Nodex

NodeX is a Geth read-only cluster synchronization solution based on a master-slave architecture, which does not require peer-to-peer or consensus components. Based on Kafka and S3, NodeX's reader geth nodes can synchronize without the need for p2p communication and block validation.

Components

• Write nodes: a normal geth node, which is used to synchronize the block data to S3 and Kafka. Each time Blockheader is committed, they are first committed to S3.
• Compute nodes: Compute nodes, follow write nodes without block synchronization.No local disk is mounted, the database is accessed via the Remotedb interface through gRPC.
• Remotedb: Read from S3, apply Blockdata and Blockheader to the DB, and provide an access interface to the underlying data for Compute nodes via gRPC.
• S3Proxy: A proxy that provides access to S3 data for Write nodes and Remotedb via gRPC.
• Ndrc: A command line tool for managing NodeX clusters.
