Class LevelDbIndex

constructor

• new LevelDbIndex(): LevelDbIndex

  Returns LevelDbIndex

deletedFileNumbers

filesByIndex

ldbFileIndexes

logFileIndexes

totalFiles

• get totalFiles(): number

  Total number of files in the index

  Returns number

findPotentialFilesForKey

• findPotentialFilesForKey(key: string): (ILevelDbFileIndex | ILevelDbLogIndex)[]

  Find files that might contain a specific key based on key range metadata. Returns files in priority order (LOG files first, then LDB by level).

  Note: This is a heuristic - if key ranges aren't available from manifest, all files are considered potential matches.

  Parameters

  • key: string

  Returns (ILevelDbFileIndex | ILevelDbLogIndex)[]

initFromManifest

• initFromManifest(
      ldbFiles: IFile[],
      logFiles: IFile[],
      newFileLevel?: number[],
      newFileNumber?: number[],
      newFileSmallest?: string[],
      newFileLargest?: string[],
      deletedFileNumber?: number[],
  ): void

  Initialize the index from manifest metadata. This does NOT load any file contents - just organizes metadata.

  Parameters

  • ldbFiles: IFile[]
  • logFiles: IFile[]
  • OptionalnewFileLevel: number[]
  • OptionalnewFileNumber: number[]
  • OptionalnewFileSmallest: string[]
  • OptionalnewFileLargest: string[]
  • OptionaldeletedFileNumber: number[]

  Returns void
