There are 2 potential reasons to cancel pipelineX query timeout.
Cancel fragment context first and set ready to execute will set cancel flag to false.
Dead lock.
when aggregate function roll up, we should check the qury and mv function argument is equal
such as mv def and query sql as following, it should not rewrite success, because the bitmap_union_basic field augument is
not equal to the `count(distinct case when o_shippriority > 10 and o_orderkey IN (1, 3) then o_custkey else null end)` field in query
mv def:
> select l_shipdate, o_orderdate, l_partkey, l_suppkey,
> sum(o_totalprice) as sum_total,
> max(o_totalprice) as max_total,
> min(o_totalprice) as min_total,
> count(*) as count_all,
> bitmap_union(to_bitmap(case when o_shippriority > 1 and o_orderkey IN (1, 3) then o_custkey else null end)) as bitmap_union_basic
> from lineitem
> left join orders on lineitem.l_orderkey = orders.o_orderkey and l_shipdate = o_orderdate
> group by
> l_shipdate,
> o_orderdate,
> l_partkey,
> l_suppkey;
query sql:
> select t1.l_partkey, t1.l_suppkey, o_orderdate,
> sum(o_totalprice),
> max(o_totalprice),
> min(o_totalprice),
> count(*),
> count(distinct case when o_shippriority > 10 and o_orderkey IN (1, 3) then o_custkey else null end)
> from (select * from lineitem where l_shipdate = '2023-12-11') t1
> left join orders on t1.l_orderkey = orders.o_orderkey and t1.l_shipdate = o_orderdate
> group by
> o_orderdate,
> l_partkey,
> l_suppkey;
My organization uses HMS catalog to accelerate Lake query. Sine we have custom distributed file system and hard to integrate to FE / BE, we introduce HMS Catalog broker scan support (#24830) and implement custom distributed file system adaption in broker.
We want to expand the scope of use to Iceberg table scan in HMS Catalog. This PR introduces broker-scan-related `IcebergBrokerIO`, `BrokerInputFile`, `BrokerInputStream` for Iceberg table scan

Do not index any string longer than this value. Defaults to 2147483647 so that all values would be accepted. Please however note that default dynamic mapping rules create a sub keyword field that overrides this default by setting ignore_above: 256.
When the field value is longer than the limitation, we will get an empty result.
The solution is turn off `enable_docvalue_scan`, to get data from `_source` field.
