METHOD AND SYSTEM OF IMPLEMENTING A DISTRIBUTED DATABASE WITH PERIPHERAL COMPONENT INTERCONNECT EXPRESS SWITCH

摘要

In one exemplary aspect, a method a Peripheral Component Interconnect Express (PCIe) based switch that provides a bridge between a set of database nodes of the distributed database system is provided. A failure in a database node is detected. A consensus algorithm is implemented to determine a replacement database node. A database index of a data storage device formally managed by the database node that failed is migrated to a replacement database node. The PCIe-based switch is remapped to attach the replacement database node with the database index to the data storage device.

1. A method of a distributed database system comprising:
providing a Peripheral Component Interconnect Express (PCIe) based switch that provides a bridge between a set of database nodes of the distributed database system; detecting a failure in a database node; implementing a consensus algorithm to determine a replacement database node; and migrating, with the PCIe based switch, an index of a data storage device formally managed by the database node that failed to a replacement database node.
