Getting Vistar Media Added to the Adopters page

On this page of the Parquet website - https://parquet.apache.org/adopters/

It mentions opening up an issue with a linked tweet to get added to the page.

We at Vistar Media have been working with Parquet for a while, and recently put up a tweet and blog post about it - https://twitter.com/vistarmedia/status/816342773465051137

I wanted to see if we could be added to the page of Adopters.

从 https://parquet.apache.org/adopters/ 上的 Parquet adopters 页面开始，查看现有 adopter 条目的呈现方式，以及 issue 中链接的 Vistar Media 推文。完成的标准是将 Vistar Media 连同相关参考链接添加到 adopters 页面。
