Webb1 nov. 2016 · The MongoDB sharding solution is similar to existing sharding frameworks for other major database solutions. It makes use of a typical lookup solution, where the sharding is defined in a shard-key and the ranges are stored inside a configuration database. MongoDB works with three components to find the correct shard for your data. WebbBut if, for example, A-B and V-X become canonical, then one part of the transaction is finalized and one is abandoned, creating an atomicity failure. We will cover how this problem is addressed in proposed protocols in the second part, when covering changes to the fork-choice rules and consensus algorithms proposed for sharded protocols.
