---------------------------------

             Summary: Using compression code of Intel® ISA-L to improve ZLIB performance
                 Key: ORC-175
                 URL: https://issues.apache.org/jira/browse/ORC-175
             Project: ORC
          Issue Type: Improvement
          Components: Java
            Reporter: iamhumanbeing


The Intel® Intelligent Storage Acceleration Library (Intel® ISA-L) is a collection of optimized
low-level functions used primarily in storage applications, but given the flexibility inherent
to low-level implementations, ISA-L has ramifications for software well beyond the storage
domain. The open source versions contain multiple units that include functions to implement
fast erasure codes, data protection & integrity, compression, hashing and encryption.

We used ZLIB code of ISA-L to get 200% compression improvement and 50% decompression improvement
for ORC FILE.
