Percona XtraDB Cluster 8.0 (experimental release) : SST Improvements

Starting with the experimental release of Percona XtraDB Cluster 8.0, we have made changes to the SST process to make the process more robust and easier to use.

  • mysqldump and rsync are no longer supported SST methods.

    Support for mysqldump was deprecated starting with PXC 5.7 and has now been completely removed.

In summary, whenever you read from or write to a file (unless you are using Direct_IO to bypass the functionality), the result is cached in memory, so that subsequent requests can be served from it, instead of the orders of magnitude-slower disk subsystem (it can also be used to cache writes, before flushing them to disk). This is done as far as there is memory that is not being used by any process; whenever there is a shortage of otherwise free memory, the kernel will choose to first evict the page cache …
