Static Methods
-
analyzeEfficiency(
DatabaseStats stats) → DatabaseEfficiency - / Analyzes database efficiency and returns structured metrics.
-
analyzeUsage(
DatabaseStats stats) → String - Analyzes current database usage and returns a formatted string report.
-
calculateMapSize(
{required int expectedEntries, required int averageKeySize, required int averageValueSize, double overheadFactor = defaultOverheadFactor}) → int - Calculates required map size based on expected data volume.
-
calculateMaxEntries(
{required int mapSize, required int averageKeySize, required int averageValueSize, double overheadFactor = defaultOverheadFactor}) → int - Calculates the maximum possible entries for a given map size.
Constants
- defaultOverheadFactor → const double
- Default overhead factor for B+ tree structure and future growth. A factor of 1.5 means 50% extra space is reserved for the B+ tree structure.
- minMapSize → const int
- Minimum map size in bytes (1MB). The database cannot be smaller than this value.
