Test Plan

Performance:
Scenario 1: High-Volume Data Loading
LZO is a lightweight compression algorithm optimized for decompression speed (~500MB/s), making it ideal for scenarios requiring rapid data ingestion. Compared to BZip2 (~10MB/s) and GZIP (~100MB/s), LZO provides the fastest decompression while maintaining a reasonable compression ratio.
Why this matters: For time-critical ETL jobs, LZO can reduce load times by 2-5x compared to heavier compression algorithms, while still saving ~50% storage space compared to uncompressed files.
Scenario 2: Hadoop Ecosystem Integration
Many Hadoop ecosystem tools natively support LZO compression:
Scenario 3: Storage Efficiency with Parallel Performance
LZO is splittable, meaning multiple gpfdist instances (or segments) can read different portions of the same file simultaneously. This enables near-linear scalability with additional segments.
