Description

Currently TableInfo for all tables in a colocated database are stored in the superblock of the parent tablet. This is a serialized proto file where the entire file is read/written as a single unit.
As a result of this, as the number of tables increases, the size of the file increases and therefore the latency of the operation also increases.

Proposal is to decouple the table schema from tablet metadata so that adding/removing tables results in a incremental update to the metadata as opposed to a full file update.
