Adding custom properties, that change during processing

@burning-papaya If you haven't made any progress yet, I think that you might be interested in this. What you described is achievable with Log4j2 params and unwrapping serializers.

@burning-papaya I don't see many other options than ThreadContext tbh.

If you're tied to Log4j2 and need to log these events with other appenders, custom MessageFactory and mixins for Message may be a way to go. Otherwise, you can use AsyncBatchDelivery directly and serialize your own classes instead of LogEvent.

@rfoltyns Thank you, for your reply.

Could you please elaborate on the last sentence (direct usage of AsyncBatchDelivery with my own class)? I have a class which i have to log, every field has to be written in elasticsearch separately for ease of searching (it's Kotlin data class):

@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
 data class RequestLog (
    @JsonProperty("verb") var verb: String = "",
    @JsonProperty("uri") var uri: String = "",
    @JsonProperty("query") var query: String = "",
    @JsonProperty("body") var body: String = "",
    @JsonProperty("io_type") var type: String = "OUT_REQUEST"
)

You can use parts of programmatic config test and use this library like this:

asyncBatchDelivery.add(indexName, itemSourceFactory.create(instanceOfYourClass, objectWriter));

ItemSourceFactory and AsyncBatchDelivery must be started explicitly in this case.
