      Description

      we are using flux to submit storm topology, for topology yml file, we need substitute variables, from https://github.com/apache/storm/tree/master/flux, it says variable can be substituted in format of ${variable.name}, my question is, in my case, variable is a list, and I only want to get first element of the list, how can I do it?

      I try to use ${variable.0} and ${variable}[0], it doesn't work, after substitution, the result is element_name.0 or element_name[0], which is not I expected(expected one should be element_name), please let me know how to specify the first element of a list in flux.
