[RFC]: Sql Statement Query Caching

[simon-mundy]

Proposed Version

0.6.0

Basic Information

PhpDb manually compiles each Select query for every single query, creating unnecessary overhead when a query itself will not change based on adapter/platform.

The intention of this proposal is to allow a caching mechanism which would determine if a Statement uses a Parameter Container and if so, store the compiled query in a cache that is user-determined. This still allows the database driver to correctly quote/execute data without needing to cache-bust regularly.

Proposal(s)

Sample pseudo code:-

$select->from('foo')->where([
    'c1' => null,
    'c2' => [1, 2, 3],
    new \Laminas\Db\Sql\Predicate\IsNotNull('c3'),
]);
// Cached string is 'SELECT "foo".* FROM "foo" WHERE "c1" IS NULL AND "c2" IN (?, ?, ?) AND "c3" IS NOT NULL'

$statement = $sql->prepareStatementForSqlObject($select, $storage); // where $storage is a PSR-6 compliant storage wrapper
$results = $statement->execute(); // Statement will use pre-prepared SQL string based on driver/adapter/platform

Appendix/Additional Info

PhpDb should be able to consume any PSR compliant cache that is registered in a container.
