Best way to generate multivalue fields from streaming API

[Mike Thomsen]

Read this article and thought it could be interesting as a way to do
ingestion:

https://dzone.com/articles/solr-streaming-expressions-for-collection-auto-upd-1

Example from the article:

daemon(id="12345",

 runInterval="60000",

 update(users,

 batchSize=10,

 jdbc(connection="jdbc:mysql://localhost/users?user=root&password=solr",
sql="SELECT id, name FROM users", sort="id asc",
driver="com.mysql.jdbc.Driver")

)

What's the best way to handle a multivalue field using this API? Is
there a way to tokenize something returned in a database field?

Thanks,

Mike
