Patrick Wiener updated STREAMPIPES-347:
---------------------------------------
Description:
*Context*
Rename multiple events field at once.
{code:java}
{
"time_stamp": 1234,
"sensor_id": "sensor1",
"sensor_measurement": 24.0
}
{code}
rename "sensor_id" -> "id", "sensor_measurement", "measurement": new event
{code:java}
{
"time_stamp": 1234,
"id": "sensor1",
"measurement": 24.0
}{code}
*Problem*
Currently, we do have a FieldRenamer implemented using Flink wrapper, yet only
allowing to rename one field at a time, i.e., renaming n fields requires a
sequence of #n FieldRenamer processors. In addition, this option is unavailable
when using lite version, i.e., standalone Java extensions.
*Solution*
Add FieldRenamer JVM processor using something like CollectionStaticProperty to
allow arbitrary number of mappings, where a user can select a mapping property
and add a new field name in a text field right next to it.
