xRedis

Author: xSky

Redis C++ client, support the data slice storage, support the connection pool

Features:

Support multi-node distributed storage of data, can customize the sharding rules;
Support to connect to master and slave nodes of each shard at the same time, support separation of master and slave reads and writes;
Support connection pooling for each storage node;
Support simultaneous connection of multiple data sharding clusters;
Support for connecting to official clusters, single or multiple nodes Support to set up a connection pool to each node,
the client side automatically calculates the slot distribution;
Support automatic calculation of node index position;
Support Redis cluster node change connection automatic switch;
The connection pool to the cluster is automatically updated when the add/delete /slot distribution of the official cluster node changes.
Provide easy to use C++ interface encapsulation, has implemented most of the Redis command;
Only rely on the Hiredis library; Multi-thread safety Support password connection; Support Linux and Windows platforms
