OrioleDB

Next-generation OLTP engine for PostgreSQL

OrioleDB is a PostgreSQL storage engine extension. It claims to provide 4x OLTP performance and to eliminate xid wraparound and table bloat issues. It also claims to provide cloud-native storage, with data stored in S3.

Pigsty ships OrioleDB as a patched PostgreSQL kernel plus the OrioleDB extension.

You can run OrioleDB as an RDS with Pigsty. Current packages support PostgreSQL 16, 17, and 18 on supported Linux platforms. Set pg_mode to oriole to use the /usr/oriole-$v installation path. The orioledb package alias resolves to versioned kernel packages, such as orioledb-16, orioledb-17, and orioledb-18. The current Pigsty package line is OrioleDB 1.8 beta16.

Quick Start

Follow Pigsty’s standard installation process using the oriole configuration template.

curl -fsSL https://repo.pigsty.io/get | bash; cd ~/pigsty;
./configure -c oriole    # Use OrioleDB configuration template
./deploy.yml             # Install Pigsty with OrioleDB

For production deployment, change the password parameters in pigsty.yml before you run the install playbook.

Configuration

pg-meta:
  hosts:
    10.10.10.10: { pg_seq: 1, pg_role: primary }
  vars:
    pg_cluster: pg-meta
    pg_users:
      - {name: dbuser_meta ,password: DBUser.Meta   ,pgbouncer: true ,roles: [dbrole_admin]    ,comment: pigsty admin user }
      - {name: dbuser_view ,password: DBUser.Viewer ,pgbouncer: true ,roles: [dbrole_readonly] ,comment: read-only viewer for meta database }
    pg_databases:
      - {name: meta ,baseline: cmdb.sql ,comment: pigsty meta database ,schemas: [pigsty], extensions: [orioledb]}
    pg_hba_rules:
      - {user: dbuser_view , db: all ,addr: infra ,auth: pwd ,title: 'allow grafana dashboard access cmdb from infra nodes'}
    pg_crontab: [ '00 01 * * * /pg/bin/pg-backup full' ] # Full backup at 1 AM daily

    # OrioleDB specific settings
    pg_mode: oriole                                         # oriole compatibility mode
    pg_version: 18                                          # OrioleDB supports PG 16, 17, and 18
    pg_packages: [ orioledb, pgsql-common ]                 # Install OrioleDB kernel
    pg_libs: 'orioledb, pg_stat_statements, auto_explain'   # Load OrioleDB extension

Usage

To use OrioleDB, install the orioledb package alias. Pigsty uses pg_version to select the PG16, PG17, or PG18 OrioleDB kernel package.

Initialize TPC-B-like tables with pgbench using 100 warehouses:

pgbench -is 100 meta
pgbench -nv -P1 -c10 -S -T1000 meta
pgbench -nv -P1 -c50 -S -T1000 meta
pgbench -nv -P1 -c10    -T1000 meta
pgbench -nv -P1 -c50    -T1000 meta

Next, rebuild these tables with the orioledb storage engine and compare performance:

-- Create OrioleDB tables
CREATE TABLE pgbench_accounts_o (LIKE pgbench_accounts INCLUDING ALL) USING orioledb;
CREATE TABLE pgbench_branches_o (LIKE pgbench_branches INCLUDING ALL) USING orioledb;
CREATE TABLE pgbench_history_o (LIKE pgbench_history INCLUDING ALL) USING orioledb;
CREATE TABLE pgbench_tellers_o (LIKE pgbench_tellers INCLUDING ALL) USING orioledb;

-- Copy data from regular tables to OrioleDB tables
INSERT INTO pgbench_accounts_o SELECT * FROM pgbench_accounts;
INSERT INTO pgbench_branches_o SELECT * FROM pgbench_branches;
INSERT INTO pgbench_history_o SELECT  * FROM pgbench_history;
INSERT INTO pgbench_tellers_o SELECT * FROM pgbench_tellers;

-- Drop original tables and rename OrioleDB tables
DROP TABLE pgbench_accounts, pgbench_branches, pgbench_history, pgbench_tellers;
ALTER TABLE pgbench_accounts_o RENAME TO pgbench_accounts;
ALTER TABLE pgbench_branches_o RENAME TO pgbench_branches;
ALTER TABLE pgbench_history_o RENAME TO pgbench_history;
ALTER TABLE pgbench_tellers_o RENAME TO pgbench_tellers;

Key Features

No XID Wraparound: Eliminates transaction ID wraparound maintenance
No Table Bloat: Advanced storage management prevents table bloat
Cloud Storage: Native support for S3-compatible object storage
OLTP Optimized: Designed for transactional workloads
Improved Performance: Better space utilization and query performance

Note: Currently in Beta stage - thoroughly evaluate before production use.
