Release schedule
We are continually improving Materialize with new features and bug fixes. We periodically release these improvements to your Materialize account. This page describes the changes in each release and the process by which they are deployed.
Schedule
Materialize upgrades all regions to the latest release each week according to the following schedule:
| Region | Day of week | Time |
|---|---|---|
| aws/eu-west-1 | Wednesday | 2100-2300 Europe/Dublin |
| aws/us-east-1 | Thursday | 0500-0700 America/New_York |
| aws/us-west-2 | Thursday | 0500-0700 America/New_York |
Upgrade windows were chosen to be outside of business hours in the most representative time zone for the region.
Materialize may occasionally deploy unscheduled releases to fix urgent bugs as well.
You can find details about upcoming and current maintenance on the status page. You can also use the status page API to programmatically access this information.
When your region is upgraded, you’ll experience just a few minutes of downtime. After the initial downtime, the new version of Materialize will begin rehydrating your indexes and materialized views. This takes time proportional to data volume and query complexity. Indexes and materialized views with large amounts of data will take longer to rehydrate than indexes and materialized views with small amounts of data. Similarly, indexes and materialized views for complex queries will take longer to rehydrate than indexes and materialized views for simple queries.
