MySQL is a complex system that requires many tools to repair, diagnose, and optimize it. Even though backing up MySQL is a widely embraced technique by renowned applications like Facebook, Twitter, Flickr, among others, MySQL is no longer the only big fish in a small pond of database solutions.
MySQL, which is now owned by Oracle that has not dramatically changed the direction of operation for MySQL since acquisition, does not come devoid of its faults, some of which can be your undoing by wasting your time. As a fact, most business owners and technicians do not realize they have a problem with database backups until they need to restore the data and find it’s not there or not in the form that they were expecting.
Even with the high reliability and utility from MySQL devotees, there are a couple of hitches that a high-speed work environment handling a massive workload. Although the databases can be managed, efficiency is in question especially as pertains time wastage.
Trying to wrap your head around it? Read on to find 5 significant reasons which has challenged most MySQL users and can definitely waste your time like has other people:
Replication Problems
MySQL replication is a flexible and reliable data transfer, retrieval and/or data recovery process that allows you to effortlessly maintain multiple copies of a MySQL data by having them automatically copied from a master to a slave setup database.
Every so often, automatic MySQL servers run into replication conflicts, particularly during a manual fail-over when multi-master setups are involved. The root causes of MySQL replication conflict obviously vary, especially for slave setups that are not in read-only mode
The various replication problems cause lags, and the replication lags can further complicate applications logic, simply because they tend to disrupt the data consistency between the slave and the master setups.
Space and Capacity Limitations
For a highly active business, you are likely to have a high dimension of user sessions running simultaneously and, consequently, you might a high connection churn, which may be exhaustive on many of your valuable server resources.
The more many of your customers carry out numerous complete transactions on your website or application, the more likely it is for your MySQL database to experience some delays, which not only decreases functionality effectiveness, but also wastes a lot of time that would otherwise be used to perform other tasks, worse, cause you a lot of downtime.
If your MySQL database does not have the ability to handle multiple transactions without many hitches, you are likely to encounter scaling problems as well as space limitations. Moreover, if the applications in question are not aware that the scaled reads are not synchronized with the write master, the capacity limitations may significantly slow down the load time and speed of your site of application, which will result in unsold inventories, need for refunds as well as negative social media exposure because of unhappy customers.
Complexity of Use
For a data backup solution that can handle a large amount of workload for websites and applications, there are unseen complexities that are only evident with time, as the users employ the different backup services from the MySQL servers is required.
A major challenge with MySQL backup method is the need for reinforcement from complementary tools. MySQL is a complex system that requires many tools to repair, diagnose, and optimize it. Without the help of expert developers and high-quality open source tools to help with the complexity, performance, and health of MySQL systems, managing MySQL can be a difficult event for the successful running of your website or application.
Data Drift
Data is often thought to be constant and immutable. The transformation and normalization of data is a big problem for any business that wants to improve in productivity and profitability.
Data drift is a natural consequence of the diversity of big data sources, wherein slave data becomes out of sync with the master, and is often caused by writing data to a slave or executing certain nondeterministic queries on the master. The operation and maintenance of the MySQL systems can often cause unpredictable mutations of data characteristics.
Like any other data backup tools, MySQL tools can tend to cause data drifts, specifically on row based replications, or worse still, the data differences may go unnoticed until they become crippling which are a great source of inconvenience.
Slow Executions of Queries
As a fact, nothing frustrates a user like slow MySQL performance. If you have not optimized your MySQL, slowly executing queries might be blocking other queries from executing effectively, which creates a ripple effect of slow response times.
This often means that there is need to analyze your query logs frequently, depending on the volatility of the environment. Even though MySQL distributions include the query log analyzer, the tool is outdated, poorly documented, and untested. If you have never performed query log analysis, you might consider starting it off because slow executed queries are yet to catch up with you.
In addition to the slow executing queries, MySQL has a slow MySQLdump, which ships with MySQL distributions. Unfortunately, it is single-threaded and this causes it to be too slow for data-intensive jobs.
Without proper intervention with modern tools like mydumper which uses multiple threads making it 10 times as faster, relying on MySQLdump alone can take up a lot of your time sorting through your MySQL distributions, yet professional data recovery costs hundreds of dollars per hour, and you always get a bill even if the data isn’t recoverable.
MySQL is among the many data backup solutions sort after by people, being up against its own, Oracle-free. Ideally, MySQL is a necessary backup solution for your business’ website or application especially for it being a renowned solution for many, but would require specific expertise to keep up with the backup demands. For this reason, remember that the easiest way to leverage the powerful features of MySQL without making any significant modifications at the application level or writing a single line of code, is to utilize complementary tools like database load balancing software.
