pub enum OptimizationLevel {
None,
Default,
Full,
}
Expand description
Defines how many optimizations the query optimizer should apply.
Currently, the default value is OptimizationLevel::Full, as we are still searching for a subset that performs well on many queries. Once this subset has been identified, the default value will be OptimizationLevel::Default.
Variants§
None
No optimizations, except rewrites that are necessary for a working query.
Default
A balanced default optimization level. Suitable for simple queries or those handling modest data volumes.
Full
Runs all optimizations. Ideal for complex queries or those processing large datasets.
