## July 2023

- <Expandable alt_header='Faster runs and unlimited job concurrency for Enterprise account'>

    We’ve introduced significant improvements to the dbt Cloud Scheduler, offering improved performance, durability, and scalability. 

    Read more on how you can experience faster run start execution and how enterprise users can now run as many jobs concurrently as they want to.

    ## Faster run starts

    The Scheduler takes care of preparing each dbt Cloud job to run in your cloud data platform. This [prep](/docs/deploy/job-scheduler#scheduler-queue) involves readying a Kubernetes pod with the right version of dbt installed, setting environment variables, loading data platform credentials, and git provider authorization, amongst other environment-setting tasks. Only after the environment is set up, can dbt execution begin. We display this time to the user in dbt Cloud as “prep time”.

    For all its strengths, Kubernetes has challenges, especially with pod management impacting run execution time. We’ve rebuilt our scheduler by ensuring faster job execution with a ready pool of pods to execute customers’ jobs. This means you won't experience long prep times at the top of the hour, and we’re determined to keep runs starting near instantaneously. Don’t just take our word, review the data yourself.

    <Lightbox src="/img/prep-start.jpg" width="85%" title="Job prep time data has seen a 75% speed improvement from Jan 2023 to July 2023. Prep time took 106 secs in Jan and now takes 27 secs as of July."/>

    Jobs scheduled at the top of the hour used to take over 106 seconds to prepare because of the volume of runs the scheduler has to process. Now, even with increased runs, we have reduced prep time to 27 secs (at a maximum) &mdash; a 75% speed improvement for runs at peak traffic times!

    ## Unlimited job concurrency for Enterprise accounts

    Our enhanced scheduler offers more durability and empowers users to run jobs effortlessly. 

    This means Enterprise, multi-tenant accounts can now enjoy the advantages of unlimited job concurrency. Previously limited to a fixed number of run slots, Enterprise accounts now have the freedom to operate without constraints. Single-tenant support will be coming soon.

    Something to note, each running job occupies a run slot for its duration, and if all slots are occupied, jobs will queue accordingly.

    For more feature details, refer to the [<Constant name="dbt" /> pricing page](https://www.getdbt.com/pricing/).

    Note, Team accounts created after July 2023 benefit from unlimited job concurrency:
    - Legacy Team accounts have a fixed number of run slots.
    - Both Team and Developer plans are limited to one project each. For larger-scale needs, our [Enterprise plan](https://www.getdbt.com/pricing/) offers features such as audit logging, unlimited job concurrency and projects, and more.
