  • Method Details

    • delete

      io.reactivex.rxjava3.core.Completable delete(String libraryName)
      Deletes library. Error is thrown if library doesn't exist.
      Parameters:
      libraryName - library name
    • dump

      io.reactivex.rxjava3.core.Single<byte[]> dump()
      Returns serialized state of all libraries.
      Returns:
      serialized state
    • flush

      io.reactivex.rxjava3.core.Completable flush()
      Deletes all libraries.
    • kill

      io.reactivex.rxjava3.core.Completable kill()
      Kills currently executed functions. Applied only to functions which don't modify data.
    • list

      io.reactivex.rxjava3.core.Single<List<FunctionLibrary>> list()
      Returns information about libraries and functions per each.
      Returns:
      list of libraries
    • list

      io.reactivex.rxjava3.core.Single<List<FunctionLibrary>> list(String namePattern)
      Returns information about libraries and functions per each by name pattern.

      Supported glob-style patterns: h?llo matches hello, hallo and hxllo h*llo matches hllo and heeeello h[ae]llo matches hello and hallo, but not hillo

      Parameters:
      namePattern - name pattern
      Returns:
      list of libraries
    • load

      io.reactivex.rxjava3.core.Completable load(String libraryName, String code)
      Loads a library. Error is thrown if library already exists.
      Parameters:
      libraryName - library name
      code - function code
    • loadAndReplace

      io.reactivex.rxjava3.core.Completable loadAndReplace(String libraryName, String code)
      Loads a library and overwrites existing library.
      Parameters:
      libraryName - library name
      code - function code
    • restore

      io.reactivex.rxjava3.core.Completable restore(byte[] payload)
      Restores libraries using their state returned by dump() method. Restored libraries are appended to the existing libraries and throws error in case of collision.
      Parameters:
      payload - serialized state
    • restoreAndReplace

      io.reactivex.rxjava3.core.Completable restoreAndReplace(byte[] payload)
      Restores libraries using their state returned by dump() method. Restored libraries are appended to the existing libraries.
      Parameters:
      payload - serialized state
    • restoreAfterFlush

      io.reactivex.rxjava3.core.Completable restoreAfterFlush(byte[] payload)
      Restores libraries using their state returned by dump() method. Deletes all existing libraries before restoring.
      Parameters:
      payload - serialized state
    • stats

      io.reactivex.rxjava3.core.Single<FunctionStats> stats()
      Returns information about currently running Redis function and available execution engines.
      Returns:
      function information
