconds after a checkpoint operation completes that a new checkpoint operation can start. If a checkpoint operation takes longer than the "CheckpointInterval", the application otherwise performs continual checkpoint operations. For more information, see Tuning Checkpointing (https://ci.apache.org/projects/flink/flink-docs-release-1.8/ops/state/large_state_tuning.html#tuning-checkpointing) in the Apache Flink Documentation (https://ci.apache.org/projects/flink/flink-docs-release-1.8/).

If "CheckpointConfiguration.ConfigurationType" is "DEFAULT", the application will use a "MinPauseBetweenCheckpoints" value of 5000, even if this value is set using this API or in application code.
