I recently posted an article on Dimensional Benchmarking of Oracle v10-v12 Queries for SQL Bursting Problems. This article added an Oracle v12 SQL solution, involving Match_Recognize to benchmark against some v10 and v11 solutions that I had posted on Scribd a few years ago. A few days before posting it I noticed an OTN thread with a problem that struck me as being of a similar type, Amalgamating groups to be beyond a given size threshold. Where in my original ‘bursting’ problem a group is defined by a maximum interval from its starting date, in the OTN problem a group is defined by the cumulative sum of a numeric attribute from the group starting record.
I added a comment on the thread at the time mentioning the results that I had got on the original problem, and adding a model solution for the problem raised on the new thread. I have now taken this second ‘bursting’-type problem and have benchmarked both the main two solutions proposed on that thread (by other posters), as well as two versions of my own model solution, and a variant of the recursive subquery factor solution that uses a temporary table to achieve much faster performance.
Also, I noticed a question just yesterday on AskTom that is posing essentially the same problem as in my earlier article (which itself came from AskTom several years ago 🙂 ), Complex sql.
The results show that Match_Recognize, as before, is by far the most efficient solution. They also show that the faster solutions vary linearly with dataset size (within a given partition), while the slow ones vary quadratically. One interesting finding is that the solution by the Model clause can be changed from very slow, and quadratically varying, to linearly varying, and second in performance only to Match_Recognize, by using a rule ordering clause (which avoids the need for automatic rules ordering).
I obtained these results on my Windows 10 home computer with Oracle 12.1, and used my own benchmarking framework, available on GitHub, A Framework for Dimensional Benchmarking of SQL Query Performance.
Generalised ‘Bursting’ Problem Definition
The problem is to determine break groups using a running aggregate based on some function of the record attributes, with a defined ordering, starting from the group starting record, and with a group’s end record defined by the aggregate reaching (or exceeding) some limit. One may consider the first record reaching (or exceeding) the limit to define the first record in the next group, as in the original bursting problem, or to be the last record in the current group, as in the OTN example.
The data are partitioned by some key in general.
OTN-like Item Weights ‘Bursting’ Problem
The data structure used in this article is based on that of the original poster in the OTN thread, but with more generic table and column names.
ITEMS Table
CREATE TABLE items (
id NUMBER NOT NULL,
cat VARCHAR2(30) NOT NULL,
seq NUMBER NOT NULL,
weight NUMBER NOT NULL,
CONSTRAINT itm_pk PRIMARY KEY (id)
)
/
CREATE INDEX items_N1 ON items (cat, seq)
/
DROP SEQUENCE itm_s
/
CREATE SEQUENCE itm_s
/
Functional Test Data
I created test data with a test weight limit of 10, as follows, with groups shown at detailed level. The first two categories are taken from the OTN problem, while I added a third category to test the case where the limit is not reached.
ID CAT SEQ WEIGHT SUB_WEIGHT FINAL_GRP --- ------------------------------ ---------- ---------- ---------- ---------- 1 Rural 10 2 2 4 2 9 3 5 4 3 8 1 6 4 4 7 4 10 4 5 6 11 11 5 6 5 2 2 9 7 4 2 4 9 8 3 4 8 9 9 2 30 38 9 10 1 12 12 10 11 Urban 10 1 1 12 12 9 12 13 12 13 8 2 2 15 14 7 5 7 15 15 6 7 14 15 16 5 15 15 16 17 4 25 25 17 18 3 2 2 20 19 2 1 3 20 20 1 8 11 20 21 Suburban 10 2 2 22 22 9 1 3 22 22 rows selected.
The queries shown later give the groups at summary level, as follows:
CAT # Groups ------------------------------ ---------- Rural 4 Suburban 1 Urban 5
A Note on Functional Testing and ‘Scenario Coverage’
In the Match_Recognize query proposed in the OTN thread the pattern is defined in terms of two categories, say s and t, where:
- s denotes a record where the running sum < the limit
- t denotes a record where the running sum >= the limit
The pattern to match can be written as (s* t?) meaning zero or more category s records, followed by zero or one category t records. This immediately suggests that any given match falls into one of the following scenarios for frequencies of (s, t):
- (0, 0) – this looks like an empty set of records, but could be non-empty if null values were allowed for the weight
- (1+, 0) – the case where the limit is not reached, which must be the last match if there are no null weights
- (0, 1) – where the first record in a group reaches the limit by itself
- (1+, 1) – where one or more records in a group are below the limit, followed by a record that reaches the limit
In the results above, we see that group 22 matches scenario 2, while groups 10, 16 and 17 match scenario 3, and the remainder match scenario 4. We take the weight to be not null so scenario 1 is not possible. This kind of ‘scenario coverage’ is much more important than the ‘code coverage’ that is often focussed on in testing, especially by object oriented programmers.
In the following sections for individual queries, the query (and other SQL) is listed first, followed by the execution plan for the largest problem (W40-D8000).

Notes on Model Query 1 – Automatic Order (MOD_QRY)
The default rules order for Model is sequential, but if we specify sequential, or accept the default, in the query above, then we get the error:
ORA-32637: Self cyclic rule in sequential order Model
Rule Dependency in AUTOMATIC ORDER Models
In some cases, Oracle Database may not be able to ascertain that your model is acyclic even though there is no cyclical dependency among the rules. This can happen if you have complex expressions in your cell references. Oracle Database assumes that the rules are cyclic and employs a CYCLIC algorithm that evaluates the model iteratively based on the rules and data. Iteration stops as soon as convergence is reached and the results are returned. Convergence is defined as the state in which further executions of the model will not change values of any of the cell in the model. Convergence is certain to be reached when there are no cyclical dependencies.
When we specify automatic order, the solution is obtained without error using Oracle’s cyclic algorithm (operation SQL MODEL CYCLIC). Unfortunately, in this case there is a large performance impact, and we will see in the results section that execution time varies as the square of the number of records within a partition, i.e. quadratically.

Notes on Model Query 2 – Sequential Order (MOD_QRY_D)
In the query above, the rules order clause is omitted, thus defaulting to sequential, while avoiding the ORA-32637 error. This is achieved by specifying ORDER BY rn DESC on the left side of the second rule. The solution, via operation SQL MODEL ORDERED is much faster, and we will see in the results section that execution time now varies linearly with the number of records within a partition.

Notes on Match Recognize Query (MTH_QRY)
The query above is essentially the same as one of the posters proposed on the OTN thread, with a slight tweak to the pattern that does not alter its meaning, and also changing it to return one row per match. The query performs much more efficiently than any of the other queries, using the Match_Recognize clause introduced in Oracle 12.1 SQL for Pattern Matching.

Notes on Recursive Subquery Factors Query 1 - Direct (RSF_QRY)
This is based on the second of the recursive subquery factor queries in the OTN thread, and we can see the performance issue in the plan above. The recursive branch of the UNION ALL executes once for each record within a partition and performs a full scan on the items table each time. This results in execution time varying as the square of the number of records within a partition, as can be seen in the results section later. The performance can be much improved by using a temporary table, as in the next query.

Notes on Recursive Subquery Factors Query 2 - With Temporary Table (RSF_TMP)
In this solution, the initial subquery from the previous query is written to a temporary table that is indexed on the join column. This means that the join in the recursive branch of the UNION ALL is indexed and much quicker, resulting in linear variation in execution time with the number of records in a partition.
Notice that it was necessary to hint the index usage. It is possible to achieve the indexed join without a hint by including a call to gather statistics in the pre-query SQL. Unfortunately, Oracle's DBMS_Stats procedure performs a commit - which clears the data from the temporary table. Although we could get around the clearing of the table by making it a normal table and manually truncating it, it is probably better to accept this as a valid use-case for a hint - after all, the whole purpose of the temporary table is to permit index use.
Performance Testing Results
The 'width' parameter is taken to be the number of cat values partitioning the dataset, while the 'depth' parameter is taken to be the number of records within each category. The weight is assigned a random integer between 1 and 100, and the weight limit is 5,000.

Performance Discussion
Variation with Width
The width parameter represents the number of categories here, and category (CAT) is the query partitioning key. We might therefore expect that the execution time would be proportional to the width when the depth parameter is fixed. The width values used were 10, 20 and 40, so we would expect times to double between W10 and W20, and again between W20 and W40.
In fact, we see from the width ratios columns in the tables that this expectation is very closely matched in the cases of MOD_QRY_D, RSF_QRY, AND RSF_TMP.
For MOD_QRY, the ratios are quite variable, and mostly above 2, so that the CYCLIC Model algorithm does not meet our expectation.
For MTH_QRY (Match_Recogize), the elapsed times are very small, 0.17 for the largest problem (14 times faster than the next best, MOD_QRY_D), and that likely explains the variance.
Variation with Depth
The depth parameter represents the number of of records for each category. The depth ratios show that two of the queries show very close to quadratic variation of time with depth, while three show very close to linear variation, and the linear queries are unsurprisingly much faster.
MOD_QRY and RSF_QRY vary quadratically with depth (number of records per partition key).
MOD_QRY_D, MTH_QRY, AND RSF_TMP vary linearly with depth (number of records per partition key).
Conclusions
- As in the earlier article, the new v12.1 feature Match_Recogize proved to be much faster than the other techniques for this problem
- The solution using Model clause with the operation SQL MODEL CYCLIC showed quadratic variation in execution times with size, but a very simple change to allow SQL MODEL ORDERED operation produced linear variation, and was second only to Match_Recogize in performance
- Recursive subquery factoring had timings that increased quadratically with number of records; this was due to a combination of the number of starts of a subquery, and full scans within it
- This kind of unscaleable quadratic resource usage can often be avoided by the use of a temporary table with appropriate indexes, as demonstrated here. There is another example of its use for performance improvement here, SQL for Shortest Path Problems 2: A Branch and Bound Approach
- It's hard to see how you could detect some of the performance characteristics found here without benchmarking across varying problem sizes
