CheckpointConfiguration
import type { CheckpointConfiguration } from "https://aws-api.deno.dev/v0.4/services/kinesisanalyticsv2.ts?docs=full";
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 in the Apache Flink Documentation.
§Properties
Describes whether checkpointing is enabled for a Flink-based Kinesis Data Analytics application.
Note:
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.
Describes the interval in milliseconds between checkpoint operations.
Note:
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.
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.
Note:
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
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 in the Apache Flink Documentation.
Note:
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.
