Replicant is a MultiPaxos-based linearizable distributed key-value store that uses MultiPaxos for state machine replication (SMR) implementation. Replicant includes the following modules:
- MultiPaxos module: MultiPaxos implementation. It communicates with other MultiPaxos modules running on other Replicants to reach a consensus on decided values in the log.
- Log module: MultiPaxos Protocol Log. It is a thread-safe unbounded producer-consumer queue.
- KVStore module: key-value store wrapper. Currently, it supports two types of stores, in-memory hash table and RocksDB.
Replicant handles commands from clients and pass commands to the MultiPaxos
module You can find specific interface designs and pseudocode in doc.
We have six versions using different languages (C++, Java, Go, and Rust) and network communication protocols (gRPC or TCP). All of them are independent and follow the same architecture and interface design mentioned above.
You can find how to run C++ version in the README.MD under the c++ folder.
