BigQuery problem resources exceeded during query execution

Question

I am using BigQuery and get the following error when trying to execute a somehow complex query:

Resources exceeded during query execution: Not enough resources for query planning - too many subqueries or query is too complex.

I am using a WITH clause to create a view table. This table is populated from back-end Java and has a lot of rows (~900 rows). Below is the full query from my repository class:

from markets m join weights w on m.provider_id = w.providerId
join `data-services-200001.y eh on eh.id = m.event_id
join `data-services-200001.y` eh2 on eh2.id = m.event_parent_id
where date(eh.original_start_time) BETWEEN @from and @to and eh.version = 0
and eh2.version = 0
group by betting_type_id, event_part_id, event_id, eh.name, eh2.name, eh2.id
having total_weight >= 3

I think the main problem comes from the WITH clause, but I am not pretty sure how can fix this in an elegant manner.

Any tips would be appreciated!

Answer 1

The error you're facing appears before the actual execution of the query and it's caused by its complexity. Regularly, the 3 main reasons that cause complex queries are:

• a) Deeply nested and used repeatedly WITH clauses.
• b) Deeply nested and used repeatedly VIEWs.
• c) Lots of UNION ALL.

In your case, it happens because in the weights you have a lot of UNION ALL .

As I see your Query I would recommend you to Insert all the data into a table.

INSERT INTO `project.dataset.new_table`(weight, providerId)
VALUES(1,3000973)
VALUES(1,3000974)
VALUES(1,3000975)

After all the values are Inserted, you can use that table in the below query that you have. You need to change the values of project.dataset.new_table to your own.

markets as (
select distinct betting_type_id, event_part_id, event_id, provider_id, event_parent_id from `data-services-200001.x`
where date(event_original_start_time) BETWEEN @from AND @to and provider_id in (select providerId from `project.dataset.new_table`)
and sport_id = @sportId
and is_live = @isLive
and event_parent_id = @tournamentId
)
select betting_type_id, event_part_id, event_id, eh.name, eh2.name as tournament_name, eh2.id as tournament_id, sum(w.weight) as total_weight, STRING_AGG(cast(w.providerId as STRING)) as providers
from markets m join `project.dataset.new_table` w on m.provider_id = w.providerId
join `data-services-200001.y eh on eh.id = m.event_id
join `data-services-200001.y` eh2 on eh2.id = m.event_parent_id
where date(eh.original_start_time) BETWEEN @from and @to and eh.version = 0
and eh2.version = 0
group by betting_type_id, event_part_id, event_id, eh.name, eh2.name, eh2.id
having total_weight >= 3
