Your query is running slowly. What do you check FIRST?
A) Add an INDEX
B) Run EXPLAIN
C) Rewrite the query
D) Check server resources
Choose wisely! โก
#MySQL #DatabasePerformance
Database performance is not one number. Write path, compression, latest-value reads, long-range scans, and aggregations all matter differently. Small design choices at the data layer become big operational habits. #DatabasePerformance #TimeSeries
Database connection pooling matters.
Opening a new database connection for every request adds unnecessary overhead.
Reuse managed connections and configure pool limits for your workload.

DATABASE PERFORMANCE
Your application might have a great UI, clean code, and powerful featuresโbut if database queries are slow, the entire user experience can suffer.
My approach:
#DatabasePerformance #DatabaseOptimization #FullStackDeveloper #SoftwareEngineering #PostgreSQL
A slow MongoDB query needs evidence, not guesses.
Use explain() to inspect the query plan and understand how documents and indexes are examined.
Measure before changing indexes.

Offset pagination can become expensive on large datasets.
Cursor-based pagination can be more efficient when designed around a stable sort key.
Choose pagination based on data size and access patterns.

๐ An index exists, but PostgreSQL still chooses a sequential scan. Do you know why? Learn to investigate query plans like a pro. #DatabasePerformance

The database performance meeting identified missing indexes, bad queries, and insufficient willingness to investigate either.
A larger server survived the architecture review. The query plan was not invited.

Migrating SAP HANA to the cloud splits your visibility between on-prem and cloud tools. SolarWinds DPA reads wait times the same way on both sides, so you catch regressions before users do.
