A block is the basic unit of database management, with a default size of 8 KB. Data can be distributed in replication, round-robin, or hash mode. You can specify the distribution mode during table creation. Figure 2 Logical database architecture Physical Architecture of a Cluster GaussDB(DW...
PostgreSQL, also known as Postgres, is an open source relational database management system (DBMS) renowned for its flexibility, scalability, and extensive feature set. With a rich history dating back to its inception at the University of California Berkeley in 1986, PostgreSQL has evolved into a...
PostgreSQL 15 will also positively surprise those using logical replication. It will be possible to filter by rows and columns, and to specify publishing all tables in a schema instead of in a database (as was the case until now). It is worth mentioning that in the new version of PostgreS...
What is PostgreSQL as a Service? PostgreSQL as a Service (PGaaS) is a specific form of Database as a Service (DBaaS) that enables users to easily create, manage, and use Postgres databases in the cloud. Various cloud service providers offer PGaaS options, including AWS with RDS ...
The replication controller is responsible for ensuring that the number of pods deployed in the cluster matches the number of pods in its configuration. If a pod or underlying host fails, the controller will start new pods to compensate. If the number of replicas in a controller’s configuration...
With PostgreSQL, when using physical replication, all the replicas will be in read-only mode. Logical replication has the capability to allow the writes, but it’s not recommended to have writes in both nodes at the same time without a strong conflict-resolution solution. You can, ...
In contrast, logical replication operates on data’s replication identity, like a primary key, rather than its physical location. While PostgreSQL lacks native multi-master replication, third-party tools provide solutions for this. SQL Server Replication SQL Server provides three types of replication:...
During preview, you can interact with clusters in us-east-1 – US East (N. Virginia) and us-east-2 – US East (Ohio). Compatibility with PostgreSQL databases The distributed database layer (compute) in Aurora DSQL is based on a current major version of PostgreSQL. You can connect to ...
Pay attention to the below-mentioned text to understand CRDs in a better way. etcd is the storage destination for CRDs Core resources and CRDs are kept together It’s possible to use features like replication & lifecycle management No logical information or particular behavior trait is linked ...
Logical replication of distributed tables to PostgreSQL tables In PostgreSQL, logical decoding forms the basis of logical replication, which allows you to replicate changes from one PostgreSQL server to another. It is now also possible to set up logical replication from a distributed table to a regu...
