Lastly, for mysqldump, we can say that it has the most predictable behavior and has similar execution times with different runs. One possibility is because mysqlpump streams the data to a single file. I tested mysqlpump with zstd compression, but the results were the same, hence the reason I didn’t add it to the chart. Both are logical backup methods and works in the same way. Next, mysqlpump is more efficient than mydumper with gzip, but only by a small margin. The main advantage of XtraBackup is its flexibility, providing PITR and encryption for example. XtraBackup got third place with a few seconds of difference from MySQL shell. Like mydumper, it uses multiple files to store the data and has a good compression ratio. The mydumper tool cut the execution time by 50% when using zstd instead of gzip, so the compression method makes a big difference when using mydumper.įor the util.dumpInstance utility, one advantage is that the tool stores data in both binary and text format and uses zstd compression by default. Parallel methods have similar performance throughput. $ time xtrabackup - backup - parallel= 16 - compress - compress- threads= 16 - datadir=/ mysql_data/ - target- dir=/ backup/ In a server with more CPUs, the potential parallelism increases, giving even more advantage to the tools that can benefit from multiple threads.mysqldump is the classic old-school style to perform dumps and is the slowest of the four tools.mysqlpump is the 4th fastest followed closer by mydumper when using gzip.When mydumper is using gzip, MySQL Shell is the fastest backup option.This option was added not long ago ( MyDumper 0.11.3). When using zstd compression, mydumper really shines in terms of performance.The exception for this is mysqldump, which does not have a parallel option and only runs in a single-threaded mode. We can observe the results in the chart below:Īnd if we analyze the chart only for the multi-threaded options:Īs we can see, for each software, I’ve run each command three times in order to experiment using 16, 32, and 64 threads. The MySQL version was 8.0.26 and configured with 89Gb of buffer pool, 20Gb of redo log, and a sample database of 177 GB (more details below). The benchmark was run on an m5dn.8xlarge instance, with 128GB RAM, 32 vCPU, and 2xNVMe disks of 600GB (one for backup and the other one for MySQL data). To start, let’s see the results of the test. All these available options are open source and free to use for the entire community. Siminnovations.In this blog post, we will compare the performance of performing a backup from a MySQL database using mysqldump, MySQL Shell feature called Instance Dump, mysqlpump, mydumper, and Percona XtraBackup.
