Performance Expertise

Database Performance Engineering

From Slow Queries to Production-Ready Performance

Sreenivas has significant experience investigating and resolving real database performance problems by connecting symptoms to evidence, execution behavior and root causes.

Performance tuning is not about changing random parameters. Students learn to identify the actual bottleneck, collect evidence, understand the execution plan, determine the root cause, implement the appropriate solution and validate the improvement.

  • Slow Query Analysis
  • SQL Optimization
  • Query Execution Plans
  • EXPLAIN
  • EXPLAIN ANALYZE
  • Index Strategy
  • Index Optimization
  • PostgreSQL Query Tuning
  • SQL Server Performance Tuning
  • CPU Bottleneck Analysis
  • Database Wait Analysis
  • Lock Analysis
  • Blocking Sessions
  • Deadlocks
  • Large Table Optimization
  • Partitioning
  • Database Monitoring
  • Production Incident Troubleshooting

Beyond Tutorials

Learn the Concept, Not Just the Command

Commands are useful only when you understand why they work, what happens internally and how to respond when production does not behave as expected.

Physical backup example

pg_basebackup ...

Then go deeper

  • Why physical backup is required
  • How physical backup works
  • How WAL is involved
  • How replication uses WAL
  • Configuration
  • Internal behavior
  • Common failures
  • Production troubleshooting

Indexing example

CREATE INDEX ...

Make the right indexing decision

  • Why the index is required
  • Choosing an index type
  • B-Tree vs Hash vs GiST vs GIN vs BRIN
  • Planner decisions
  • EXPLAIN validation
  • EXPLAIN ANALYZE validation
  • Write impact
  • Maintenance
  • When not to create an index

Concept → Demonstration → Hands-on Practice → Troubleshooting → Production Scenario

Career Preparation

Job-Oriented PostgreSQL Training

The objective is not simply to complete a syllabus. Students build practical DBA capabilities they can apply at work.

  • Installing and configuring PostgreSQL
  • Managing databases, users, security and privileges
  • Backup, restore and Point-in-Time Recovery
  • Configuring replication and managing standby databases
  • Understanding HA and troubleshooting replication
  • Monitoring PostgreSQL and investigating performance
  • Reading execution plans and choosing appropriate indexes
  • Investigating locks and detecting deadlocks
  • Vacuum and Autovacuum
  • PostgreSQL upgrades and database migrations
  • Troubleshooting production problems

The goal is to prepare students to think and work like a PostgreSQL DBA—not simply memorize PostgreSQL commands.

Current Training Focus

Training Philosophy

“Database administration cannot be mastered by memorizing commands. A good DBA should understand what happens internally, why a problem occurs, how to diagnose it and how to resolve it safely in a production environment.”
