# Which issue does this PR close? Closes #4140. # Rationale for this change Currently datafusion will parse some joins as `cross join` when left or right join key contain normal expression. For example, `select * from test0 INNER JOIN test1 ON test0.c0 + 1 = test1.c1 * 2`. To improve performance, these joins should also parse as `join`. # What changes are included in this PR? * Support extract expression join key in `extract_join_keys`. * Add projection if needs when create logical plan of join. # Are these changes tested? Yes # Are there any user-facing changes? -- This is an automated message from the Apache Git Service.
