Tian Jiang created IOTDB-557:
--------------------------------
Summary: Use generalized "and" and "or"
Key: IOTDB-557
URL: https://issues.apache.org/jira/browse/IOTDB-557
Project: Apache IoTDB
Issue Type: Improvement
Components: Planner/SQLOptimizer
Reporter: Tian Jiang
We only use binary "and" and "or" in expression construction, as a result, a
filter like "root.group1.*.s1 > 1" (* ranges from d1 to d100) will result in a
filter tree of over 100 nodes, which could be a great waste when there are even
more series.
By using generalized "and" and "or", we can replace such a filter tree with
just one filter node, which I think could relieve the Java GC a lot.
