Database Administrators Asked by wavrik on October 28, 2021
I will detail my problem in good detail. I have a marketplace application so I make a decision to make a multitenant per schema approach. I like this approach because of the isolation of data, but I’m facing so many problems that I want to get out of this.
In the first days it is good to go but today I have 3500 schemas and is really hard to make maintenance. I make a famous approach with schemas with a master table that use Inheritance on all my child ( tenants ) tables, but not all, just a few.
So when I execute this simple select in a master.table
SELECT bra_f.file_id, bra_f.file_path
FROM master.bra_file bra_f
WHERE bra_f.product_id = :productId
AND bra_f.active = true
It takes to me 7 seconds to perform this simple query with a GLOBAL SEQUENCE from product_id that I put on all child bra_product tables.
My problem is similar to this:
https://stackoverflow.com/questions/62013115/improve-postgresql-select-performance-in-a-parent-table-inheritance/62017449#62017449
I really thinking seriously to put all my data in shared tables because and change all my project. I am really sad about my decision to make a multi-tenant schema approach.
What I must do to make this performance good? and don’t lose my precious time to refactor my project.
This is my explanation, I can’t perform exactly in the database because I make a loop on each product_id on my laravel backend and I can’t use this in Postgres.
Example this is my loop:
public function getMasterProdFullTeste($productList)
{
$size = count($productList);
for ($i = 0; $i < $size; $i++) {
$productList[$i]->srcimglist = $this->mdFile->getMasterImageByProductTeste($productList[$i]);
}
dd($productList);
return $productList;
}
And this is my function that executes on my model:
public function getMasterImageByProductTeste($product)
{
return DB::select('SELECT bra_f.file_id, bra_f.file_path
FROM master.bra_file bra_f
WHERE bra_f.product_id = :productId
AND bra_f.active = true', ['productId' => $product->product_id]);
}
Example this is the query that execute in each loop:
SELECT bra_f.file_id, bra_f.file_path
FROM master.bra_file bra_f
WHERE bra_f.product_id = :productId
AND bra_f.active = true;
If I use EXPLAIN it gives me this:
