使用ElasticSearch Bulk动态更新和创建文档？(Using ElasticSearch Bulk to update and create documents dynamically?)

 我目前正在使用elasticsearch并每10分钟运行一次cron作业，它将从我的数据库中找到新创建/更新的数据并将其与elasticsearch同步。 但是，我想使用bulk同步而不是在索引中进行更新/创建文档的任意数量的请求。 我正在使用elasticsearch创建的elasticsearch.js库。 
 
 我遇到了两个我不确定如何处理的挑战： 
 
 
 
 如果文档存在，如何使用bulk更新文档，如果文档不在bulk内而不知道文档是否存在于索引中，则创建文档。 
 
 
 如何格式化大量JSON以通过bulk运行来更新/创建文档，因为bulk api期望以某种方式格式化主体。 
 

I'm currently using elasticsearch and running a cron job every 10 minutes that will find newly created/updated data from my DB and sync it with elasticsearch. However, I want to use bulk to sync instead of making and arbitrary amount of requests to update/create documents in an index. I'm using the elasticsearch.js library created by elasticsearch.
 
I face 2 challenges that I'm uncertain about how to handle:
 
 
 
How to use bulk to update a document if it exists and create a document if it doesn't within bulk without knowing if it exists in the index.
 
 
How to format a large amount of JSON to run through bulk to update/create the document because bulk api expects the body to be formatted a certain way.
