    • dataPath

      default String dataPath()
      The extra path for saving package data. For example, we have a package function://public/default/package@v0.1, it will save the meta to the path function/public/default/package/v0.1/meta, and save the data to the path function/public/default/package/v0.1. By default, we are using distributed log as the package storage, and it supports saving data at a directory. But some storage like filesystem don't have the similar ability, it needs another path for saving the data. This api provides the ability to support saving the data in another place. If you specify the data path as `/data`, the package will saved into function/public/default/package/v0.1/data.
      Returns:
      the data path
