it fixes the issue No problems with this approach.
Remember to rebuild index and update stats before making it read only again.

I wish this helpful for you I am going to recommend an approach which to some extent would depend on the answer to the following question:
What is the maximum acceptable time delay from the time when a message is committed to the database to the time the message becomes available for a customer to see it?

seems to work fine In MySQL there are more than one way to achieve this.
The method you choose depends on many variables, such your actual pagination method (whether you just want to have "previous" and "next" buttons, or actually want to provide range from 1...n, where n is total number of matching records divided by your your per page records count); also on database design, planned growth, partitioning and/or sharding, current and predicted database load, possible hard query limits (for example if you have years worth of records, you might require end user to choose a reasonable time range for the query (last month, last 3 months, last year, and so on...), so they don't overload the database with unrestricted and too broad queries, etc.. To paginate:

seems to work fine Most decisions are about trade-offs, and this is no exception. In the usual definition of microservices, each service would have it's own database for the reasons @thiago-custodio mentions. You get complete separation and encapsulation of your service. This, however, puts more burden on the operational aspects of the business, as you now have N databases to administrate. You also have a new "how do all the things talk to each other" problem to solve. This may or may not be an issue for you.
You could get some of the benefits of service separation and encapsulation from sharing a database but, for example, having separate schemas for each service. You still get some level of isolation at the database level, but reduce your operational complexity. Again, trade-offs.

wish of those help You are correct, each microservice should use its own data store that fits best to its needs. There might be a service that want's to store its data in a blob storage, another may store its data in a table storage or DocumentDb or SQL Database.
You probably want to use Database-as-a-Service thus not hosting your own db because you don't have to worry about availabilty, scaling, backups...
