Class CacheAllStreams

Namespace
ToSic.Eav.DataSources.Caching
Assembly
ToSic.Eav.DataSources.dll

Special DataSource which automatically caches everything it's given. It's Used to optimize queries, so that heavier calculations don't need to be repeated if another request with the same signature is used.
Internally it asks all up-stream DataSources what factors would determine their caching. So if part of the supplying DataSources would have a changed parameter (like a different filter), it will still run the full query and cache the results again.

Remarks

  • Changed in v15.05 to use the immutable convention
  • note that the above change is actually a breaking change, but since this is such an advanced DataSource, we assume it's not used in dynamic code.

Properties

CacheDurationInSeconds

How long to keep these streams in the cache. Default is 0 - meaning fall back to 1 day

[Configuration(Fallback = 0)]
public int CacheDurationInSeconds { get; }

Property Value

int

Out

Gets the Dictionary of Out-Streams. This is the internal accessor, as usually you'll use this["name"] instead.
In rare cases you need the Out, for example to list the stream names in the data source.

public override IReadOnlyDictionary<string, IDataStream> Out { get; }

Property Value

IReadOnlyDictionary<string, IDataStream>

A dictionary of named IDataStream objects, case insensitive

RefreshOnSourceRefresh

If a source-refresh should trigger a cache rebuild

[Configuration(Fallback = true)]
public bool RefreshOnSourceRefresh { get; }

Property Value

bool

ReturnCacheWhileRefreshing

Perform a cache rebuild async.

[Configuration(Fallback = false)]
public bool ReturnCacheWhileRefreshing { get; }

Property Value

bool
