Avro supports two encoding mechanisms – binary encoding, and JSON encoding. [1]
In other words, an Avro record, although normally represented as binary data,
can instead be represented as a JSON document.
I contributed an improvement to the Flink Avro connector to add support for
JSON-encoded Avro as part of FLINK-33058 [2], although this is not yet merged.
I must admit, I’m not familiar with OpenSearch or what the Flink OpenSearch
connector offers, so my apologies if I’m just adding noise to the conversation
here!
Kind regards
Dale

Hi, Praveen.
`OpenSearch supports writing data in the JSON format, but in Flink its default
data format is Avro JSON.`
I'm not sure what is the ` Avro JSON` means. In Opensearch connector, there are
multi formats it supports sucn as "avro", "format" and etc by adding
corresponding jars, and the default format[1] is "json" you want.
`OpenSearch Java Rest Client support writing the Java object directly to the
openSearch using the below code.`
Currently, the Opensearch connector connector always write the data
serialized[2]. You can modify here directly in Opensearch connector, re-package
it and try to use it.

Hello Team
Please helps to answer the below query.
OpenSearch supports writing data in the JSON format, but in Flink its default
data format is Avro JSON. What is the best practice to write data to Open
Search using Flink OpenSearch Connector? Do we need to manually convert Avro
JSON to JSON format or is there any in-built support in Flink to write JSON to
openSearch.
How can I write the existing complex nested JSON data into OpenSearch using the
Flink connector rather than writing each key-value(or filed/value).
OpenSearch Java Rest Client support writing the Java object directly to the
openSearch using the below code.
IndexRequest<UserDataObject> indexRequest =new
IndexRequest.Builder<UserDataObject>().index(index).document(indexData).build();
