Hey everyone, I’m hitting a wall with my MySQL/MariaDB setup. The database has grown so big that a single server just can’t keep up anymore. I’ve already tried beefing up the CPU and RAM, and even set up regular replication, but it’s not cutting it.
I’m wondering what you guys do when you face this problem. Do you use something like ProxySQL to split the traffic between different servers? Or maybe you’ve got some other tricks up your sleeve?
Also, I’ve heard about TiDB as a possible solution. Has anyone here made the switch? If so, how did you make sure your app’s SQL was fully compatible? Any tips or gotchas I should watch out for?
I’d really appreciate any advice or experiences you can share. Thanks in advance!
Having faced similar challenges, I can attest that vertical scaling has its limits. In our case, we found success with a multi-pronged approach. We implemented database partitioning, which allowed us to distribute data across multiple servers based on logical divisions. This significantly improved query performance and made management easier.
We also leveraged caching extensively, using Redis to offload frequently accessed data from MySQL. This reduced the load on our database servers and improved response times dramatically. For analytics and reporting, we set up a separate data warehouse, which allowed us to run complex queries without impacting our main operational database.
Regarding TiDB, while it’s an intriguing option, we found the learning curve and potential compatibility issues outweighed the benefits for our use case. Instead, we focused on optimizing our existing MySQL setup, which proved more cost-effective and less disruptive in the short term.
hey mate, i feel ur pain. we hit that wall too. ended up goin with galera cluster - it’s like a beefed up replication setup. syncs writes across multiple nodes so u can scale out. bit tricky to set up but works like a charm now. might be worth checkin out if ur sql is mostly innodb. good luck!
I’ve been in your shoes, and it’s a tricky situation. When our MySQL setup started buckling under load, we explored a few options before settling on a solution.
We initially looked into sharding, which helped distribute the load across multiple servers. It required some application changes, but it significantly improved performance for our write-heavy workload.
Another approach we considered was implementing a read/write split using ProxySQL. This allowed us to offload read queries to multiple replicas while directing writes to the primary server. It was less invasive than sharding and gave us a good performance boost.
Ultimately, we ended up adopting a combination of both strategies. We sharded our largest tables and used ProxySQL for read/write splitting on the remaining ones. It took some time to implement, but the scalability gains were worth it.
As for TiDB, I’ve heard good things but haven’t personally used it. If you go that route, thorough testing of your SQL queries is crucial. Maybe start with a small, non-critical part of your application to test the waters.
