This is an expensive operation ( ~30 msec to build) and allocates ~2M on heap for each query. For high throughput, low latency operational queries, we quickly run out of heap memory, causing JVM hangs. Build operator table once during startup for static built-in functions and save in DrillbitContext, so we can reuse it across queries. > Provide a system/session option to not use dynamic UDFs so we can use the operator table saved in DrillbitContext and avoid building each time. > *Please note, changes are adding new option exec.udf.use_dynamic which needs to be documented.* -- This message was sent by Atlassian JIRA (v6.3.15#6346)
