New Postgres Connection Pooler PgDog Introduced with Session-Level SQL Support
Key points
- PgDog allows session-level SQL without losing connection state.
- PgBouncer can increase throughput with multiple processes and so_reuseport.
- PgDog aims to reduce application code changes.
- PgBouncer faces query cancellation issues.
- PgDog and PgBouncer optimize Postgres connection pooling.
PgDog: A New Approach to Connection Pooling
PgDog is introduced as a new connection pooler for PostgreSQL. It enables use of session-level SQL commands without losing the connection state, unlike existing solutions which often require significant code adaptation in applications. This aims to overcome the limitations of tools like PgBouncer, which introduce leaky abstractions necessitating code changes.
Enhanced Performance of PgBouncer
An enhancement technique for PgBouncer has been discussed, involving deploying multiple processes and utilizing so_reuseport. This allows PgBouncer to better utilize multicore machines by distributing load across CPU cores, effectively increasing throughput. However, it has limitations such as issues with query cancellations across processes.
Why This Matters
Both PgDog and optimized PgBouncer implementations offer improved methods for managing database connections in PostgreSQL. Users looking for scalable and less intrusive solutions might find PgDog appealing, while those dealing with throughput constraints can benefit from the advanced deployment strategies for PgBouncer.
