HN discussionThere's a lot of ways to approach the common problems found when running multi-master / active-active PostgreSQL. (A complete guide on this, specifically using PostgreSQL in general , was written by one of our solutions engineers, Shaun Thomas: https://www.pgedge.com/blog/living-on-the-edge ) Could you elaborate on what problems you experienced?

HN discussionJust a guess, but some of the undocumented edge cases you saw might be explored in this blog from one of our software engineers, Shaun Thomas. It's all about conflict resolution & avoidance in PostgreSQL, in general: https://www.pgedge.com/blog/living-on-the-edge If understanding how conflicts are handled in pgEdge is helpful, here's a link to the docs on the subject: https://docs.pgedge.com/spock_ext/conflicts And…

HN discussionThe official FAQ has a good amount of info on how conflict resolution is handled ( https://www.pgedge.com/resources/faq )! Relevant excerpt: "pgEdge offers eventual consistency between nodes using a configurable policy (e.g. last-writer-wins) for conflict resolution, along with conflict-free delta apply columns (i.e. CRDTs) for running sum fields. This allows for independent, concurrent and eventually consistent upd…

HN discussionThanks for pointing out the lack of info on conflict resolution in the README! It's been reported and we'll look at getting that updated ASAP. In the meantime, you can find a lot of information in the official FAQ on how conflict resolution is handled ( https://www.pgedge.com/resources/faq ), but at-a-glance, "pgEdge offers eventual consistency between nodes using a configurable policy (e.g. last-writer-wins) for co…

HN discussionWe're a little different in that we're not just 100% open-source, but also 100% compatible with community PostgreSQL. see https://pgscorecard.com for comparisons between pgEdge and YugabyteDB, CockroachDB on that front.

HN discussionpgEdge came about from a pglogical foundation, actually! from one of our blogs: > pgEdge emerged in late 2024 as a serverless distributed Postgres managed cloud service, delivering low latency and high availability in three minutes or less. The pgEdge Platform (for on-premises distributed PostgreSQL) as well as pgEdge Cloud (for deploying in the cloud) was largely inspired by the original capabilities of the pgLogic…

HN discussionInteresting read, but I find it very lacking. PGSQL memory consists of lots of parts; shared_buffers, work_mem, maintenance_work_men, OS Cache size, etc. For those who are interested in a deeper Postgresql tuning tutorial, I suggest this[1] as it highlights a number of important tuning options - specifically for PGSQL 17. Once your DB has been running for a while, run the postgresql-tuner app[2] to see if you have c…

HN discussionWe use logical replication and a pause / swap in pgbouncer for ~5s of paused (but not failed) writes. This is for DBs that are ~1-1.5TB but doesnt have a huge amount of churn/qps Effectively what is described here https://www.pgedge.com/blog/always-online-or-bust-zero-downt...
