Form-factor of Arduino R3 pin layout on FRDM-K64F

ATael-OracleFeb 23 2015 — edited Feb 25 2015

Hello,

I have just got my FRDM-K64F board and I'd like to add a few sensors to it to test it out. I've read that the board has a form-factor of Arduino™ R3 pin layout and I am not sure what that means when I am buying sensors (i2C, SPI, UART interfaces) for this board. I understand that I can just connect any sensor using a breadboard and cables but I was thinking that maybe this Arduino R3 pin layout is something that makes it easier?

As you probably can see, my HW skills a nothing to brag about....

Many Thanks

Andy

You want to use MySQL Router as the load balancer for the cluster.  If you are running a load balancer to get to the application that is fine but bot for InnoDb Cluster traffic.

Hello,

Putting MySQL Router on a dedicated server (or more) is OK, but I really don't understand the benetifs to put it on cluster nodes !

Maybe your loadbalancer doesn't close connections ? Like that it's difficult to answer. Check the connectio status and variables in MySQL and check the connections in the router.

Regards,

Place Router on the application nodes not on the InnoDB cluster nodes.  See https://dev.mysql.com/doc/mysql-router/8.0/en/

Hello,

I agree with all the answers. I still don't understand this statement:

"You want to use MySQL Router as the load balancer for the cluster."

Is MySQL Router a load balancer by itself? Then does the Router itself have HA capability?

Thanks,

MySQL Router will load balance the queries to innoDB Cluster or ReplciaSet.

In my test environment, I installed multiple mysqlrouter and start them. I'm testing if one of mysqlrouter process stop, can client connection be failed over to another mysqlrouter instance automatically. I tested with Keepalived. So far it wasn't successful. It looks like mysqlrouter is Single-Point-of-Failure.
