MySQL RDS Performance Insight got stuck

jp flag

We are using AWS MySQL RDS. Quite recently, we are saw MySQL RDS Performance Insight got stuck with

SET `@slave_uuid` = ?

Like the following image

Top SQL from RDS Performance Insights

The second one that follows the above is

Use `db_name`

As I check from the cloud watch monitoring. All the CPU/IOPS are pretty normal.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
