Answers.Text: I appreciate all of the time you've spent on this. I have a couple questions. But first, I made a second edit to hopefully provide all the information you'd need. For the `$categoryFieldId` and `$typeFieldId` -- would I need to get the IDs for all of my fields (name, address, type, country, etc.)? Is that what those variables are referring to? Or are those two variables referring to my two category fields (type and country)? Is `$categoryFieldId` supposed to be `$countryFieldId`?

Answers.Text: I updated the code but in order to get your fields I need the field handles not the field names.. but you could insert them by yourself as well. I provided all you need. `$typeFieldId` is the id of your relationField, you need it in order to fetch the related elements from those fields. Everything else is in the `craft_content` table that's why I asked for your field types. relations are not in the `craft_content` table

Answers.Text: This worked great! The only thing that was a little weird was that `type` was outputting duplicates of its title and also its title in all different languages. I ended up adding `DISTINCT` to `'GROUP_CONCAT(DISTINCT type.title) as typeTitle'` and an `AND` condition to `$query->join("content as type", "type.elementId = typeRelation.targetId AND type.locale = '$locale'");`. This seems to work but was just wondering if this seems correct? Thanks!

Answers.Text: Sry for responding so late. I noticed another bug yesterday and it took some time to fix it properly. With my first code you won't be able to fetch entries without any relations, read my edit to fix it. And indeed you are right, I forgot about the `locale`. I tried to include every important condition but I forgot that one. Please let me know if the code is fast enough

Answers.Body: <p>Assuming you're referring to Craft 2, the EntryModels that get returned to a template do have a significant memory overhead attached to them you're probably running into.  Doing the math, even bumping your php.ini <code>memory_limit</code> up to 256M is only going to get your around 260 results coming back with your given fields/configuration.</p>
  
  <p>It's one of the big things we first improved in the upcoming <a href="https://craftcms.com/3" rel="nofollow noreferrer">Craft 3</a>.</p>
  
  <p>In the meantime, you've got a couple of options:</p>
  
  <ol>
  <li><p>Paginate the results so you can do them in smaller batches.</p></li>
  <li><p>AJAX/lazy load the results over multiple requests in smaller batches.</p></li>
  <li><p>Write a <a href="https://pluginfactory.io" rel="nofollow noreferrer">plugin</a> (<a href="https://craftcms.com/docs/plugins" rel="nofollow noreferrer">https://craftcms.com/docs/plugins</a>) that bypasses Craft's Element/Model loading and queries the database directly and returns only the data you explicitly need back to the template, without all of the model overheard.</p></li>

Answers.Text: Thank you for your suggestions. It seems like option 3 is the way to go. We're already implementing option 1 on our normal page, and that's the issue our client is trying to get around (option 2 would be similar).
  
  So could I just store that data in a JSON file or something that updates every time a user edits or creates a new entry? Would I then just pass that data to the template?

Answers.Text: You could store it statically and update it as needed.  If it's updated often, might just be easier to return the massaged data straight from the database, though.

Comments.Text: It would be good to know a little bit more about your structure. Normally craft should not have such huge problems with 700 entries unless you created many fields thus your content table is really huge. Do you need the entire entry with all relations and all fields or do you only need some of them? You could eventually thinking about making your custom db query and fetch the raw content+element table record - in order to boost your performance if you only need information like the title, some text fields and string content.

  ### Answer by username_1 on 2017-11-15. Score: 2 | Accepted answer
  
  1. Read some pages in the craft docs that username_2 linked to get to know the basic structure where to place your files
  2. Go to [Pluginfactory](https://pluginfactory.io/) and create a plugin, you only have to check the "Variables" light switch to generate a `PluginNameVariables` file
  3. Download the files and place them in your `craft/app/>>pluginHandle<<` folder like it is stated in the docs
  4. Install the plugin
  5. copy the following code into your `craft/plugins/>>pluginHandle<</variables/>>pluginHandle<<Variables.php`
  
     ```
     /**
      * @return mixed
      */
     public function getAllEntries(){
         // I want to create the code with the best possible performance, so I would
         // like to avoid using $field = craft()->fields()->getFieldByHandle();
         // and instead inserting the id directly, my ids are 13 and 14
         $countryFieldId = 13;
         $typeFieldId = 14;
         // insert your local here
         $locale = 'de';
         // insert your section handle, for my test system it is news
         $sectionHandle = 'news';
         $dbCommand = craft()->db->createCommand();
         // select all your needed fields, I don't want to loop through your field layout since
         // that would result in multiple queries and I want to have the best possible performance
         $dbCommand->select([
             'country.title as countryTitle',
             'GROUP_CONCAT(type.title) as typeTitle',
             // content is your entry
             'content.title as elementTitle',
             'content.field_body as elementText'
         ]);
         $dbCommand->from('elements as elements');
         $dbCommand->join('elements_i18n as elements_i18n', 'elements_i18n.elementId = elements.id');
         $dbCommand->join('content as content', 'content.elementId = elements.id');
         $dbCommand->join('entries as entries', 'entries.id = elements.id');
         $dbCommand->join('sections as sections', 'sections.id = entries.sectionId');
         $dbCommand->leftJoin('structures as structures', 'structures.id = sections.structureId');
         $dbCommand->leftJoin('structureelements as structureelements', '(structureelements.structureId = structures.id) AND (structureelements.elementId = entries.id)');
         $dbCommand->setGroup('elements.id');
  
         $dbCommand->andWhere(array(
             'sections.handle'   => $sectionHandle,
             'elements_i18n.locale'  => $locale,
             'content.locale'  => $locale,
             'elements.enabled'  => 1,
             'elements_i18n.enabled'  => 1,
             // you can check here for entries.expiryDate and these things here as well
         ));
         $dbCommand->order('postDate DESC');
         $dbCommand->setGroup('elements.id');
  
         $dbCommand->leftJoin("relations typeRelation", "typeRelation.sourceId = elements.id");
         $dbCommand->join("relations countryRelation", "countryRelation.sourceId = elements.id");
         $dbCommand->andWhere(array(
             'countryRelation.fieldId' => $countryFieldId
         ));
         $dbCommand->andWhere(array(
             'typeRelation.fieldId' => $typeFieldId
         ));
         $dbCommand->join("content as country", "country.elementId = countryRelation.targetId");
         $dbCommand->join("content as type", "type.elementId = typeRelation.targetId");
  
         $elements = $dbCommand->queryAll();
  
         return $elements;
     }
  
     ```
  6. read the comments, try to follow the code and change the values (change ids, select values, fields and such)
  7. in order to fetch the entries in your template you need to
  
     ```
     {% set entries = craft.test.getAllEntries() %}
     {% for entry in entries %}
         <pre>
             {{ dump(entry) }}
         </pre>
         {% set types = entry.typeTitle|split(',') %}
         <pre>
             {{ dump(types) }}
         </pre>
     {% endfor %}
  
     ```
  
  please let me know if you need help
  
  **Edit**  
  I made some more tests and noticed you won't fetch any entries with no relations. So please change this
  
  ```
  $dbCommand->leftJoin("relations typeRelation", "typeRelation.sourceId = elements.id");
  $dbCommand->join("content as type", "type.elementId = typeRelation.targetId");
  $dbCommand->andWhere(array(
      'typeRelation.fieldId' => $typeFieldId
  ));
  
  ```
  
  to this
  
  ```
  $dbCommand->leftJoin("relations typeRelation", "typeRelation.sourceId = elements.id AND (typeRelation.fieldId = $typeFieldId)");
  // join content where the ids match or where the target is null in order to get entries without relation
  $dbCommand->leftJoin("content as type", "type.elementId = typeRelation.targetId OR typeRelation.targetId = null ");
  
  ```
  
  And of course add your `language` param

This seems to work but was just wondering if this seems correct? Thanks!  
  > **username_1**: Sry for responding so late. I noticed another bug yesterday and it took some time to fix it properly. With my first code you won't be able to fetch entries without any relations, read my edit to fix it. And indeed you are right, I forgot about the `locale`. I tried to include every important condition but I forgot that one. Please let me know if the code is fast enough

  Assuming you're referring to Craft 2, the EntryModels that get returned to a template do have a significant memory overhead attached to them you're probably running into. Doing the math, even bumping your php.ini `memory_limit` up to 256M is only going to get your around 260 results coming back with your given fields/configuration.
  
  It's one of the big things we first improved in the upcoming [Craft 3](https://craftcms.com/3).
  
  In the meantime, you've got a couple of options:
  
  1. Paginate the results so you can do them in smaller batches.
  2. AJAX/lazy load the results over multiple requests in smaller batches.
  3. Write a [plugin](https://pluginfactory.io) (<https://craftcms.com/docs/plugins>) that bypasses Craft's Element/Model loading and queries the database directly and returns only the data you explicitly need back to the template, without all of the model overheard.
  
  > **Comments:**
  > **username_0**: Thank you for your suggestions. It seems like option 3 is the way to go. We're already implementing option 1 on our normal page, and that's the issue our client is trying to get around (option 2 would be similar).  So could I just store that data in a JSON file or something that updates every time a user edits or creates a new entry? Would I then just pass that data to the template?  
  > **username_2**: You could store it statically and update it as needed.  If it's updated often, might just be easier to return the massaged data straight from the database, though.
