Simplified cache manager for common operations

Implementations

impl CacheManager

pub fn new(max_size: usize) -> Self

Create a new cache manager with separate plan and result caches

pub fn with_separate_limits( plan_cache_size: usize, result_cache_size: usize, ) -> Self

Create cache manager with different limits for plans and results

pub fn get_or_create<F>( &self, query: &str, creator: F, ) -> Result<String, String>

where F: FnOnce() -> Result<String, String>,

Get or create cached query plan Note: The creator function should return the parsed query, not execute it

pub fn get_result( &self, signature: &QuerySignature, ) -> Option<(Vec<Row>, CombinedSchema)>

Get cached query result

pub fn insert_result( &self, signature: QuerySignature, rows: Vec<Row>, schema: CombinedSchema, tables: HashSet<String>, )

Insert query result into cache

pub fn invalidate_table(&self, table_name: &str)

Invalidate all plans and results referencing a table

pub fn clear(&self)

Clear all cached plans and results

pub fn plan_stats(&self) -> CacheStats

Get plan cache statistics

pub fn result_stats(&self) -> CacheStats

Get result cache statistics

pub fn stats(&self) -> CacheStats

Get combined cache statistics (for backwards compatibility)
