OpenSearch is an open-source search and analytics suite which serves as a centralized location to manage logs forwarded from other resources, such as databases and Droplets.

You can update your database engine’s parameters, such as http_max_content_length_bytes and indices_query_bool_max_clause_count.

For a full list of the parameters you can edit, see the control panel or API reference, under the REQUEST BODY SCHEMA section, click config, and then click the opensearch option. To ensure database stability, you can only edit the parameters listed. To change other OpenSearch parameters, contact support.

Update a Database’s Configuration Using the Control Panel

To update a database’s configuration from the control panel, click on the database cluster you want to configure, go to the Settings tab, scroll down to the Advanced Configurations section, and click Edit.

Browse the list or use the search bar to find the configuration you want to edit, then click the pencil icon. Use the text box or dropdown menu to enter your new configuration, then click Update to confirm your changes.

Update a Database’s Configuration Using the CLI

How to Update a Database’s Configuration Using the DigitalOcean CLI

Install doctl, the official DigitalOcean CLI.
Create a personal access token and save it for use with doctl.
Use the token to grant doctl access to your DigitalOcean account.
```
doctl auth init
```

Finally, run doctl databases configuration update. Basic usage looks like this, but you can read the usage docs for more details:

doctl databases configuration update <db-id> [flags]

The following command updates a MySQL database’s time zone:

doctl databases configuration update f81d4fae-7dec-11d0-a765-00a0c91e6bf6 --engine mysql --config-json '{"default_time_zone":"Africa/Maputo"}'

Update a Database’s Configuration Using the API

How to Update a Database’s Configuration Using the DigitalOcean API

Create a personal access token and save it for use with the API.
Send a PATCH request to https://api.digitalocean.com/v2/databases/{database_cluster_uuid}/config.

Using cURL:

curl -X PATCH \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"config": {"sql_mode": "ANSI,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE,STRICT_ALL_TABLES","sql_require_primary_key": true}}' \
  "https://api.digitalocean.com/v2/databases/9cc10173-e9ea-4176-9dbc-a4cee4c4ff30/config"

Python

Using PyDo, the official DigitalOcean API client for Python:

import os
from pydo import Client

client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))

resp = client.databases.patch_config(database_cluster_uuid="a7aba9d")
