Installation and Migration experiences at Stanford University | Stanford is running a K8s-cluster on VMs, not using Rancher. They run Kubernetes with Lens | The Kubernetes IDE (k8slens.dev) . They report issues in having Postgres run in Kubernetes. This led to very slow data loading, resulting in 3.000 records having been loaded in 45 minutes! They need to load 9 mio. records; using Apache Airflow (as Jeremy had shown in a demo in one of these sessions). Interactions of Postgres with the modules (which set off SQL commands) and other modules that run in the cluster made Postgres so slow. They solved this by running Postgres on a separate VM. But they want to bring back Postrgres to the cluster, using some kind of clustered and HA Postgres. | ||
TC Pain Points subgroup of SysOps | Tod Olson | The subgroup met on Wednesday but could not re-meet on Thursday, due to overlapping work. Progress was made in defining the concerns about the Release Upgrade procedure. Tod says issues in batch import and data migration still need to be worked out. If the import jobs fail, there is no sufficient information where it exactly failed. Maybe it has succeeded in 49,999 of 50,000 records, but one would not know and have to re-run the import job. This in turn would run into conflicts with optimistic locking in upserts, which have been recently reported (and are already being extensively discussed elsewhere - MODINVSTOR-924Getting issue details... STATUS ). Module logging and behavior in case of failure should follow a common expectation, common accross the modules. Tod will edit the SysOps Pain Points paper, accordingly, and ask for feedback in the SysOps Slack chat. The subgroup is planning to re-meet next Wednesday (June 22nd). |
