Obsolete analytics tables are not deleted during analytics update

Dear devs,

it seems like the analytics table update does not remove data/tables of years,
that are no longer valid.

Since dataValues can be deleted via api in batch, it can happen that dataValues
for a whole year get deleted. Of course these years should not show up in the
analytics (pivot, chart etc...) any more. However, those obsolete tables seem to
remain in the database after running the analytics update. Of course they could
be remove manually, but this is not applicable in a nightly load scenario.

I did empty the cache and checked catalina.out, but I can't find an error. In
the database the dataValues table remains with only the years, that were not
deleted, so the deletion obviously worked. But the obsolete analytics tables
(e.g. analytics_2012) are still there and populated. You can verify in the
attached excerpt from catalina.out: only years >= 2016 were (correctly) updated,
deleted years <= 2015 remained untouched.

This is quite serious as it results into wrong statistics, if not detected. I
just discovered this because of a major clean-up activity - if there are only
very few years affected, users might not even notice that they are reporting
deleted data.

Currently running on 2.22, build 21765, Standard Ubuntu 14.04 & OracleJava 8.

Thanks for checking on that,

Uwe

Hi, I can only support/confirm what Uwe is saying here - I just experieced the same thing this morning: deleted data for one year, ran analytics, and the deleted data is still displayed.

Hi Uwe,

will work on this.

Short-term workaround is to go to data admin > maintenance and click Clear analytics tables.

Hi Lars,

thanks for taking this over. If there was an api for clearing the analytics
table, which is giving back a result (unlike the one for updating the analytics
tables), that would already be a sufficient solution for nightly runs. Then I
could always delete the analytics tables before generating them afresh. Whatever
is easier for you to implement ...

You have interesting working hours :slight_smile:

Hi Uwe

We have an API for clearing analytics cache [1], I’m sure we can make one for clearing analytics tables also. Would you mind creating a blueprint for us? and give me the link, and I will assign the proper people.

Hi Morten and Lars,

thanks for the quick reaction. One more question on this: does the api for creating analytics work delta-sensitive (update only the changed years) or does it always rebuild the complete set of aggregates? If it has a delta mechanism, you might still want to consider doing Lars' blueprint to avoid lenghty aggregation runs every night ...

Regards,

Uwe
