Description

when query lineage info for hive, the throughput reachs only 3 query per second.

we use jstack and jfr+flame graph tools and found that the GremlinGroovyScriptEngine object loading class logic takes much of the time. so we make the GremlinGroovyScriptEngine a global singleton object, which would be shared accross all query threads. finally the query performance improved much and got 200 qps.
