+# geonames-dump-producer
+This small scripts streams the [geonames dump](http://download.geonames.org/export/dump/allCountries.zip) form the internet to kafka. 
+
+## SplitterTransformer
+The SplitterTransformer split the string data into logical chunks. It will generate one chunk for each line separated by \n.
+
+## GeonamesNormalizerTransformer
+The GeonamesNormalizerTransformer normalizes the data from geonames and streams the result to kafka `geolinker` topic.
+
+## Docker
+To build the image use the following command. The container based on the [histub/ node-kafka-docker-base](https://source.dodis.ch/histhub/node-kafka-docker-base).
+```bash
+docker build -t source.dodis.ch:4577/histhub/geonames-dump-producer .
+# Upload to the registry
+docker push source.dodis.ch:4577/histhub/geonames-dump-producer
+```
+## CD
+We have a build pipeline in gitlab. So manually building of the image is not longer necessary. 
+
+## Deploy to k8
+This streaming app is part of the [data helm chart](https://source.dodis.ch/histhub/charts/tree/master/charts/data).

+# linker
+The linker is a [kafka sink](https://docs.confluent.io/current/connect/kafka-connect-elasticsearch/index.html) for the [neo4j](https://neo4j.com/) graph database. It consumes messages from the `linker` topic and writes them to the database.
+
+## Neo4jStreamWriter
+The Neo4jStreamWriter consumes a stream of kafka messages and writes the content of the message to the database. It is very simple and can handle backpressure.
+
+## Docker
+To build the image use the following command. The container is based on the [histub/ node-kafka-docker-base](https://source.dodis.ch/histhub/node-kafka-docker-base).
+```bash
+docker build -t source.dodis.ch:4577/histhub/linker .
+# Upload to the registry
+docker push source.dodis.ch:4577/histhub/linker
+```
+## CD
+We have a build pipeline in gitlab. So manual building of the image is no longer necessary. 
+
+## Deploy to k8
+This streaming app is part of the [deploy geolinker helm chart](https://source.dodis.ch/histhub/deploy-geolinker/wikis/deployment-manual#linker).
