Hyper-scale architecture

10. § Challenge:
• 1 file metadata takes 1KB of on-heap storage
• 1 billion files would take 1 TB of heap space, GC becomes a big problem
§ Solution:
• Add new tier with embedded RocksDB to store inode tree
• Keep an in-memory cache of frequently used inodes
10
Scaling to 1 Billion+ Files
Scale to one billion files and beyond, with performance comparable
to previous on-heap implementation

11. Scaling to 1 Billion+ Files

Structured Data Management

17. § New Alluxio Catalog Service
• Provides the Abstraction of Structured Data
• Attaching a Hive MetaStore like Mounting a File system
• Understand and Serve Schema of Files or Objects
§ New Alluxio Data Transformation Service
• Tranform csv à parquet
• Compact many files à fewer files
