Sysbench 0.5 Running the Benchmarks pgenchįirst, initialize the pgbench database. Pgbench (PostgreSQL) ~]# sysbench -version Verify that everything is in ~]# psql -version Also, we need to set the paths to PostgreSQL binaries and libraries:Įxport PGHOST=. export PGHOST=.Įxport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib One way of doing it is by initializing the environment variables in. The last step in getting the environment ready is configuring the PostgreSQL connection parameters. Next, install and configure the benchmark tools, pgbench and sysbench, by following the instructions in the Amazon guide. The client is an on demand r4.8xlarge EC2 instance:.Both the client and the target instances are in the same availability zone.įirst, setup the client and the database instances:.The database does not include a replica. The Enhanced Networking must be enabled for the client instance.On a related note, I had to download the AWS timing patch from this pgsql-hackers submission since it was no longer available at the link mentioned in the guide. The connections are limited to a maximum of 1,000 as the AWS patch for pgbench did not apply cleanly.No changes to the cloud provider default GUC settings.Setting Up the EnvironmentĪ few notes about the constraints related to setting up the environment and running the benchmark, points that were discussed in more detail during Part 1 of this series: As announced in the RDS forum AWS made PostgreSQL 11.1 available on March 13th, which is four months after the community release. It’s worth pausing for a second to quickly review the PostgreSQL versions currently available in the cloud:Īmazon is again a winner, with its RDS offering, by providing the most recent version of PostgreSQL. At the time of this writing the latest PostgreSQL version is 11.2 released about a month ago. In this part, pgbench and sysbench will be running against Amazon RDS for PostgreSQL 11.1. In Part 1 I presented an overview of the available tools, I discussed the reason for using the AWS Benchmark Procedure for Aurora, as well as PostgreSQL versions to be used, and I reviewed Amazon Aurora PostgreSQL 10.6. This is the second part of the multi-series Benchmarking Managed PostgreSQL Cloud Solutions.
