How to optimize bulk inserts in PostgreSQL?
Unlogged tables is a PostgreSQL feature that can be used effectively to optimize bulk inserts. PostgreSQL uses Write-Ahead Logging (WAL). It provides atomicity and durability, by default.
What kind of data is used for Bulk insert?
The term “bulk data” is related to “a lot of data”, so it is natural to use original raw data, with no need to transform it into SQL. Typical raw data files for “bulk insert” are CSV and JSON formats. In ETL applications and ingestion processes, we need to change the data before inserting it.
What are the ACID properties of PostgreSQL database?
PostgreSQL uses Write-Ahead Logging (WAL). It provides atomicity and durability, by default. Atomicity, consistency, isolation, and durability make up the ACID properties. Inserting into an unlogged table means that PostgreSQL does inserts without writing into the transaction log, which itself is an I/O operation.
What’s the fastest way to do a Bulk insert?
One way to speed things up is to explicitly perform multiple inserts or copy’s within a transaction (say 1000). Postgres’s default behavior is to commit after each statement, so by batching the commits, you can avoid some overhead. As the guide in Daniel’s answer says, you may have to disable autocommit for this to work.
