Bucket / item index space not the best split?

Currently there can be 64K buckets and 16M items per bucket. If we'd like to use this as a storage backend for txs, 16M might be on the low end (:scream:) but 64K power-of-2 buckets is insane. Perhaps we could move 4 more bits over and have 8K buckets and 256M items?

Even with linear buckets, 8K seems like never fillable

Don't forget that you are also required to maintain the index (in memory) on the app-side too.. But sure, we can move 4 bits over.

Yeah, my thought was to make that configurable, not only "allow" power-of-2

Moving 4 bites over makes it 4K, not 8K, buckets and 256M items
