Availability and prerequisites
editThis connector is available as a managed connector in Elastic versions 8.5.0 and later. To use this connector natively in Elastic Cloud, satisfy all managed connector requirements.
This connector has no additional prerequisites beyond the shared requirements, linked above.
Compatibility
editThis connector is compatible with MySQL 5.6 and later.
The connector is also compatible with MariaDB databases compatible with the above.
The data source and your Elastic deployment must be able to communicate with each other over a network.
Create a MySQL connector
editUse the UI
editTo create a new MySQL connector:
- In the Kibana UI, navigate to the Search → Content → Connectors page from the main menu, or use the global search field.
- Follow the instructions to create a new native MySQL connector.
For additional operations, see Connectors UI in Kibana.
Use the API
editYou can use the Elasticsearch Create connector API to create a new native MySQL connector.
For example:
resp = client.connector.put( connector_id="my-{service-name-stub}-connector", index_name="my-elasticsearch-index", name="Content synced from {service-name}", service_type="{service-name-stub}", is_native=True, ) print(resp)
const response = await client.connector.put({ connector_id: "my-{service-name-stub}-connector", index_name: "my-elasticsearch-index", name: "Content synced from {service-name}", service_type: "{service-name-stub}", is_native: true, }); console.log(response);
PUT _connector/my-mysql-connector { "index_name": "my-elasticsearch-index", "name": "Content synced from MySQL", "service_type": "mysql", "is_native": true }
You’ll also need to create an API key for the connector to use.
The user needs the cluster privileges manage_api_key
, manage_connector
and write_connector_secrets
to generate API keys programmatically.
To create an API key for the connector:
-
Run the following command, replacing values where indicated. Note the
id
andencoded
return values from the response:resp = client.security.create_api_key( name="my-connector-api-key", role_descriptors={ "my-connector-connector-role": { "cluster": [ "monitor", "manage_connector" ], "indices": [ { "names": [ "my-index_name", ".search-acl-filter-my-index_name", ".elastic-connectors*" ], "privileges": [ "all" ], "allow_restricted_indices": False } ] } }, ) print(resp)
const response = await client.security.createApiKey({ name: "my-connector-api-key", role_descriptors: { "my-connector-connector-role": { cluster: ["monitor", "manage_connector"], indices: [ { names: [ "my-index_name", ".search-acl-filter-my-index_name", ".elastic-connectors*", ], privileges: ["all"], allow_restricted_indices: false, }, ], }, }, }); console.log(response);
POST /_security/api_key { "name": "my-connector-api-key", "role_descriptors": { "my-connector-connector-role": { "cluster": [ "monitor", "manage_connector" ], "indices": [ { "names": [ "my-index_name", ".search-acl-filter-my-index_name", ".elastic-connectors*" ], "privileges": [ "all" ], "allow_restricted_indices": false } ] } } }
-
Use the
encoded
value to store a connector secret, and note theid
return value from this response:resp = client.connector.secret_post( body={ "value": "encoded_api_key" }, ) print(resp)
const response = await client.connector.secretPost({ body: { value: "encoded_api_key", }, }); console.log(response);
POST _connector/_secret { "value": "encoded_api_key" }
-
Use the API key
id
and the connector secretid
to update the connector:resp = client.connector.update_api_key_id( connector_id="my_connector_id>", api_key_id="API key_id", api_key_secret_id="secret_id", ) print(resp)
const response = await client.connector.updateApiKeyId({ connector_id: "my_connector_id>", api_key_id: "API key_id", api_key_secret_id: "secret_id", }); console.log(response);
PUT /_connector/my_connector_id>/_api_key_id { "api_key_id": "API key_id", "api_key_secret_id": "secret_id" }
Refer to the Elasticsearch API documentation for details of all available Connector APIs.

Known issues
editThis connector has the following known issues:
-
Upgrading from a tech preview connector (8.7 or earlier) to 8.8 will cause the MySQL connector configuration to be invalid.
MySQL connectors prior to 8.8 can be missing some configuration fields that are required for the connector to run. If you would like to continue using your MySQL connector after upgrading from 8.7 or earlier, run the script below to fix your connector’s configuration. This will populate the configuration with the missing fields. The auxilliary information needed for the configuration will then be automatically added by by the self-managed connector.
resp = client.update( index=".elastic-connectors", id="connector_id", doc={ "configuration": { "tables": { "type": "list", "value": "*" }, "ssl_enabled": { "type": "bool", "value": False }, "ssl_ca": { "type": "str", "value": "" }, "fetch_size": { "type": "int", "value": 50 }, "retry_count": { "type": "int", "value": 3 } } }, ) print(resp)
const response = await client.update({ index: ".elastic-connectors", id: "connector_id", doc: { configuration: { tables: { type: "list", value: "*", }, ssl_enabled: { type: "bool", value: false, }, ssl_ca: { type: "str", value: "", }, fetch_size: { type: "int", value: 50, }, retry_count: { type: "int", value: 3, }, }, }, }); console.log(response);
POST /.elastic-connectors/_update/connector_id { "doc" : { "configuration": { "tables": { "type": "list", "value": "*" }, "ssl_enabled": { "type": "bool", "value": false }, "ssl_ca": { "type": "str", "value": "" }, "fetch_size": { "type": "int", "value": 50 }, "retry_count": { "type": "int", "value": 3 } } } }
-
Upgrading to 8.8 does not migrate MySQL sync rules.
After upgrading, you must re-create your sync rules.
See Known issues for any issues affecting all connectors.
Documents and syncs
editThe following describes the default syncing behavior for this connector. Use sync rules and ingest pipelines to customize syncing for specific indices.
All records in the MySQL database included in your connector configuration are extracted and transformed into documents in your Elasticsearch index.
- For each row in your MySQL database table, the connector creates one Elasticsearch document.
- For each column, the connector transforms the column into an Elasticsearch field.
- Elasticsearch dynamically maps MySQL data types to Elasticsearch data types.
- Tables with no primary key defined are skipped.
-
Field values that represent other records are replaced with the primary key for that record (composite primary keys are joined with
_
).
The Elasticsearch mapping is created when the first document is created.
Each sync is a "full" sync.
For each MySQL row discovered:
- If it does not exist, the document is created in Elasticsearch.
- If it already exists in Elasticsearch, the Elasticsearch document is replaced and the version is incremented.
- If an existing Elasticsearch document no longer exists in the MySQL table, it is deleted from Elasticsearch.
- Files bigger than 10 MB won’t be extracted
- Permissions are not synced by default. All documents indexed to an Elastic deployment will be visible to all users with access to that Elastic Deployment.
Sync rules
editThe following sections describe Sync rules for this connector.
Basic sync rules are identical for all connectors and are available by default.
Advanced rules for MySQL can be used to pass arbitrary SQL statements to a MySQL instance.
You need to specify the tables used in your custom query in the "tables" field.
For example:
[ { "tables": ["table1", "table2"], "query": "SELECT ... FROM ..." } ]
When using advanced rules, a query can bypass the configuration field tables
.
This will happen if the query specifies a table that doesn’t appear in the configuration.
This can also happen if the configuration specifies *
to fetch all tables while the advanced sync rule requests for only a subset of tables.

Availability and prerequisites
editThis connector is available as a managed connector in Elastic versions 8.5.0 and later. To use this connector natively in Elastic Cloud, satisfy all managed connector requirements.
This connector is also available as a self-managed connector from the Elastic connector framework. To use this connector as a self-managed connector, satisfy all self-managed connector requirements.
This connector has no additional prerequisites beyond the shared requirements, linked above.
Create a MySQL connector
editUse the UI
editTo create a new MySQL connector:
- In the Kibana UI, navigate to the Search → Content → Connectors page from the main menu, or use the global search field.
- Follow the instructions to create a new MySQL self-managed connector.
Use the API
editYou can use the Elasticsearch Create connector API to create a new self-managed MySQL self-managed connector.
For example:
resp = client.connector.put( connector_id="my-{service-name-stub}-connector", index_name="my-elasticsearch-index", name="Content synced from {service-name}", service_type="{service-name-stub}", ) print(resp)
const response = await client.connector.put({ connector_id: "my-{service-name-stub}-connector", index_name: "my-elasticsearch-index", name: "Content synced from {service-name}", service_type: "{service-name-stub}", }); console.log(response);
PUT _connector/my-mysql-connector { "index_name": "my-elasticsearch-index", "name": "Content synced from MySQL", "service_type": "mysql" }
You’ll also need to create an API key for the connector to use.
The user needs the cluster privileges manage_api_key
, manage_connector
and write_connector_secrets
to generate API keys programmatically.
To create an API key for the connector:
-
Run the following command, replacing values where indicated. Note the
encoded
return values from the response:resp = client.security.create_api_key( name="connector_name-connector-api-key", role_descriptors={ "connector_name-connector-role": { "cluster": [ "monitor", "manage_connector" ], "indices": [ { "names": [ "index_name", ".search-acl-filter-index_name", ".elastic-connectors*" ], "privileges": [ "all" ], "allow_restricted_indices": False } ] } }, ) print(resp)
const response = await client.security.createApiKey({ name: "connector_name-connector-api-key", role_descriptors: { "connector_name-connector-role": { cluster: ["monitor", "manage_connector"], indices: [ { names: [ "index_name", ".search-acl-filter-index_name", ".elastic-connectors*", ], privileges: ["all"], allow_restricted_indices: false, }, ], }, }, }); console.log(response);
POST /_security/api_key { "name": "connector_name-connector-api-key", "role_descriptors": { "connector_name-connector-role": { "cluster": [ "monitor", "manage_connector" ], "indices": [ { "names": [ "index_name", ".search-acl-filter-index_name", ".elastic-connectors*" ], "privileges": [ "all" ], "allow_restricted_indices": false } ] } } }

- If it does not exist, the document is created in Elasticsearch.
- If it already exists in Elasticsearch, the Elasticsearch document is replaced and the version is incremented.
- If an existing Elasticsearch document no longer exists in the MySQL table, it is deleted from Elasticsearch.
Deployment using Docker
editYou can deploy the MySQL connector as a self-managed connector using Docker. Follow these instructions.
Step 1: Download sample configuration file
Download the sample configuration file. You can either download it manually or run the following command:
curl https://raw.githubusercontent.com/elastic/connectors/main/config.yml.example --output ~/connectors-config/config.yml
Remember to update the --output
argument value if your directory name is different, or you want to use a different config file name.
Step 2: Update the configuration file for your self-managed connector
Update the configuration file with the following settings to match your environment:
-
elasticsearch.host
-
elasticsearch.api_key
-
connectors
If you’re running the connector service against a Dockerized version of Elasticsearch and Kibana, your config file will look like this:
# When connecting to your cloud deployment you should edit the host value elasticsearch.host: http://host.docker.internal:9200 elasticsearch.api_key: <ELASTICSEARCH_API_KEY> connectors: - connector_id: <CONNECTOR_ID_FROM_KIBANA> service_type: mysql api_key: <CONNECTOR_API_KEY_FROM_KIBANA> # Optional. If not provided, the connector will use the elasticsearch.api_key instead
Using the elasticsearch.api_key
is the recommended authentication method. However, you can also use elasticsearch.username
and elasticsearch.password
to authenticate with your Elasticsearch instance.
Note: You can change other default configurations by simply uncommenting specific settings in the configuration file and modifying their values.
Step 3: Run the Docker image
Run the Docker image with the Connector Service using the following command:
docker run \ -v ~/connectors-config:/config \ --network "elastic" \ --tty \ --rm \ docker.elastic.co/integrations/elastic-connectors:8.16.0.0 \ /app/bin/elastic-ingest \ -c /config/config.yml
Refer to DOCKER.md
in the elastic/connectors
repo for more details.
Find all available Docker images in the official registry.
We also have a quickstart self-managed option using Docker Compose, so you can spin up all required services at once: Elasticsearch, Kibana, and the connectors service.
Refer to this README in the elastic/connectors
repo for more information.

editThe following sections describe Sync rules for this connector.
Basic sync rules are identical for all connectors and are available by default.

You need to specify the tables used in your custom query in the "tables" field.
For example:
[ { "tables": ["table1", "table2"], "query": "SELECT ... FROM ..." } ]

.
This will happen if the query specifies a table that doesn’t appear in the configuration.
This can also happen if the configuration specifies *
to fetch all tables while the advanced sync rule requests for only a subset of tables.
