Inheritance

object

Namespace: Umbraco.Cms.Core

Assembly: Umbraco.Core.dll

Syntax

public class CacheSyncService : ICacheSyncService

Constructors

CacheSyncService(IMachineInfoFactory, CacheRefresherCollection, ICacheInstructionService)

Initializes a new instance of the CacheSyncService class.

Declaration

public CacheSyncService(IMachineInfoFactory machineInfoFactory, CacheRefresherCollection cacheRefreshers, ICacheInstructionService cacheInstructionService)

Parameters

Type	Name	Description
IMachineInfoFactory	machineInfoFactory	The factory for getting machine information.
CacheRefresherCollection	cacheRefreshers	The collection of cache refreshers.
ICacheInstructionService	cacheInstructionService	The service for processing cache instructions.

Methods

SyncAll(CancellationToken)

Synchronizes all caches including both isolated caches and published content caches.

Declaration

public void SyncAll(CancellationToken cancellationToken = default)

Parameters

Type	Name	Description
CancellationToken	cancellationToken	A token to monitor for cancellation requests.

Remarks

This method clears all isolated caches (repositories and services) and published content caches (IPublishedContentCache, route caching, etc.) to ensure complete cache consistency across the cluster.

SyncInternal(CancellationToken)

Synchronizes only isolated caches without affecting the published content cache layer.

Declaration

public void SyncInternal(CancellationToken cancellationToken)

Parameters

Type	Name	Description
CancellationToken	cancellationToken	A token to monitor for cancellation requests.

Remarks

This method clears only the isolated caches used by repositories and services, leaving the published content cache layer intact. During synchronization, repositories reload data from the database while temporarily bypassing version checking to prevent recursive sync attempts.
