In filter

[mznet]

Druid has various filters and in filter is one of them. Using in filters, template or variable separated by comma can be used as query parameter. The value is transformed to array.

I referred to In Filter from this document(http://druid.io/docs/latest/querying/filters.html).

• With in filter, template or variable can be used to query

• With in filter, value which are separated by comma can be used to query

@shcarrico Thank you for your review. I just wonder why the commit message format should be applied? Other PR didn't be composed with the format.

@shcarrico you should be able to squash all commits into one during the merge. There is a feature in github that would allow you to squash a PR. https://help.github.com/articles/about-pull-request-merges/#squash-and-merge-your-pull-request-commits
