A fast and efficient log parser written in Go that scans multiple log files simultaneously, extracts lines that start with ERROR, and writes them to a specified output file. Designed with performance and concurrency in mind.
- 🗂️ Parses multiple log files at once.
- 🚨 Filters lines that start with
ERROR. - 📄 Writes the results to a specified output file.
- 🧵 Uses concurrent goroutines for parallel processing.
- 🧠 Employs RWMutex to ensure thread-safe access to shared channels.
- 🧠 Reads and writes using buffers with a max size of 1MB to keep memory usage under control – even for large log files.
