What do epoch, sequence number, offset, owner, token mean in azure event hubs?

What do the epoch, sequence number, token, which is stored through the consumer group, mean?

The following forms are stored in azure Blob storage : 

{  
   "Offset":"8251440",
   "SequenceNumber":10576,
   "PartitionId":"11",
   "Owner":"host-93e93907-df5f-4643-a784-5931e8fb787f",
   "Token":"24f1c215-688f-462f-b78f-142943ab123a",
   "Epoch":2437
}

I want to know what these mean

Lease.Offset Property

Gets or sets the current value for the offset in the stream.

Lease.Owner Property

Gets or sets the host owner for the partition.

Lease.PartitionId Property
