1024 transaction per bucket limit

With respect to the 1024 limit per bucket documented here: https://docs.couchbase.com/server/6.5/learn/data/transactions.html

Presumably that's a soft limit and can be increased? That limit would prevent us from using this feature given how we use buckets. Ideally we'd want to know that limit is horizontally scalable in the same way the bucket itself is - that would then create a manageable situation allowing us to add more hardware and rebalance in the case where we ran into that limit.
