xdmp.externalBinaryPath

xdmp.externalBinaryPath(
   source as binary()
) as String?

Summary

Return the path to the external file associated with an external binary document.

Parameters
source The external binary node for which to retrieve the external file path.

Usage Notes

If the source binary node does not represent an external binary binary document, XDMP-ARG is thrown. That is, the source binary node must have been created by xdmp:external-binary. Use xdmp:binary-is-external to test whether or not a node represents an external binary.

The external binary format is best suited for read-only content managed external to MarkLogic Server. If the content is changed externally, the Compressed Tree Cache (CTC) should be cleared across the entire cluster, since the MarkLogic Server will not automatically reload the binary into the CTC.

Example

xdmp.externalBinaryPath(
  cts.doc("/movies/external-movie-1.mp4").xpath("/binary()"));

  => /space/binaries/movies/movie-1.mp4
