PIGSTY

Scalable Service

Elastic Performance

Ever-flowing like water, soft yet resilient, converging streams to adapt to endless change!


Great Performance: Hardware Fully Harnessed

Highlights amazing scalability and top-tier hardware performance.
Maximizing the potential of modern hardware with optimized configurations.

  • Single-node query rate reaches 2 million rows/second
  • Single-node write rate can reach 1 million rows/second
  • Default table size limit: 32TB (2^32 x 8KiB Page)

R/W Separation: Unlimited Read Scaling

Offers unlimited replicas through cascading replication with auto traffic routing.
Scale read workloads horizontally without impacting write performance.

  • Read-only Service: Route to read-only replicas with primary as backup
  • Offline Service: Route to special analytics instance with replicas as backup
  • Production Case: One primary with 34+ replicas through cascading bridges

Connection Pooling: High Concurrency

Built-in PGBouncer connection pool, ready out of the box and syncing with postgres.
Handle thousands of concurrent connections efficiently with resource optimization.

  • Xact pooling converts 20000+ client connections to several active server connections
  • Enabled by default, automatically syncing db/user with postgres
  • Deploy multiple pgbouncer instances to circumvent bottlenecks

Load Balancing: Traffic Control

Monitor and schedule request traffic in real-time with HAProxy console.
Intelligent traffic distribution with health checks and failover capabilities.

  • Stateless HAProxy can be scaled at will or deployed on dedicated servers
  • Weights can be adjusted via CLI, draining or warming up instances gracefully
  • Password-protected HAProxy GUI exposed uniformly through Nginx

Horizontal Scaling: Distributive Extension

Citus extension with multi-write and multi-tenant capabilities.
Scale beyond single-node limitations with distributed PostgreSQL.

  • Accelerate real-time OLAP analytics using multi-node parallel processing
  • Shard by row key or schema, supporting multi-tenant scenarios
  • Online partition rebalancing, adjusting throughput capacity

Storage Expansion: Transparent Compression

Achieve 10:1 or even higher compression ratios with colunmar and other exts
R/W data in S3 with FDW, hot/cold separation and unlimited capacity expansion

  • Use timescaledb, pg_mooncake, pg_duckdb for columnar compression
  • Use duckdb_fdw, pg_parquet, pg_analytics to read/write object storage tables
  • Expand or contract storage with S/H RAID, ZFS, and PG tablespaces

Mass Deployment: Large clusters made easy

Designed for extreme scale - flexible for 25K vCPU clusters or 1c1m node
No limit on nodes per deployment - soft constrained only by monitoring capacity

  • Batch Ops at scale through Ansible, saying goodbye to console ClickOps
  • Largest production deployment record: 25,000 vCPU, 3,000+ instances
  • Scale monitoring system with optional Distributed VictoriaMetrics

Elasticity: Cloud-like Elasticity

Supports cloud EC2 deployment, fully leveraging the elastic advantages of cloud
Flexible multi-cloud strategies - enjoy RDS elasticity with EC2/EBS prices

  • Pigsty only needs cloud servers, works the same across any cloud provider
  • Seamless switching between public, private, hybrid, and multi-cloud
  • Scale compute and storage as needed
