v0.1.1

FireflyDB

FireflyDB is a fast, thread-safe, JVM-based key-value storage engine with microsecond latency. FireflyDB is 20x faster
for reads and 10x faster for writes than Bitcask, which has a similar architecture.

Installation

Maven

<dependency>
    <groupId>com.sahilbondre</groupId>

API

FireflyDB fireflyDB=FireflyDB.getInstance("path/to/db");
    fireflyDB.start();

// Write
    byte[]key="testKey".getBytes();
    byte[]value="testValue".getBytes();

    fireflyDB.put(key,value);

// Read
    byte[]result=fireflyDB.get(key);

// Compaction 
// FireflyDB will compact automatically but can be triggered on demand.
    fireflyDB.compact();

    fireflyDB.stop();

Potential Improvements

• Add an explicit delete operation.
• Expose compaction size as a configuration option.
• Expose compaction interval as a configuration option.
• Allow larger key size as a configuration option.
• Expose read only mode.
