Patch #33431
openBetter performance for Time entries without issue and activity filters
0%
Description
At the moment all time entry queries join issue and activities. If there is a large number of time entries and issues, this is a big performance issue.
Some of our customers have more than 500.000 time entries and even more issues. A query without a time filter requires minutes. With this attached patch this improves it to some seconds.
Issue and activity joins are only add, if they are required.
It would be great, to get this in Redmine.

My patch has problems with column sort order.
But I found the real problem now. It is a missing condition to project_id for Enumeration. I am working on a new patch to fix this problem. Please do not commit the current patch.

Nice feature, but we should have tests for this change.

Here is my new fixed version.
Adding
where("#{Enumeration.table_name}.project_id = #{TimeEntry.table_name}.project_id")
fixed the problem. But I moved activity join from base_scope to results_scope, because as I understood it, activity join is not required for totals and count.
I am not sure, how I can test this change with an additional test. Existing test should work, of course.

And again, now all tests are running.
With my test data, /time_entries without filters
- without patch: ActiveRecord: 345038.1ms
- with patch ActiveRecord: 6038.4ms
This is not perfect, but way better than before. At the moment I have no idea how it can be more improved. The problem is table layout of enumerations table.

2 years later, a new patch introduce skipping joins for count time entries, which are not required. Test added.
All tests run successful with this changes.

on the ther hand (in regard to #37962) this patch helped a lot under Redmine 4.2.8 (mysql 8):
time for time entries queries was reduced approx by 40% for me.
thank you!

We have hundreds of thousands of time entries and redmine became almost unusable recently, this patch made a huge difference to us. It would be great if it can be pushed into an upcoming release.

I have a problem with the v5 patch.
If you move an issue to another project, the project_id no longer matches the request and is ignored when displaying the numbers.
An example:
Issue 2982 belonged to project with ID = 8 when the time entry 34446 was created and then was moved in another project ID = 17
MariaDB [redmine_import]> select te.*,projects.id,enumerations.id,enumerations.project_id,enumerations.type,users.id,users.type,projects.id FROM time_entries AS te INNER JOIN `projects` ON `projects`.`id` = te.project_id INNER JOIN enumerations ON enumerations.id = te.activity_id AND enumerations.type = 'TimeEntryActivity' INNER JOIN users ON users.id = te.user_id AND users.type IN ('User', 'AnonymousUser') WHERE te.id=34446;
+-------+------------+-----------+---------+----------+-------+------------------------------------+-------------+------------+-------+--------+-------+---------------------+---------------------+---------+------+----+-----+------------+-------------------+----+------+----+
| id | project_id | author_id | user_id | issue_id | hours | comments | activity_id | spent_on | tyear | tmonth | tweek | created_on | updated_on | rate_id | cost | id | id | project_id | type | id | type | id |
+-------+------------+-----------+---------+----------+-------+------------------------------------+-------------+------------+-------+--------+-------+---------------------+---------------------+---------+------+----+-----+------------+-------------------+----+------+----+
| 34446 | 17 | 12 | 12 | 2982 | 4 | Fix alma container issue for devel | 172 | 2021-10-04 | 2021 | 10 | 40 | 2021-10-05 07:59:26 | 2021-10-05 07:59:26 | NULL | NULL | 17 | 172 | 8 | TimeEntryActivity | 12 | User | 17 |
+-------+------------+-----------+---------+----------+-------+------------------------------------+-------------+------------+-------+--------+-------+---------------------+---------------------+---------+------+----+-----+------------+-------------------+----+------+----+
1 row in set (0.001 sec)
So the DB queries was KO and doesn't display the good numbers, for an hotfix we just removed
def base_result_scope
base_scope.joins(:activity, :user)
.includes(:activity)
.left_join_issue
# XXX - remove to let time entry report working fine
# .where(activity_scope_sql)
end
