Database cluster, how to change max_allowed_packet and max_execution_time?

I have a local MySQL dump that I want to migrate to my database cluster. Since the local MySQL is not available on the network I cant use the normal Migrate database functionality. Instead I want to import it as a dump/backup. However, I am encountering an issue where the query takes longer than 30 seconds or the packet is larger than 16 MB, causing the error Lost connection to MySQL server during query. This is a common problem for larger queries, and the usual solution is to increase the values of the max_allowed_packet and max_execution_time fields. I attempted to do this through the CLI, but I was informed that I need superadmin rights to make these changes. I also cannot find any settings on the dashboard that would resolve this issue.

How do you solve this problem here on DigitalOcean?

Hi there,

For the Managed Database clusters, you can’t directly make the changes, but instead, you would need to use the DigitalOcean API. You can find the documentation on how to make such config changes to your managed clusters here:

Your request will look something like this:

curl -X PATCH \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"config": {"max_allowed_packet": "67108864","sql_require_primary_key": true}}' \

The max_execution_time is not configurable as far as I can see, but you can try also increasing the connect_timeout instead.

Let me know how it goes!
