    How does this handle gaps in the offsets in the source partitions?:

    + *

    + * We track per record acknowledgement, by only storing the offsets of records OF WHICH WE'VE RECEIVED + * through {@link KafkaConsumer#poll} calls. + *

    + * This is as explicitly opposed to looking at the lowest offset we've polled, and synthetically creating a list of + * EXPECTED offsets from the range from it to the highest polled. If we were to construct this offset range + * synthetically like this, then we would need to expect to process/receive records which might not exist, for + * whatever reason, usually due to compaction. + *

    + * Instead, the offsets tracked are only determined from the records we've given to process from the broker - we + * make no assumptions about which offsets exist. This way we don't have to worry about gaps in the offsets. Also, a + * nice outcome of this is that a gap in the offsets is effectively the same as, as far as we're concerned, an + * offset which has succeeded - because either way we have no action to take. *

    * This is independent of the actual queued {@link WorkContainer}s. This is because to start with, data about * incomplete offsets come from the encoded metadata payload that gets committed along with the highest committable - * offset ({@link #getOffsetHighestSequentialSucceeded()}). They are not always in sync. + * offset ({@link #getOffsetHighestSequentialSucceeded()}) and so we don't yet have ConsumerRecord's for those + * offsets until we start polling for them. And so they are not always in sync. *

    + *

    Concurrency:

    *

    * Needs to be concurrent because, the committer requesting the data to commit may be another thread - the broker * polling sub system - {@link BrokerPollSystem#maybeDoCommit}. The alternative to having this as a concurrent * collection, would be to have the control thread prepare possible commit data on every cycle, and park that data * so that the broker polling thread can grab it, if it wants to commit - i.e. the poller would not prepare/query - * the data for itself.
