# Fiscal Event And Fiscal Event Post-processor Service Promotion
The fiscal event post-processor receives a collection of fiscal event lists and after processing those events it pushes them to the Mongo DB and Druid DB. Before deploying the fiscal event post-processor build to the respective environment, make sure you have ingested the updated druid config file to the Druid DB as per the instructions given [here](https://github.com/misdwss/iFix-Dev/blob/master/domain-services/fiscal-event-post-processor/README.md).
## **Fiscal Events Data Clean up**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.digit.org/public-finance/v2.3/platform/configuration/promotion-docs/fiscal-event-and-fiscal-event-post-processor-service-promotion.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
