QUESTION

Mysql per thread memory, variables that lead to thread memory usage?

Asked 2021-Jan-20 at 19:11

We recently upgraded from mysql 5.6 to mysql 8.0 on a few servers, one of the servers was fine, and has had no problems, but it has significantly less load than one of our other servers which has been running out of memory.

Our server launches, then grabs 300 connections, and keeps them open with a C3P0 pool to the mysql server.

We were running these servers on AWS on MySQL 5.6 with the same overridden parameters on 8GB of RAM, when we upgraded to MySQL 8.0.21 we started running out of RAM in about 1 day. We grew the server to 32Gb but didn't change the parameters. It's gone over 15 GB used and still going up.

We're pretty sure it's related to the per connection thread memory, but not sure why. From looking at MySQL tuner it looks like the variables that control per thread memory are:

You're calculating the per-thread memory usage wrong. Those variables (and tmp_table_size which you didn't include) are not all used at the same time. Don't add them up. And even if you were to add them up, at least two might be allocated multiple times for a single query, so you can't just sum them anyway.

Basically, the memory usage calculated by MySQLTuner is totally misleading, and you shouldn't believe it. I have written about this before: What does "MySQL's maximum memory usage is dangerously high" mean by mysqltuner?

If you want to understand actual memory usage, use the PERFORMANCE_SCHEMA, or the slightly easier to read views on it, in the SYS schema.

The documentation for PS or SYS is pretty dense, so instead I'd look for better examples in blogs like this one:

To trigger the replica being recreated you will need to have a ForceNew parameter on the replica resource change when the non replica changes.

With RDS there is a resource_id attribute that isn't normally surfaced in places people care about (you don't specify it, you don't use it to connect to it and it's not shown in the RDS console) but is different for each database instance (compared to the normal identifier which is specified).

This then brings us to the other part which is that that attribute needs to be in a ForceNew parameter on the replica resource. The obvious choices here are either the identifier or identifier_prefix parameters. The biggest impact here is that these are also used to identify the database instance from others but also used as part of the DNS address to connect to the database in the form of ${identifier}.${random_hash_of_account_and_region}.${region}.rds.amazonaws.com. So if you're needing to connect to the instance then you'll either need to have the client discover the replica address as it will now contain the randomly generated resource_id of the non replica instance or you'll need to have Terraform create a DNS record that either CNAMEs or aliases the RDS address.

So in your case you might want something like this:

QUESTION

Terraform resource recreation dynamic AWS RDS instance counts

Asked 2019-Jan-28 at 08:14

I have a question relating to AWS RDS cluster and instance creation.

Environment

We recently experimented with:

Terraform v0.11.11 provider.aws v1.41.0

Background

Creating some AWS RDS databases. Our mission was that in some environment (e.g. staging) we may run fewer instances than in others (e.g. production.). With this in mind and not wanting to have totally different terraform files per environment we instead decided to specify the database resources just once and use a variable for the number of instances which is set in our staging.tf and production.tf files respectively for the number of instances.

Potentially one more "quirk" of our setup, is that the VPC in which the subnets exist is not defined in terraform, the VPC already existed via manual creation in the AWS console, so this is provided as a data provider and the subnets for the RDS are specific in terraform - but again this is dynamic in the sense that in some environments we might have 3 subnets (1 in each AZ), whereas in others perhaps we have only 2 subnets. Again to achieve this we used iteration as shown below:

ANSWER

Answered 2019-Jan-28 at 08:14

Turns out that simply by just removing the explicit availability zones definitions from the aws_rds_cluster and aws_rds_cluster_instance then this issue goes away and everything so far appears to work as expected.

Install slowquery

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
