	InterQueryBuiltinCache InterQueryBuiltinCacheConfig `json:"inter_query_builtin_cache"`
}

Config represents the configuration of the inter-query cache.

func ParseCachingConfig ¶

func ParseCachingConfig(raw []byte) (*Config, error)

ParseCachingConfig returns the config for the inter-query cache.

type InterQueryBuiltinCacheConfig ¶

type InterQueryBuiltinCacheConfig struct {
	MaxSizeBytes *int64 `json:"max_size_bytes,omitempty"`
}

InterQueryBuiltinCacheConfig represents the configuration of the inter-query cache that built-in functions can utilize.

type InterQueryCache ¶

type InterQueryCache interface {
	Get(key ast.Value) (value InterQueryCacheValue, found bool)
	Insert(key ast.Value, value InterQueryCacheValue) int
	Delete(key ast.Value)
	UpdateConfig(config *Config)
}

InterQueryCache defines the interface for the inter-query cache.

func NewInterQueryCache ¶

func NewInterQueryCache(config *Config) InterQueryCache
