Qifan Chen has uploaded a new patch set (#54). (

Change subject: IMPALA-10325: Parquet scan should use min/max statistics to
skip pages based on equi-join predicate
......................................................................
IMPALA-10325: Parquet scan should use min/max statistics to skip pages based on
equi-join predicate
This patch adds a new class of predicates called overlap predicates
to aid in the determination of whether a Parquet row group or a page
overlap with a range computed from an equi hash join. If not, then
the entire row group or page are skipped. When a row survives this way,
it can be subjected to the row-level overlapping test against the same
overlap predicate.
For the following query, the min and max in the overlap predicate are
computed with the values from the join column from table 'b'. To
evaluate the overlap predicate, these two values are compared against
the min/max of each row group or page at the scan node for 'a'.
select straight_join count(*)
from lineitem a join [SHUFFLE] lineitem b
where a.l_shipdate = b.l_receiptdate
and b.l_commitdate = "1992-01-31";
An overlap predicate associated with the column type J (in hash table)
and scan column type S will be formed when one of the following is true:
Both J and S are booleans
Both J and S are integers (tinyint, smallint, int, or bigint)
Both J and S are approximate numeric (float or double)
Both J and S are decimals with the same precision and scale
Both J and S are strings (STRING, CHAR or VARCHAR)
Both J and S are date
Both J and S are timestamp
The overlap predicate is implemented as a min/max filter. Unlike
existing min/max filters, MAX_NUM_RUNTIME_FILTERS query option does
not apply to min/max filters created for overlap predicates. An overlap
predicate will be evaluated as long as the overlap ratio is less than a
thresold specified in a new query option 'minmax_filter_threshold'.
Setting the threshold to its minimal value 0.0 disables the feature,
and setting it to the maximal value 1.0 applies the filtering in all
cases.
In addition, two new run-time profile counters are added to report the
number of row groups or pages filtered out via the overlap predicates
respectively:
1. NumRuntimeFilteredRowGroups
2. NumRuntimeFilteredPages
Testing:
1. Unit tested on various column types with TPCH and TPCDS tables.
Benefits were significant when the join column on the outer table
is sorted and there exist many row groups or pages no overlapping
with the implementing min/max filters;
2. Added following new tests:
a. in min_max_filters.test to demonstrate the number of filtered
out pages and row groups with the two new profile counters;
b. in runtime-filter-propagation.test to demonstrate that the
overlap predicates work with different column types;
c. data type specific overlap method tests in
min-max-filter-test.cc;
3. Core testing;
4. Performance measurement.
To do in follow-up JIRAs:
1. Improve filtering efficiency;
2. Apply the overlap predicate on partition columns;
3. IR code-gen for various MinMaxFilter::EvalOverlap methods.
