From the list of deployment concepts from above, using workers would mainly help with the **replication** part, and a little bit with the **restarts**, but you still need to take care of the others:

* **Security - HTTPS**
* **Running on startup**
* ***Restarts***
* Replication (the number of processes running)
* **Memory**
* **Previous steps before starting**

## Containers and Docker

        protected SearchResult search(String query, SearchRequestParams params, OptionalThing<FessUserBean> userBean) {
            int start = params.getStartPosition();
            int size = params.getPageSize();
            SearchResultBuilder builder = SearchResult.create();
            for (int i = start; i < start + size && i < allRecordCount; i++) {
                Map<String, Object> doc = new HashMap<>();

## Dynamic systems without restarting server

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.

```
api                   manage global HTTP API call specific features, such as throttling, authentication types, etc.
heal                  manage object healing frequency and bitrot verification checks
