+# Destination Elasticsearch
+
+This is the repository for the Elasticsearch destination connector in Java.
+For information about how to use this connector within Airbyte, see [the User Documentation](https://docs.airbyte.io/integrations/destinations/elasticsearch).
+
+## Local development
+
+#### Building via Gradle
+From the Airbyte repository root, run:
+```
+./gradlew :airbyte-integrations:connectors:destination-elasticsearch:build
+```
+
+#### Create credentials
+**If you are a community contributor**, generate the necessary credentials and place them in `secrets/config.json` conforming to the spec file in `src/main/resources/spec.json`.
+Note that the `secrets` directory is git-ignored by default, so there is no danger of accidentally checking in sensitive information.
+
+**If you are an Airbyte core member**, follow the [instructions](https://docs.airbyte.io/connector-development#using-credentials-in-ci) to set up the credentials.
+
+### Locally running the connector docker image
+
+#### Build
+Build the connector image via Gradle:
+```
+./gradlew :airbyte-integrations:connectors:destination-elasticsearch:airbyteDocker
+```
+When building via Gradle, the docker image name and tag, respectively, are the values of the `io.airbyte.name` and `io.airbyte.version` `LABEL`s in
+the Dockerfile.
+
+#### Run
+Then run any of the connector commands as follows:
+```
+docker run --rm airbyte/destination-elasticsearch:dev spec
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/destination-elasticsearch:dev check --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/destination-elasticsearch:dev discover --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/destination-elasticsearch:dev read --config /secrets/config.json --catalog /integration_tests/configured_catalog.json
+```
+
+## Testing
+We use `JUnit` for Java tests.
+
+### Unit and Integration Tests
+Place unit tests under `src/test/io/airbyte/integrations/destinations/elasticsearch`.
+
+#### Acceptance Tests
+Airbyte has a standard test suite that all destination connectors must pass. Implement the `TODO`s in
+`src/test-integration/java/io/airbyte/integrations/destinations/elasticsearchDestinationAcceptanceTest.java`.
+
+### Using gradle to run tests
+All commands should be run from airbyte project root.
+To run unit tests:
+```
+./gradlew :airbyte-integrations:connectors:destination-elasticsearch:unitTest
+```
+To run acceptance and custom integration tests:
+```
+./gradlew :airbyte-integrations:connectors:destination-elasticsearch:integrationTest
+```
+
+## Dependency Management
+
+### Publishing a new version of the connector
+You've checked out the repo, implemented a million dollar feature, and you're ready to share your changes with the world. Now what?
+1. Make sure your changes are passing unit and integration tests.
+1. Bump the connector version in `Dockerfile` -- just increment the value of the `LABEL io.airbyte.version` appropriately (we use [SemVer](https://semver.org/)).
+1. Create a Pull Request.
+1. Pat yourself on the back for being an awesome contributor.
+1. Someone from Airbyte will take a look at your PR and iterate with you to merge it into master.

+# Elasticsearch Destination
+
+Elasticsearch is a Lucene based search engine that's a type of NoSql storage.  
+Documents are created in an `index`, similar to a `table`in a relation database.  
+
+The documents are structured with fields that may contain nested complex structures.  
+[Read more about Elastic](https://elasticsearch.org/)  
+
+This connector maps an incoming `stream` to an Elastic `index`.  
+When using destination sync mode `append` and `append_dedup`, an `upsert` operation is performed against the Elasticsearch index.  
+When using `overwrite`, the records/docs are place in a temp index, then cloned to the target index. 
+The target index is deleted first, if it exists before the sync.
+
+The [ElasticsearchConnection.java](./src/main/java/io/airbyte/integrations/destination/elasticsearch/ElasticsearchConnection.java) 
+handles the communication with the Elastic server. 
+This uses the `elasticsearch-java` rest client from the Elasticsearch team -  
+[https://github.com/elastic/elasticsearch-java/](https://github.com/elastic/elasticsearch-java/)
+
+The [ElasticsearchAirbyteMessageConsumerFactory.java](./src/main/java/io/airbyte/integrations/destination/elasticsearch/ElasticsearchAirbyteMessageConsumerFactory.java) 
+contains the logic for organizing a batch of records and reporting progress. 
+
+The `namespace` and stream `name` are used to generate an index name.  
+The index is created if it doesn't exist, but no other index configuration is done at this time.  
+
+Elastic will determine the type of data by detection.  
+You can create an index ahead of time for field type customization.
+
+Basic authentication and API key authentication are supported.
+
+## Development 
+See the Elasticsearch client tests for examples on how to use the library.
