---------------------------------
Summary: pool performance in hive lineage query
Key: ATLAS-3519
URL: https://issues.apache.org/jira/browse/ATLAS-3519
Project: Atlas
Issue Type: Improvement
Components: atlas-core
Affects Versions: 2.0.0, 1.1.0
Reporter: zhangxiong
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.
