Amazonka.AppSync.Types.SyncConfig

Description

 
Synopsis

Documentation

data SyncConfig Source #

Describes a Sync configuration for a resolver.

Contains information on which Conflict Detection as well as Resolution strategy should be performed when the resolver is invoked.

See: newSyncConfig smart constructor.

Constructors

SyncConfig' 

Fields

  • conflictHandler :: Maybe ConflictHandlerType

    The Conflict Resolution strategy to perform in the event of a conflict.

    • OPTIMISTIC_CONCURRENCY: Resolve conflicts by rejecting mutations when versions do not match the latest version at the server.
    • AUTOMERGE: Resolve conflicts with the Automerge conflict resolution strategy.
    • LAMBDA: Resolve conflicts with a Lambda function supplied in the LambdaConflictHandlerConfig.
  • conflictDetection :: Maybe ConflictDetectionType

    The Conflict Detection strategy to use.

    • VERSION: Detect conflicts based on object versions for this resolver.
    • NONE: Do not detect conflicts when executing this resolver.
  • lambdaConflictHandlerConfig :: Maybe LambdaConflictHandlerConfig

    The LambdaConflictHandlerConfig when configuring LAMBDA as the Conflict Handler.
