Create a publication for Upsolver to use: Once logical replication is enabled for your PostgreSQL database, you will need to create a publication that contains the tables you wish to replicate. You can create a publication for all tables by executing the following command: CREATE PUBLICATION up...
And when you have many tables, it’s hard to keep track of it all. Luckily, Postgres provides a lot of information that we can use to better understand its internals. For example, we can look at a table's n_dead_tup value to understand the current number of dead tuples, and relate...
You should include all tables you want to replicate as part of the publication: CREATE PUBLICATION airbyte_publication FOR TABLE <tbl1, tbl2, tbl3>;` The publication name is customizable. Refer to the Postgres docs if you need to add or remove tables from your publication in the future....
Row-based sharding Transparently shard Postgres tables across multiple nodes to give your application more memory, compute, and disk. Which gives you parallelism, high performance, and a way to scale. Plus, you can now shard Postgres on a single Citus node, too. ...
Your Postgres commands in one place. Learn how to use psql to list and create Postgres databases, show your tables, enter your Postgres terminal, and more.
It’s clear that there is almost no difference between the estimated and actual row counts. It’s important to keep the statistics as accurate as possible, because the planner should choose optimal access methods and join tables order. A failure to do so will result in bad plans and poor ...
Once all transactions which require a row version are complete, those row versions can be removed. This can be done by theVACUUMcommand. Now,VACUUMcan be run manually but that requires you to monitor and make decisions about various things like: when to run vacuum, which ...
Good for multi-tenant apps & microservices. On the other hand, row-based sharding allows you to more densely pack your tenants on nodes—plus cross-tenant queries are supported. Best for real-time analytics, time series, & IOT. A single application can use one set of tables when sharding ...
