Yesterday, Bhuvanesh published an article about how to verify the difference between allocated diskspace for a tablespace and the the data in it.

I commented with an old post explaining how to get some similar info only using SQL in case you don’t have filesystem access.

And finally, my friend Bill Karwin, commented how this info is not always accurate. Which, of course, I agree with.

This is why, I checked …

The post dbForge Studio for MySQL is a DBTA 2019 Finalist appeared first on blog.

Its not the new term for DBAs. MySQL has an awesome parameter innodb-file-per-tables allows MySQL to create separate files for each tables. This helped a lot to manage the disk space in more efficient way. But when we perform a large batch job for delete or update the data in MySQL tables, you may face this fragmentation issue. Comparing with SQL server, MySQL’s fragmentation is not high. I had a similar situation where my Disk space was consuming 80% and when I check the huge files in OS, one table’s idb file consumed 300GB+. I know it has some wasted blocks(but not actually wasted, MySQL will use this space, it’ll not return this to OS) Then I checked the information schema to find out the data size and its index size. It was 27GB only. Then I realize, we did a batch operation to delete many billions of records in that table.

In my blog series about external contributions to MySQL 8 we have reached version 8.0.18 which was released Monday 14 October 2019. Again the community has contributed to make MySQL better. Thank you.

The contributions to MySQL 8.0.18 includes several patches from Facebook as well as patches from Gillian Gunson, Przemysław Skibiński (Percona), Daniel Black, and Satya Bodapati (also Percona). The contributions are:

• MySQL now provides more control over the use of compression to minimize the number of bytes sent over connections to the server. Previously, a given connection was either uncompressed or used the zlib compression algorithm. Now, it is also possible to use the zstd algorithm (zstd 1.3), and to …

In the process of enhancing MySQL replication with new features for our users, we also improve the internals. A lot of work goes also to modernize the codebase and make it easier to maintain and obviously extend as well.

In MySQL 8.0.18,…

We have been working with PMM for quite a long time, we do most of the performance analysis with PMM for most of our clients. It also provides the flexibility that we have built our own custom dashboard. PMM has many advantages

• Easy to deploy (docker based)
• Flexible
• Customizable
• Query Analytics
• One-stop solution for MySQL,Mongo,ProxySQL & PostgresSQL
• Orchestrator
• Rich and Deep metrics stats

Highly recommended for any production deployments its equivalent to Enterprise-grade monitoring and graphing tool.

Recently we have been working for our client on MySQL Consulting to scale peak sale of the year. Wherein we have deployed PMM to view the performance …

Group Replication enables you to create fault-tolerant systems with redundancy by replicating the system state to a set of servers. Even if some of the servers subsequently fail, as long it is not all or a majority, the system is still available.…
