Snappy

In Hadoop/Impala environments,

Snappy was the default choice due to its "low CPU usage and fast speed" requirements. However, as storage space grew to tens of TB~PB, "compression ratio" became crucial. Now,

zstd is becoming the new standard as it creates 20-50% smaller files at similar speeds.
