Homework projects of PNA

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.

Project 1:

PNA doc|tag

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

Project 2:

PNA doc|tag

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

Project 3:

PNA doc|tag

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 std networking APIs
• Introduce logging to the server
• Implement pluggable backends with traits
• Benchmark the hand-written backend against sled

Project 4:

PNA doc|tag

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
