> Key: KAFKA-9404
> URL: https://issues.apache.org/jira/browse/KAFKA-9404
> Project: Kafka
> Issue Type: Improvement
> Reporter: David Mollitor
> Priority: Trivial
>
> Since this collection is going to be bulk-built once and not modified, better
> to use an {{ArrayList}} since its memory requirements are smaller and it is
> much faster here... just instantiate the internal array once and fill it...
> as opposed to {{LinkedList}} that must build the nodes for each item
> inserted. {{ArrayList}} is also faster for iteration.
