{"success":true,"data":{"ext":"rc","name":"RC","description":"RC is a columnar storage file format originally developed at Facebook and later maintained within the Apache Hadoop ecosystem. It is used for storing large analytical datasets and for efficient processing in distributed data systems, especially where column-oriented access patterns improve compression and query performance. The format is generally safe, though as a legacy big-data container it is best handled with current software to ensure compatibility.","mime":[],"risk_level":"Safe","signatures":[{"hex":"53 45 51 36","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":[],"usage":{"python":"def is_rc(file_path: str) -> bool:\n    \"\"\"Check if file is a valid RC by magic bytes.\"\"\"\n    signature = bytes([0x53, 0x45, 0x51, 0x36])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isRC(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x53, 0x45, 0x51, 0x36]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsRC(data []byte) bool {\n    signature := []byte{0x53, 0x45, 0x51, 0x36}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
