This repository contains my homework projects of Practical Networked Applications(PNA) in Rust which is a part of PingCAP Talent Plan. The structures and test cases are adapted from PNA.
Task: Create an in-memory key/value store that passes simple tests and responds to command-line arguments.
Goals:
- Install the Rust compiler and tools
- Learn the project structure used throughout this course
- Use
cargo init/run/test/clippy/fmt - Learn how to find and import crates from [crates.io][crates.io]
- Define an appropriate data type for a key-value store
- Limit the size of key up to 256B, the size of Value up to 4KB
Task: Create a persistent key/value store that can be accessed from the command line.
Goals:
- Handle and report errors robustly
- Use serde for serialization
- Write data to disk as a log using standard file APIs
- Read the state of the key/value store from disk
- Map in-memory key-indexes to on-disk values
- Periodically compact the log to remove stale data
Task: Create a single-threaded, persistent key/value store server and client with synchronous networking over a custom protocol.
Goals:
- Create a client-server application
- Write a custom protocol with
stdnetworking APIs - Introduce logging to the server
- Implement pluggable backends with traits
- Benchmark the hand-written backend against
sled
Task: Create a multithreaded, persistent key/value store server and client with synchronous networking over a custom protocol.
Goals:
- Write a simple thread pool
- Use channels for cross-thread communication
- Share data structures with locks
- Perform read operations without locks
- Benchmark single-threaded vs multithreaded
