URL: https://github.com/apache/arrow-datafusion/pull/2895
# Which issue does this PR close?
Closes #2894
# Rationale for this change
Add session option 'datafusion.explain.logical_plan'.
when set to true, the explain statement will only print logical plans. We
can set environment variable DATAFUSION_EXPLAIN_LOGICAL_PLAN to make this value
take effect.
For example:
explain select count(*) from (values ('a', 1, 100), ('a', 2, 150)) as t
(c1,c2,c3);
+--------------+----------------------------------------------------------------------------------+
| plan_type | plan
|
+--------------+----------------------------------------------------------------------------------+
| logical_plan | Projection: #COUNT(UInt8(1))
|
| | Aggregate: groupBy=[[]], aggr=[[COUNT(UInt8(1))]]
|
| | Values: (Utf8("a"), Int64(1), Int64(100)), (Utf8("a"),
Int64(2), Int64(150)) |
+--------------+----------------------------------------------------------------------------------+
