* feat: add support for array_contains expression * test: add unit test for array_contains function * Removes unnecessary case expression for handling null values * chore: Move more expressions from core crate to spark-expr crate (apache#1152) * move aggregate expressions to spark-expr crate * move more expressions * move benchmark * normalize_nan * bitwise not * comet scalar funcs * update bench imports * remove dead code (apache#1155) * fix: Spark 4.0-preview1 SPARK-47120 (apache#1156) ## Which issue does this PR close? Part of apache/datafusion-comet#372 and apache/datafusion-comet#551 ## Rationale for this change To be ready for Spark 4.0 ## What changes are included in this PR? This PR fixes the new test SPARK-47120 added in Spark 4.0 ## How are these changes tested? tests enabled * chore: Move string kernels and expressions to spark-expr crate (apache#1164) * Move string kernels and expressions to spark-expr crate * remove unused hash kernel * remove unused dependencies * chore: Move remaining expressions to spark-expr crate + some minor refactoring (apache#1165) * move CheckOverflow to spark-expr crate * move NegativeExpr to spark-expr crate * move UnboundColumn to spark-expr crate * move ExpandExec from execution::datafusion::operators to execution::operators * refactoring to remove datafusion subpackage * update imports in benches * fix * fix * chore: Add ignored tests for reading complex types from Parquet (apache#1167) * Add ignored tests for reading structs from Parquet * add basic map test * add tests for Map and Array * feat: Add Spark-compatible implementation of SchemaAdapterFactory (apache#1169) * Add Spark-compatible SchemaAdapterFactory implementation * remove prototype code * fix * refactor * implement more cast logic * implement more cast logic * add basic test * improve test * cleanup * fmt * add support for casting unsigned int to signed int * clippy * address feedback * fix test * fix: Document enabling comet explain plan usage in Spark (4.0) (apache#1176) * test: enabling Spark tests with offHeap requirement (apache#1177) ## Which issue does this PR close? ## Rationale for this change After apache/datafusion-comet#1062 We have not running Spark tests for native execution ## What changes are included in this PR? Removed the off heap requirement for testing ## How are these changes tested? Bringing back Spark tests for native execution * feat: Improve shuffle metrics (second attempt) (apache#1175) * improve shuffle metrics * docs * more metrics * refactor * address feedback * fix: stddev_pop should not directly return 0.0 when count is 1.0 (apache#1184) * add test * fix * fix * fix * feat: Make native shuffle compression configurable and respect `spark.shuffle.compress` (apache#1185) * Make shuffle compression codec and level configurable * remove lz4 references * docs * update comment * clippy * fix benches * clippy * clippy * disable test for miri * remove lz4 reference from proto * minor: move shuffle classes from common to spark (apache#1193) * minor: refactor decodeBatches to make private in broadcast exchange (apache#1195) * minor: refactor prepare_output so that it does not require an ExecutionContext (apache#1194) * fix: fix missing explanation for then branch in case when (apache#1200) * minor: remove unused source files (apache#1202) * chore: Upgrade to DataFusion 44.0.0-rc2 (apache#1154) * move aggregate expressions to spark-expr crate * move more expressions * move benchmark * normalize_nan * bitwise not * comet scalar funcs * update bench imports * save * save * save * remove unused imports * clippy * implement more hashers * implement Hash and PartialEq * implement Hash and PartialEq * implement Hash and PartialEq * benches * fix ScalarUDFImpl.return_type failure * exclude test from miri * ignore correct test * ignore another test * remove miri checks * use return_type_from_exprs * Revert "use return_type_from_exprs" This reverts commit febc1f1ec1301f9b359fc23ad6a117224fce35b7. * use DF main branch * hacky workaround for regression in ScalarUDFImpl.return_type * fix repo url * pin to revision * bump to latest rev * bump to latest DF rev * bump DF to rev 9f530dd * add Cargo.lock * bump DF version * no default features * Revert "remove miri checks" This reverts commit 4638fe3aa5501966cd5d8b53acf26c698b10b3c9. * Update pin to DataFusion e99e02b * update pin * Update Cargo.toml Bump to 44.0.0-rc2 * update cargo lock * revert miri change --------- Co-authored-by: Andrew Lamb <andrew@nerdnetworks.org> * update UT Signed-off-by: Dharan Aditya <dharan.aditya@gmail.com> * fix typo in UT Signed-off-by: Dharan Aditya <dharan.aditya@gmail.com> --------- Signed-off-by: Dharan Aditya <dharan.aditya@gmail.com> Co-authored-by: Andy Grove <agrove@apache.org> Co-authored-by: KAZUYUKI TANIMURA <ktanimura@apple.com> Co-authored-by: Parth Chandra <parthc@apache.org> Co-authored-by: Liang-Chi Hsieh <viirya@gmail.com> Co-authored-by: Raz Luvaton <16746759+rluvaton@users.noreply.github.com> Co-authored-by: Andrew Lamb <andrew@nerdnetworks.org>

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
This is a follow on suggestion from @rdettai on #1153 https://github.com/apache/arrow-datafusion/pull/1153/files#r735437280
Namely the substitution of
now()for the current value is better described as "constant evaluation" rather than "algebraic simplification" so it should be done in theConstEvaluatorcode.Describe the solution you'd like
Move code to fold
now()fromSimplifier()toConstEvaluatorThe text was updated successfully, but these errors were encountered:
