Producing Solr JSON (array)
Hello,
I'm experimenting with Hop for producing an array of JSON objects like Indexing
with Update Handlers :: Apache Solr Reference Guide
<https://solr.apache.org/guide/solr/latest/indexing-guide/indexing-with-update-handlers.html#adding-multiple-json-documents>
<https://solr.apache.org/guide/solr/latest/indexing-guide/indexing-with-update-handlers.html#adding-multiple-json-documents>I
like JSON Output since it has "Nr. rows in a block" it blocks records into
bigger arrays.
However it creates a root object with array property, but I need just array
as root elem, and can't set Json block name empty to suppress it.
As an alternative I've checked Enhanced JSON Output. It can suppress root
object&property and yield a root array. It's fine. But I can't find how to
limit size of the block (created array). How I can set "Nr. rows in a block"
with Enhanced JSON Output?
Btw, isn't there a SolrJ transform for HOP?

Thanks Matt. I managed the downstream system to consume the existing
format.
Although, I discovered one bug during this experiment
https://issues.apache.org/jira/browse/SOLR-16811 open-source, you know.

To be honest I usually use Javascript to assemble more complex JSON
structures.
The ability in that transform to have start and end logic allows you to add
elements to arrays and so on.
Let me know if you need a particular example.
HTH,
Matt
