  • Storage Efficiency

Answer

Adaptive compression
  • Adaptive compression combines fewer blocks of data into a compression group (8K).
  • The compression group is then compressed and stored as a single block.
  • When a user requests data from this compression group, less time is taken to decompress and provide that data to the user, thereby improving the read performance.
  • In general, adaptive compression is better suited for random workloads.
  • Adaptive compression provides relatively fewer savings as compared to secondary compression, but with better performance.
