update TCP stream with batchsize 10000 at once using update record

[#1]

Hi,

I am getting a plain json stream with '\n' delimiter through TCP.

I am listening to TCP using listenTCP, set batchsize to 10000.

My json is with variable values, ex:

{"a":"20180831","b":"b"}
{"a":"20180831","b":"b","c":"c"}

I want to add a partition_value attribute to every line in json stream at once, which should look like

The attribute a is always present in json, so I want to use partition_value in a

{"a":"20180831","b":"b","partition_value":"20180831"}
{"a":"20180831","b":"b","c":"c","partition_value":"20180831"}

I have used "UpdateRecord" processor

below are the configuration

UpdateRecord

JsonTreeReader

AvroSchemaRegistry

AvroRecordSetWriter

I used UpdateRecord -> jsontreereader ->avroschemaregistry

|_________ -> avrorecordsetwriter

Then I have used avrotojson

I am getting only one line as output, can you please suggest where it is happening wrong or let me know if there is a better way to do it

Thank you

{"a":"20180831","b":"b","c":null,"partition_value":"20180831"}
