Hi,
I have the key value pairs in the log message and I want to do data mapping before indexing the data to ElasticSearch.
**Sample Log Message 1: operation=1 timetaken=50**
**Sample Log Message 2: operation=2 timetaken=100**
I want the output in ElasticSearch to be as below.
```
{
{
"operation" : "ABC",
"timetaken" : "50"
},
{
"operation" : "XYZ",
"timetaken" : 100
}
}
```
I want to map operation values as 1 to ABC & 2 to XYZ . Is this possible with any filters ?

You could try using a kv filter to parse the message and then a translate fitler to map the values.
