Explore different branches to track the code's evolution, with the main branch containing the final code. Key implemented features include:
- Custom Protocol (TLV - Type-Length-Value)
- Event Loop and Non-Blocking IO - using
poll() - Efficient Hashtables with Chaining and Progressive Resizing
- Data Serialization
- AVL Trees - implement
zset - Timers for poll() using a doubly-linked list
- Min-Heap for Time-To-Live (TTL) tracking
- Multi-threading for handling resource-intensive operations like zset deletions
General Key-Value Commands
keys- Lists all keys along with their corresponding values.get- Retrieves the value associated with a given key.set- Sets a key to hold a specified string value.del- Deletes a specified key and its associated value.pexpire- Sets a time-to-live (TTL) for a key in milliseconds.pttl- Returns the remaining time to live of a key with a TTL, in milliseconds.
ZSet (Sorted Set) Commands
For more info, check server/zset/README.md
zadd- Adds one or more members to a sorted set with associated scores.zrem- Removes one or more members from a sorted set.zscore- Returns the score of a member in a sorted set.zquery- Performs queries and operations on sorted sets.
Before running the project, ensure you have the following tools installed:
sudo apt install make g++cd server
make# new terminal
cd client
makeAfter the compilation step, you can run the server and client as needed.
To remove the executables, type
make clean
