So a physical replication slot can be created on the primary server and the location up to where the transactions have been sent to the standby is stored. Now when the standby loses connection, the primary server will keep those WAL files. To further streamline and prepare your data for analysis, you can process and enrich Raw Granular Data using Hevo’s robust & built-in Transformation Layer without writing a single line of code!
Hevo can be a good choice if you’re looking to replicate data from 100+ Data Sources (including 40+ Free Data Sources) like PostgreSQL into Google BigQuery, Amazon Redshift, Snowflake, and many other databases and warehouse systems. Hevo also supports PostgreSQL as a destination including native connectors for various variants of PostgreSQL like Cloud, on-premise, etc. Because just the log file needs to be flushed to the disc to ensure that a transaction is committed, rather than every data file modified by the transaction, using WAL leads to a greatly decreased amount of disc writes. Because the log file is written sequentially, synchronizing the log is substantially less expensive than flushing the data pages. This is especially true for servers that handle a large number of tiny transactions that interact with various areas of the data store.

Furthermore, if the server is executing a large number of minor concurrent transactions, a single “fsync” of the log file may be enough to commit a large number of them. Write-Ahead Log is a record of the changes made to the data. It ensures that when there is a crash in the system or loss of connection, the database can be recovered. When you make changes to the database, WAL files keep building up.
