AI-DBA Agent - Autonomous Database Administration

Early Access

HeliosDB AI-DBA Agent

A trained AI agent that continuously monitors, maintains, and optimizes your HeliosDB deployments. From anomaly detection to preventive maintenance to performance tuning — the AI-DBA Agent handles the operational complexity so your team can focus on building.

Available for HeliosDB Lite and Full editions. Three operating modes — Monitor, Advise, and Proactive — give you full control over the level of autonomy.

Monitoring

Proactive Monitoring

The AI-DBA Agent continuously monitors your database health, query performance, resource utilization, and storage patterns. It detects anomalies before they become incidents and alerts you with actionable recommendations.

Anomaly detection — ML-based detection of unusual query patterns, latency spikes, connection surges, and storage growth anomalies. Learns your normal baseline and flags deviations.
Performance degradation alerts — Detects gradual slowdowns in query execution, index efficiency, and I/O throughput before they impact users.
Predictive failure analysis — Monitors disk utilization trends, WAL growth rates, replication lag, and connection pool saturation to predict failures hours or days in advance.
Resource utilization tracking — CPU, memory, disk I/O, and network metrics correlated with query workloads for root-cause analysis.

Monitoring

# AI-DBA Agent: Real-time Monitoring

Health Status           HEALTHY
Uptime                  47d 13h 22m
Active Connections      84 / 200
QPS (current)           2,847
Avg Latency (p99)       4.2ms

# Anomaly Detected
WARN  Query latency p99 increased 340%
      in last 15min (4.2ms → 18.5ms)
      Table: orders
      Root cause: missing index on
        orders.customer_id
      Recommendation:
        CREATE INDEX idx_orders_cust
        ON orders(customer_id);

# Predictive Alert
INFO  Disk usage will reach 90% in ~6 days
      at current growth rate (2.1 GB/day)
      Recommendation: Enable compaction
        or provision additional storage

Maintenance

Autonomous Maintenance

In Proactive mode, the AI-DBA Agent performs routine database maintenance automatically within your configured maintenance window. Every action is logged to the audit trail with full before/after metrics.

Auto-vacuum & compaction — Schedules vacuum and storage compaction based on dead tuple ratios and LSM level sizes, not fixed intervals.
Index optimization — Detects unused indexes (cost without benefit), recommends missing indexes for frequent query patterns, and rebuilds fragmented indexes.
Query plan tuning — Analyzes slow query logs, identifies suboptimal plans, and updates statistics to guide the optimizer toward better execution strategies.
Storage rebalancing — Monitors per-column storage mode effectiveness and recommends switching between row, columnar, and dictionary modes based on actual access patterns.

SQL

-- What did AI-DBA do last night?
SELECT action, impact, started_at
FROM heliosdb_aidba.audit_log
WHERE started_at > NOW() - INTERVAL '24 hours'
ORDER BY started_at DESC;

-- action                  | impact
-- VACUUM orders           | 12% space reclaimed
-- CREATE INDEX idx_cust   | p99 latency -62%
-- DROP INDEX idx_unused   | 340MB freed
-- UPDATE STATISTICS users | plan accuracy +18%

-- Review pending recommendations
SELECT priority, recommendation, reason
FROM heliosdb_aidba.recommendations
WHERE status = 'pending'
ORDER BY priority;

-- priority | recommendation          | reason
-- HIGH     | ALTER COLUMN ... COLUMNAR | 94% scan workload
-- MEDIUM   | INCREASE wal_buffer_size  | WAL flush stalls

Resilience

Self-Healing

When things go wrong, the AI-DBA Agent responds automatically. It detects failures, reroutes connections, and initiates recovery — often resolving incidents before your team is even paged.

Automatic failover — On deployments with standbys (HeliosDB Lite primary/standby), detects primary node failure and promotes a standby. Failover for HeliosDB Full, which runs single-node today, is planned.
Connection rerouting — Transparently redirects active connections to healthy nodes during failover or rolling maintenance, with configurable retry policies.
Corrupt page detection & repair (planned) — Continuous checksumming of data pages and repair of a corrupted page from a standby copy are planned; page checksums are planned in HeliosCore, the storage engine behind HeliosDB Lite, and replica-based repair for HeliosDB Full is planned as well.
WAL recovery — Monitors WAL integrity and triggers point-in-time recovery when needed. Verifies recovery completeness and reports data consistency status.

Optimization

Performance Optimization

The AI-DBA Agent learns your workload patterns over time and continuously tunes the database for optimal performance. It adjusts configurations, recommends schema changes, and adapts resource allocation based on real usage data.

Query plan analysis — Identifies the most expensive queries, detects plan regressions, and suggests index or schema changes that would reduce execution time.
Index recommendations — Analyzes query patterns across all tables and recommends composite, partial, and covering indexes based on actual workload frequency and cost.
Configuration tuning — Adjusts heliosdb.toml parameters (buffer sizes, WAL settings, connection limits, compaction thresholds) based on observed resource utilization.
Workload-adaptive resources — Scales connection pools, cache sizes, and I/O priorities based on time-of-day workload patterns. Allocates more resources during peak hours automatically.
