Automatically Caching Data
Automatically caching data is useful when you do not want to rebuild the cache for each query. When you query data for the first time, the component automatically initializes and builds a cache in the background. When AutoCache = true, the component uses the cache for subsequent query executions, resulting in faster response times.
Configuring Automatic Caching
Caching the SampleTable_1 Table
The following example caches the SampleTable_1 table in the file specified by the CacheLocation property of the connection string.
SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = 'Bob'
Common Use Case
A common use for automatically caching data is to improve driver performance when making repeated requests to a live data source, such as building a report or creating a visualization. With auto caching enabled, repeated requests to the same data may be executed in a short period of time, but within an allowable tolerance (CacheTolerance) of what is considered "live" data.
