.split() operator does not tolerate duplicate keys,
i.e. the Seq you provide it must not contain records
that have the same key(record).
However, checking for duplicate keys can get expensive when splitting very large lists, so this setting can be used to disable the checks.
When warnings are enabled, YOUR CODE WILL STILL BREAK if the .split() operator encounters duplicate keys, but it will first print a warning in the browser console listing the duplicate keys at fault.
We enable this setting by default to aid in debugging. As the end user, you might want to disable this either globally or for specific .split() usages to improve performance on very large lists.
#TODO[Docs]: Add a short section to the docs about this.
#TODO: Add more granular control later, if there is demand for that. For example, we could instruct Airstream to skip duplicate keys, or to raise an exception if a duplicate happens. In the latter case perhaps we could do that by catching the right exception, without the overhead of checking for duplicates. But not sure how bulletproof that logic would be.
