	// ErrEnqueueMessageConflict is returned when a message with the same ID already exists in the queue. This is
	// possible when there are concurrent writes to the queue because we enqueue a message using two queries:

func (*HistoryStore) ForkHistoryBranch added in v1.13.0 

func (h *HistoryStore) ForkHistoryBranch(
	ctx context.Context,
	request *p.InternalForkHistoryBranchRequest,
) error

ForkHistoryBranch forks a new branch from an existing branch Note that application must provide a void forking nodeID, it must be a valid nodeID in that branch. A valid forking nodeID can be an ancestor from the existing branch. For example, we have branch B1 with three nodes(1[1,2], 3[3,4,5] and 6[6,7,8]. 1, 3 and 6 are nodeIDs (first eventID of the batch). So B1 looks like this: 

     1[1,2]
     /
   3[3,4,5]
  /
6[6,7,8]

Assuming we have branch B2 which contains one ancestor B1 stopping at 6 (exclusive). So B2 inherit nodeID 1 and 3 from B1, and have its own nodeID 6 and 8. Branch B2 looks like this: 

  1[1,2]
  /
3[3,4,5]
 \
  6[6,7]
  \
   8[8]

Now we want to fork a new branch B3 from B2. The only valid forking nodeIDs are 3,6 or 8. 1 is not valid because we can't fork from first node. 2/4/5 is NOT valid either because they are inside a batch.

Case #1: If we fork from nodeID 6, then B3 will have an ancestor B1 which stops at 6(exclusive). As we append a batch of events[6,7,8,9] to B3, it will look like : 

  1[1,2]
  /
3[3,4,5]
 \
6[6,7,8,9]

Case #2: If we fork from node 8, then B3 will have two ancestors: B1 stops at 6(exclusive) and ancestor B2 stops at 8(exclusive) As we append a batch of events[8,9] to B3, it will look like: 

     1[1,2]
     /
   3[3,4,5]
  /
6[6,7]
 \
 8[8,9]

RenameNamespace should be used with caution. Not every namespace can be renamed because namespace name are stored in the database. It may leave database in inconsistent state and must be retried until success. Step 1. Update row in `namespaces_by_id` table with the new name. Step 2. Batch of: 

Insert row into `namespaces` table with new name and new `notification_version`.
Delete row from `namespaces` table with old name.
Update `notification_version` in metadata row.

NOTE: `namespaces_by_id` is currently used only for `DescribeNamespace` API and namespace Id collision check.
