I do not need the count. When I try to paginate, this count query is executed automatically |

alexdd55976 |
for what do you need the count for? |

That is exactly what I am trying right now. |

and avoids some load on post query pagination |

super quick |

did you think about datatables, combined with ajax calls and json repsonses? |

Right now it would be just way faster to load 20k entries and throw them at the user than trying to paginate haha |

And until now it actually worked quite well. Absolutely not sure if a combined index is the right thing to use here. Just seemed to make sense here |

lol.. don't touch that :) |

oh, ok |

Was hoping to switch one day. But as the systems are productive and the ids are stored in thousands of entries and in lots of versioning/history I did not want to switch all |
| # |
Aug 22nd 2019, 11:10 |
alexdd55976 |
serious question. |
| # |
Aug 22nd 2019, 11:10 |
alexdd55976 |
you sure that a combined index is the way to go there? |
| # |
Aug 22nd 2019, 11:09 |
alexdd55976 |
was thinking about uuids .. but seems that uuids would make more sense, if used all over the place and not mixed up |
| # |
Aug 22nd 2019, 11:08 |
alexdd55976 |
i have a similar approach planed in my new project |
| # |
Aug 22nd 2019, 11:07 |
conehead |
it is a Unique Index combined with `model` and `foreign_key` |
| # |
Aug 22nd 2019, 11:07 |
alexdd55976 |
that explains longer response time |

Status can be linked to different entities. And some entities have a uuid and some have an id |
| # |
Aug 22nd 2019, 11:06 |
alexdd55976 |
so its a text fulltext index? |
| # |
Aug 22nd 2019, 11:06 |
conehead |
No, both CHAR(36), but sometimes the CHAR just stores the id |
| # |
Aug 22nd 2019, 11:05 |
alexdd55976 |
how can you have both? its a different datatype? |
| # |
Aug 22nd 2019, 11:05 |
conehead |
Which imho should not be a problem |
| # |
Aug 22nd 2019, 11:05 |
alexdd55976 |
thats a tough one |
| # |
Aug 22nd 2019, 11:05 |
conehead |
yes |
| # |
Aug 22nd 2019, 11:05 |
alexdd55976 |
? |
| # |
Aug 22nd 2019, 11:05 |
alexdd55976 |
> OR |
| # |
Aug 22nd 2019, 11:04 |
conehead |
The foreign_key might contain ids or uuids |
| # |
Aug 22nd 2019, 11:03 |
conehead |
Urgh...I got an idea |
| # |
Aug 22nd 2019, 11:03 |
conehead |
``` SELECT ( COUNT(*) ) AS `count` FROM documents Documents LEFT JOIN statuses Status ON ( Documents.id = (Status.foreign_key) ) ``` |
| # |
Aug 22nd 2019, 11:00 |
alexdd55976 |
so whta the current query? |
| # |
Aug 22nd 2019, 11:00 |
conehead |
@alexdd55976 yes I removed it and still takes 8 seconds. |
| # |
Aug 22nd 2019, 11:00 |
conehead |
@steinkel I can check but it is not a query I perform myself. |
| # |
Aug 22nd 2019, 11:00 |
alexdd55976 |
`LEFT JOIN statuses Status ON ( Status.model = 'Documents'` thats slows things down |
| # |
Aug 22nd 2019, 10:59 |
steinkel |
`->counter` would allow you to tweak the query for count() |
| # |
Aug 22nd 2019, 10:58 |

@conehead check this https://book.cakephp.org/3.0/en/orm/query-builder.html#returning-the-total-count-of-records |
| # |

When I remove that additional condition, SQL time is reduced from 22 seconds to 8 seconds for this query :S |
| # |
Aug 22nd 2019, 10:51 |
conehead |
Oh and yes the count is actually affected as there is a condition for the model field |
| # |

Yes I did. The query itself is working fine and fast. When passing the query to pagination, shit hits the fan |
