Method for simultaneously reading and writing RocksDB by multiple processes based on RPC proxy

Abstract

The invention discloses a method for simultaneously reading and writing RocksDB by multiple processes based on RPC agency, at a RocksDB server side, an RPC agency server side module needs to be started firstly, the subsequent reading and writing operations of the processes are not different from the original use mode of the RocksDB, and at a RocksDB client side, whether the RocksDB server side is the same server or other node servers, the RocksDB server side module needs to be started firstly, and the RocksDB client side module needs to be started firstly. According to the method for simultaneously reading and writing the RocksDB by the multiple processes based on the RPC proxy, the RPC proxy client module needs to be started firstly, the RPC proxy client service module is automatically connected to the RPC proxy server module through the RPC, and the operation processes such as reading and writing of the processes after the processes are prepared are not different from the original use mode of the RocksDB. The problem that multiple processes cannot access the RocksDB at the same time can be solved based on the RPC proxy.

Description

Technical field [0001] The present invention relates to the technical fields of RPC and RocksDB products, specifically a method for solving the problem of simultaneous reading and writing of RocksDB by multiple processes based on RPC agents. Background technique [0002] RocksDB is a C++ library that can handle persistent storage of billion-level Key-Value data. RocksDB is developed and open sourced by Facebook, and is a secondary development based on Google's open source LevelDB. Well-known projects such as TiKV, MyRocks, CrockRoach, etc. As RocksDB is widely used, an obvious flaw limits its continued development. Although RocksDB allows access by multiple processes, only one process is writable, and other processes are read-only. In reality, there is an obvious usage scenario: one process reads and writes RocksDB, and other local processes and even remote processes also read and write the same RocksDB at the same time. RocksDB does not provide an ideal solution for this s...

AI Technical Summary

Problems solved by technology

As RocksDB is widely used, an obvious defect limits its further development. Although RocksDB allows multi-process access, only one process is writable, and other processes are read-only.

In reality, there is an obvious usage scenario: one process reads and writes RocksDB, and other local processes and even remote processes also read and write the same RocksDB at the same time. RocksDB does not provide an ideal solution for this scenario.
