// ProtoTableManager is the instance of TableManager intended to be used
// in the common case of storing string-to-proto tables (alongside
// KeyValueData<T> and KeyValueTable<T>).
//
// End-to-end use:
// 1. Initialize a database with sql::Database::Open.
// 2. Initialize a ProtoTableManager on top of this database.
// 3. For each table, construct a pair of KeyValueTable and KeyValueData
// on the main sequence; initialize the KeyValueData on the database sequence.
// 4. Now, initialization is finished and the KeyValueData objects can be
// used (on the main thread) for get/put/delete operations against the database.
//
// TODO(crbug.com/40671040): This interface is a bit complex and could do with
// a refactor.
