MemCP can run on any hardware that is supported by the go compiler.
To find the right hardware dimensions, you need to consider the following:
- The process itself needs at least 8 MiB of RAM
- The size of a 5 GiB MySQL database fits into ~1 GiB of RAM
- To have a decent working set, take the RAM requirements x3, so a 5 GiB MySQL database should run on 3 GiB RAM
- MemCP needs at least 1 CPU core, more is better ;)
Running on Big SMP Machines
MemCP runs best on machiens that have a lot of RAM and CPU cores.
We tested on:
- AMD Ryzen (in various forms)
- HPE Superfome Flex (https://www.hpe.com/us/en/servers/superdome.html)
Running on Raspberry Pi
These are our recommendations to run MemCP on Raspberry Pi:
- Avoid
ENGINE=safe. To have a long life for your flash drive, you should chooseENGINE=sloppy. (ENGINE=loggingwould be a compromise betweensafeandsloppy) - for more information see Persistency and Performance Guarantees - Raspberry Pis have very limited RAM. In most cases, the RAM is sufficient though since most databases only take a few megabytes of RAM. For bigger data, you should wait for MMaped shards, see also: Current Status and open issues
