             Summary: Support multiple caching algorithms for codegen cache
                 Key: IMPALA-11820
                 URL: https://issues.apache.org/jira/browse/IMPALA-11820
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Yida Wu


Currently we use LRU for the codegen cache, it is good to also investigate other algorithms, like LIRS or TinyLFU, which may bring benefits for the cache size or hit rate.
