34 * This activator is used to initialize and terminate the connection pool to one or more providers.
36 * The CDP abstraction layer supports multiple types of providers, with each provider supporting multiple tenants. The
37 * "connection" to a specific tenant on a specific provider is represented by a "context" object. These context objects
38 * are authenticated to a specific tenant on the provider, but can be reused from one request to another. Contexts are
39 * slow to set up and are resource intensive, so they are cached. However, the contexts for a specific tenant on a
40 * specific provider must be cached separately.
43 * Activation of the bundle creates an empty cache which is organized first by provider type, then by tenant name, with
44 * the contents being an empty pool of contexts for that provider/tenant combination. The pool is created on first use,
45 * and retained for as long as the bundle is active.
48 * When the bundle is deactivated, the cache is torn down with all contexts being closed.
