I've got a question about Galera cluster + MySQL/MariaDB and RAM.
Basically, our MySQL cluster needs to run in-memory.
- We have 3 TB of data;
- We don't have 100,000$ for RAM :)
- We need High Availability.
In this case, is Galera a good solution? Will it run with 3 nodes (each with 128GB RAM and SSD's)?
