My contribution

At Bed Bath & Beyond, tuned PostgreSQL queries, added indexes on relevant columns, and worked on triggers for audit-record updates.

Technical approach

Worked on query tuning, relevant-column indexes, and triggers for audit-record updates.

  • Tune queries and add indexes for relevant columns.
  • Use database triggers for audit-record updates alongside the query work.

Documented implementation areas

  1. 01Query tuning
  2. 02Relevant-column indexes
  3. 03Audit-update triggers
PostgreSQL Query & Audit Improvements: simplified illustration of the documented workflow or implementation areas. Infrastructure and confidential implementation details are intentionally omitted.

Outcome & lessons

Improved query implementation and audit-record maintenance; no measured performance percentage is claimed.

Query changes and audit behavior solve different needs: access to operational data and a record of updates. Measured timing and benchmark results are not published.
