Thanks Jozef , Vaclav and Robert for the detailed explanation.

But I would like to know the problem that it is solving. Since when a node (who is the master of the switch) goes down , the transactions that are initiated towards it also dies and the new master can re-trigger the same transaction and the datastore writes are taken care by the inventory-shard-leader


This is solving the multiple-writer problem: you have to ensure former leader is quiescent before the new leader starts touching the datastore -- otherwise the two will collide.

Bye,
Robert
