- Upcoming Database Migration Will Require Taking BOINC Database Offline Between March 10th-11th - we have been testing the distributed Postgres architecture in our new staging environment. We intend to switch over to our Postgres build of the BOINC server v1.6.1 release next week, between March 10th-11th. The cutover will require a brief pause while we deploy the updated scheduler and feeder to each Postgres worker node, and rollout CDC via Kafka in production to match the staging deployment. With CDC, we will keep the legacy databases in sync with workunit state managed by the Postgres cluster.
- CRUD operations from create_work and validator_assimilator daemons will be pipelined by a journaling process to keep workunit state eventually consistent in the legacy BOINC database, so that the current API layer and business logic will continue to work as usual. What we gain is the IOPS available to the BOINC database will scale to the number of servers we deploy in the Postgres cluster, and batch updates to the database will preserve data locality, completing the horizontally scalable design.
- This should resolve the long-standing validation issues, high disk utilization for the current BOINC database, and enable us to return to strict homogenous redundancy classes for MCM1 workunits, solve the os_name and os_version buffer overflow and trunctation bug, and give us access to the new features implemented in the more recent BOINC releases, such as running containers as applications on the grid.
- We are able to produce and run MCM1 and MAM1 workunits through this system in staging, and will launch ARP1 shortly after we confirm it delivers as expected and described above. We also should then be able to release a larger quantity of workunits than we were previously able to for ARP1 and accelerate the completion of the project.
