 Project: Apache Arrow
  Issue Type: New Feature
  Components: C++ - Gandiva
Reporter: Siddhant Rao


The current conversion of sql like patterns to pcre doesn't work if the escape 
character is one of the special characters to pcre. Fix this by not escaping 
those characters if it the escape character itself.

 Arrow gandiva has a primary cache but this cache doesn't persist across restarts. Integrate a new API in project and filter make calls that allow the user to specify the implementation of the secondary cache by providing a c++ and java interface to this persistent cache.

The size 0 case in arena malloc is causing sporadic errors due to null pointer 
being returned to functions like convert_from which treat this as an error.
