flumelog-offset is a log storage system where each record's position in the file serves as its key, enabling O(1) read access. Built on aligned-block-file for efficient caching, it stores data in an append-only format with double-ended framing for bidirectional scanning. This project is designed for developers working with event logging or data streaming applications, particularly those using the FlumeDB ecosystem. It's ideal for systems requiring fast, sequential access to immutable data like audit trails, time-series data, or append-only databases.
