Zero Downtime Licensing applies only to Tableau Server, since Tableau Online handles licence key changes behind the scenes without a restart.
Previously you always had to restart Tableau Server so it could recognise newly added licence keys, but as of this release that is no longer needed for most updates.
The one exception is changing allowed data sources for embedded use cases, which still requires a server restart.
The feature lets you decouple upgrade scheduling from hard licence expiry deadlines, so upgrades can be done weeks apart from licence updates.

0:00Hey, it's Tim here. This is a super short

0:01video on a new feature in 2020.1 called

0:04Zero Downtime Licensing.

0:06Essentially this feature allows you to

0:07essentially add a state or add license keys

0:10to your server

0:11without having to restart them. Now there

0:13is a condition for this. Number one, this

0:15is only for

0:16Tableau Server. Tableau Online doesn't need

0:18a restart or any sort of reconfiguration

0:21whenever

0:21you add a license key to it. It's almost

0:23sort of done behind the scenes. But for

0:25Tableau Server,

0:26anytime you add anything in the past, you

0:28've always needed to restart the server so

0:30the server

0:31can recognize the keys. It's just a part of

0:33the process essentially. But as of 2020.1.1

0:36,

0:36essentially anytime you add anything, you

0:38don't need to restart the server. There is

0:41one exception

0:41there. That is the ability of adding

0:44allowed data sources. And this is specific

0:46for embedded use

0:47cases, essentially where you have to

0:49specify certain data sources up front. If

0:52you're changing

0:52those allowed data sources, then you're

0:54going to need to do a restart. You can just

0:56see it here

0:56in the matrix. So I'll include this link in

0:58the description below. Check it out. But if

1:00you're a

1:00server admin, hopefully this is just adding

1:03an additional nine to your uptime stats for

1:05the

1:06upcoming year. And hopefully it'll make

1:07your life a lot easier, especially when it

1:09comes to upgrades.

1:10Because essentially what people tend to do

1:12is they schedule upgrades with their

1:13licenses,

1:14when in fact maybe the upgrades can be done

1:16maybe a couple of weeks apart from when

1:19they're actually

1:19doing their license sort of updates,

1:21because you've got an absolute hard

1:23deadline when the license

1:24expires. So that's pretty much it. There's

1:26not much more to the video. Hopefully

1:28people find that

1:29useful. And yeah, catch me in the next

1:30video. I will be covering more features on

1:32Tableau Server

1:33as of this release. So be sure to check

1:35those out as and when they come in over the

1:37next couple of

1:38weeks. Catch you in the next one.

Rollup

Tableau Server 2021.1 introduces Zero Downtime Licensing, so you can add or update licence keys without restarting the server for most scenarios. This matters because it lets you decouple licence renewals from your upgrade schedule instead of treating them as the same event.

Previously, adding a licence key to Tableau Server always required a restart so the server could recognise it. Tableau Online never had this problem since key changes happen behind the scenes.

The Breakdown

Applies only to Tableau Server 0:00

This feature is specific to Tableau Server. Tableau Online already applies licence key changes behind the scenes without needing a restart, so this is purely a server-side improvement.
No restart needed for most licence changes 0:21

As of this release, adding licence keys to Tableau Server no longer requires a restart, removing a step that was previously mandatory every time keys were updated.
One exception: allowed data sources for embedded use cases 0:41

If you're changing allowed data sources for embedded scenarios, where certain data sources must be specified up front, you still need to restart the server. Check the referenced matrix if you're unsure whether a specific change requires a restart.
Separate your upgrade and licensing schedules 1:01

Admins often bundle server upgrades with licence renewals because the licence expiry creates a hard deadline. With this feature you can now schedule upgrades independently, potentially weeks apart from licence updates, since renewing a licence no longer forces downtime.

Worth Knowing

The allowed data sources exception only applies to embedded use cases where data sources are specified upfront — general licence key additions aren't affected.

Use It When

Reach for this awareness when planning Tableau Server maintenance windows or licence renewals, so you stop tying upgrade timing to licence expiry deadlines unnecessarily.
