-------------------------------------
Summary: Add option to use JDK compiler and use it for runtime
generated code over a certain threshold
Key: DRILL-1155
URL: https://issues.apache.org/jira/browse/DRILL-1155
Project: Apache Drill
Issue Type: Sub-task
Components: Execution - Codegen
Affects Versions: 1.0.0-BETA1
Reporter: Aditya Kishore
Assignee: Aditya Kishore
This is related to DRILL-1095 however it would not completely resolve the issue
since the Java class file format enforces a maximum limit of 64K on a code unit.
However, it does provide some additional headroom as JDK compiler seems to
generate slightly smaller bytecode compared to Janino and seems to be faster
for source code sizes over a threshold (approximately 256K in my tests). For
smaller source code Janino is order of magnitude faster than JDK compiler.
