[GitHub] [pulsar] sijie opened a new issue #4775: [SQL] Optimize handling date related types in presto handler

sijie opened a new issue #4775: [SQL] Optimize handling date related types in presto handler
URL: https://github.com/apache/pulsar/issues/4775
 
 
   **Is your feature request related to a problem? Please describe.**
   
   Currently Presto is using `Schema` implementation to serialize and deserialize types. Schema stores `Date`, `Timestamp` and `Time` as epoch timestamp in the same way. So presto has to deserialize the serialized message back to java util `Date`, `Timestamp` and `Time`. There can be performance penalty due to object allocations. If it happens to be a bottleneck, we need to seek a solution to optimize it.
