In order to replicate changes to your PostgreSQL table into the data lake, you first need to enable logical replication. If you are unsure whether or not logical replication has been configured, you can run the
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....
The replication uses the table membership in replication sets with the node replication sets configuration to determine the actions to replicate and the node to replicate them to. The decision is done using the union of all the memberships and replication set options. Suppose that a table is a ...
The main difference from table replication is that DDL replication doesn't replicate the result of the DDL. Instead, it replicates the statement. This works very well in most cases, although it introduces the requirement that the DDL must execute similarly on all nodes. A more subtle point is...
To quickly try out pg_replicate, you can run the stdout example, which will replicate the data to standard output. First, create a publication in Postgres which includes the tables you want to replicate: create publication my_publication for table table1, table2; Then run the stdout example...
On the Production instance, create a publication for the tables you wish to replicate. For instance: SQL CREATEPUBLICATION my_pubFORTABLEyour_table_name; On the Development instance, set up a subscription that links to the publication you created on the Production instance. For example: ...
type. For example, you can replicate from a column of typeintegerto a column of typebigint. The target table can also have additional columns not provided by the published table. Any such columns will be filled with the default value as specified in the definition of the target table. ...
In the future, we would also like to support a “seeds” section that outputsINSERTstatements for sample data created by the language model. Unfortunately we can't simply concatenate these queries together like we do with migrations, since table and column structure can change over time and brea...
As in the above-shown figure, the four steps to replicate Postgres to Snowflake using custom code (Method 2) are as follows: 1. Extract Data from Postgres The “COPY TO” command is the most popular and efficient method for extracting data from a Postgres table to a file. We can also...
Many people use streaming replication to make their systems replicate more data to a slave as soon as possible. In addition to that, file-based replication is often utilized to make sure that there is an extra layer of security. Basically, both mechanisms use the same techniques; just the ...
