The key difference can be found in the Queueable Apex documentation: Similar to future jobs, queueable jobs don’t process batches, and so the number of processed batches and the number of total batches are always zero. Using non-primitive types. 1. Why is it so? Queuable Apex logic in Constructor or Execute Method. One approach you could take (this is fairly architecture-dependent) is a chained Queueable. When you will consider each instance of queuable job as a single transaction, all limits will be clear to you. The problem is that your anonymous Apex only exists for the transaction it was created in.

Queueable apex is similar to future methods, wherein your future method is queued within a server queue. This is a somewhat poorly chosen example because the same task could be done synchronously without Queuable. Previously, a queueable job could make a web service callout, but additional chained jobs that made callouts would throw exceptions.

Finalizer interface, it enables us to attach actions to asynchronous Apex jobs using the Queueable framework. 0. However, once the flex queue is full every attempt to execute another batch will bomb out with a limits violation.
