Description

Sorted Index Storage has a binary storage format that is subject to change in the future. Though index schema is immutable and any change to it leads to index being rebuilt, it should be possible to update the storage format without rebuilding. It means that there should be some kind of a versioning mechanism, so that IndexKey serialization format can be changed in a backwards-compatilbe way.
