* fix(query): preserve global fetch through physical-optimizer repartitioning Aggregate soft-limit pushdown inserts a global CoalescePartitionsExec(fetch) below an AggregateExec whose input is HashPartitioned/KeyPartitioned. The DataFusion physical optimizer's EnforceDistribution/EnforceSorting passes then dropped or rewrote that fetched coalesce, losing the global limit. Root-caused and fixed in the DataFusion fork (GreptimeTeam/datafusion PR #35); this repo pins to that fix commit and adds regression coverage. - pin datafusion to GreptimeTeam/datafusion 48510c7f5 (fetch preservation fix) - global_limit.rs: adapt to new DF API (input_distribution_requirements, child_distribution, replace_children+Recompute); accept HashPartitioned and KeyPartitioned as partitioning to restore; add regression unit tests - sqlness: extend standalone common ssts and refresh distributed ssts_limit result for the preserved fetch plan Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * refactor: drop dead HashPartitioned compat arms and test wrapper - remove HashPartitioned compatibility matches (pinned DF only emits KeyPartitioned); drop their #[expect(deprecated)] attributes - remove single-use agg_with_limit helper whose seed limit is always overwritten by the soft-limit transform - restore Cargo.lock dependency edges unrelated to the DataFusion pin bump (cargo update --precise had downgraded 26 unrelated packages) Addresses oracle ablation review.

Sqlness Test
Sqlness manual
Case file
Sqlness has two types of file:
.sql: test input, SQL only.result: expected test output, SQL and its results
.result is the output (execution result) file. If you see .result files is changed,
it means this test gets a different result and indicates it fails. You should
check change logs to solve the problem.
You only need to write test SQL in .sql file, and run the test.
Case organization
The root dir of input cases is tests/cases. It contains several subdirectories stand for different test
modes. E.g., standalone/ contains all the tests to run under greptimedb standalone start mode.
Under the first level of subdirectory (e.g. the cases/standalone), you can organize your cases as you like.
Sqlness walks through every file recursively and runs them.
Kafka WAL
Sqlness supports Kafka WAL. You can either provide a Kafka cluster or let sqlness to start one for you.
To run test with kafka, you need to pass the option -w kafka. If no other options are provided, sqlness will use conf/kafka-cluster.yml to start a Kafka cluster. This requires docker and docker-compose commands in your environment.
Otherwise, you can additionally pass the your existing kafka environment to sqlness with -k option. E.g.:
cargo sqlness bare -w kafka -k localhost:9092
In this case, sqlness will not start its own kafka cluster and the one you provided instead.
Run the test
Unlike other tests, this harness is in a binary target form. You can run it with:
cargo sqlness bare
It automatically finishes the following procedures: compile GreptimeDB, start it, grab tests and feed it to
the server, then collect and compare the results. You only need to check if the .result files are changed.
If not, congratulations, the test is passed 🥳!
