    • The DynamicSchemaAPI provides methods to clear the various caches used by the dynamic schema implementation.

    You must have the dynamic_schema_writer role to execute any of the clear() methods.

    Remarque :
    You shouldn't need to call the clear() methods in a production environment. Use these methods when you are troubleshooting your implementation if you think there is a possible caching problem causing stale data.

    See also Dynamic Schema.

    DynamicSchemaAPI - clearDynamicCategoryCache()

    Clears the entire dynamic category cache (DynamicCategoryCache).

    DynamicCategoryCache is the internal in-memory cache of all dynamic categories. If you observe issues with stale category data, use this method to clear the cache.

    Tableau 2. Returns
    Type Description
    None

    The following code example shows how to call this method.

    var api = DynamicSchemaAPI.get();
api.clearDynamicCategoryCache();

    DynamicSchemaAPI - clearDynamicChoiceSetCache()

    Clears the entire dynamic choice set cache (DynamicChoiceSets).

    DynamicChoiceSets is the internal in-memory cache of all dynamic choice sets. If you observe issues with stale choice sets data, use this method to clear the cache.
