Webb9 apr. 2024 · By breaking the blockchain into multiple parts and processing them in parallel, sharding should radically improve how much computation the network can handle at once. Even a handful of shards would dramatically improve Ethereum’s scaling potential, but with nearly 7,000 nodes at its disposal, the outcome could be much more remarkable. WebbA shard is a replica set that contains a subset of the cluster’s data. The mongos acts as a query router for client applications, handling both read and write operations. It dispatches client requests to the relevant shards and aggregates the result from shards into a consistent client response. portisheadgibbon
