Review comment:
Is there a guarantee that at least one element will be in the elementsBag iterator or is there a chance for a NoSuchElementsException on the `next()` call?

Would you move the comments about how a method works, or what it does, to the method definition please?

Please add a comment. It would also be beneficial to name this variable with a unit like `batchSizeBytes`.

Review comment:
See my earlier comment about moving configuration exceptions like this to pipeline construction time. Doing so will give earlier feedback to the user and avoid having to spin up workers and processing part of the pipeline before running into a configuration issue.

Review comment:
An incorrect configuration should result in an exception at pipeline construction time if possible. The sooner an exception can be raised to the user the better (e.g. pipeline construction vs. pipeline runtime).
A couple options are,
1. Add precondition checks into the Builder for the AutoValue. You could do this by implementing your own `public DLPDeidentifyText build()` method the checks preconditions and then calls a generated `autoBuild` method.
2. Add precondition checks into the constructor of the DoFn.

Review comment:
Nit: Can you move this to the first line of the if block to avoid splitting the code like this? Also it would be nice to have the unit in the log message for the bufferSize (e.g bytes).

Review comment:
Since the delimiter is configurable, what about dropping the 'csv'? You could add details in the comments as to where the delimiter applies and the default value.

Review comment:
Having the units in the name is helpful when the type is non-descriptive. Where did this number come from?

It would be helpful if these abstract methods, and possibly those in the builder, had comments.
