Large Amount of Object Data within the `analyticsmessage` table.

Issue

We're experiencing slow database restore times due to excessive large object data, primarily within the `analyticsmessage` table.
When planning an upgrade, we've found a table with millions of objects, slowing down the process.

The `analyticsmessage` table stores audit data related to users, groups, organizations, and other entities that are synchronized with the Analytics Cloud. Although this data is usually deleted after being sent to the Analytics Cloud, a high volume of entries can sometimes cause a backlog.
If this table is causing delays in your database backups before upgrading, our team has determined that it is safe to clean up the `analyticsmessage` table. The improved syncing method, which now uses batching, no longer relies on this table. However, to prevent any potential data loss, please reconfigure your Analytics Cloud settings to resync contacts after upgrading to 2023.Q4+.

Before making any changes to your database, it's crucial to back up your data. Having a recent backup ensures that you can restore your database to its original state if something goes wrong, preventing potential data loss or system downtime.
