   A DoFn that performs asynchronous lookup using the provided client. Lookup requests may be deduplicated.

2.  abstract class BaseAsyncDoFn[Input, Output, Resource, Future] extends DoFnWithResource[Input, Output, Resource] with Base[Future, Output]

   A DoFn that handles asynchronous requests to an external service.

3.  abstract class BaseAsyncLookupDoFn[Input, Output, Client, Future, TryWrapper] extends DoFnWithResource[Input, KV[Input, TryWrapper], Pair[Client, Cache[Input, Output]]] with Base[Future, Output]

4.  class BatchDoFn[InputT] extends DoFn[InputT, Iterable[InputT]]

   Batches input into a desired batch size.

   Batches input into a desired batch size.

   Elements are buffered until there are enough elements for a batch, at which point they are emitted to the output PCollection

   Windows are preserved (batches contain elements from the same window). Batches are not spanning over bundles. Once a bundle is finished, the batch is emitted even if not full. This function can only batch 10 parallel windows. If new element comes from an 11th window, the bigger batch will be emitted to give room for this new element.

    DoFn which will rate limit the number of elements processed per second.

    Used to rate limit throughput for a job writing to a database or making calls to external services. The limit is applied per worker and should be used with a fixed/max num workers. Having RateLimiterDoFn(1000) and 20 workers means your total rate will be 20000.
