> We need to prepare the store (and its implementations) for index building.
> We need the ability to save and retrieve the row ID for which we want to build an index.
> I propose the following design:
> {code:java}
> public interface IndexStorage {
>     ...
>     /**
>      * Returns the row ID for which the index needs to be built, {@code null} means that the index building has completed.
>      *
>      * <p>If index building has not started yet, it will return {@link RowId#lowestRowId(int)}.
>      *
>      * @throws StorageException If failed to get the row ID.
>      */
>     @Nullable RowId getRowIdToBuilt();
>     /**
>      * Sets the row ID for which the index needs to be built, {@code null} means that the index is built.
>      *
>      * @apiNote This method <b>must</b> always be called inside the corresponding partition's
>      *     {@link org.apache.ignite.internal.storage.MvPartitionStorage#runConsistently} closure.
>      * 
>      * @param rowId Row ID.
>      * @throws StorageException If failed to set the row ID.
>      */
>     void setRowIdToBuilt(@Nullable RowId rowId);
> }
> {code}
