Welcome to the VShard wiki

VShard is a sharding module for Tarantool based on Virtual Buckets concept. Data is first assigned to virtual buckets, which are subsequently mapped to physical shards. Every shard consists of one or several storages, they store a sharded data. Routers are intended for routing user requests to the needed shard based on bucket ID.

This wiki contains some low-level technical details on VShard and is intended for developers mostly. It also contains useful scripts for debugging and restoring of the cluster during incidents.
