- Download protobuf https://github.com/protocolbuffers/protobuf/releases/tag/v3.18.1 and put it into ./protobuf-3.18.1
- Run
make all
- Each client uses a single tcp socket for communication with the server
- All messages have the following form: message_type (1 byte) message_len (4 bytes) message_data (message_len bytes)
- message_data is the serialized form for one of the messages described in
kv.proto - Each request and each response message contains a request_id field used to match responses vs requests
- Start the server @ port 4242:
./server 4242 - Run put + get stages with 100 requests via the client:
./client 4242 100 put get - Run only the get stage via the client:
./client 4242 100 get - Run put + get stages with debug-level logging via the client:
VERBOSITY=4 ./client 4242 100 put get
See the code for more details
- Implement a simple_client that would be used to send single requests, specified via cmdline parameters
- The hash table used in the server should be persistent (right now it's just an ordinary std::unordered_map)
- After making this hash table persistent, implement a persistent key-value storage based on this hash index
