4. What is TimescaleDB❓
5. TimescaleDB: An overview TimescaleDB = PostgreSQL for time-series Leading open-source relational database for time-series data Packaged as PostgreSQL extension Optimized for: • Consistently high ingest • High cardinality • Fast, complex queries • High performance at scale
6. Developer productivity TimescaleDB provides all the power and convenience of PostgreSQL, including a proven relational database, the full SQL language, the rich and vibrant PostgreSQL tools ecosystem, and all the developer tools supported by PostgreSQL.
7. TimescaleDB is PostgreSQL with time-series superpowers Supercharged PostgreSQL Rely on the same PostgreSQL you know and love, with full SQL, rock-solid reliability, and a massive ecosystem. Accelerated performance Achieve 10-100x faster queries than PostgreSQL, InfluxDB, and MongoDB. Native optimizations for time-series. Massive scale Write millions of data points per second. Store 100s of terabytes or petabytes. Don’t worry about cardinality. Relational & time series, together Simplify your stack, ask more complex questions, and build more powerful applications. Worry-free operations Let us run TimescaleDB for you, fully managed on AWS, Azure, or GCP in 75+ regions. Access top-rated support. Lower costs Spend less with 94% compression rates from best-in-class algorithms and other performance improvements.
9. Highly scalable data ingestion Write millions of data points per second from relentless streams of time-series data.

25. Enterprise- grade data management TimescaleDB includes advanced data management not found in traditional relational databases, including data retention, downsampling, data tiering, hypertable and schema management, data lifecycle management, and more.
27. Innovative time-series analytics TimescaleDB includes a number of time-oriented features not found in traditional relational databases, including functions for complex windowing, gap-filling, interpolation, and much more.
28. Cons Schema Design ✅ Can overcome for certain use-cases eg) DevOps & Prometheus metrics Higher storage overhead ✅ Native compression in Timescale 1.7 Scale up-only architecture ✅ Scale out (multi-node) in TimescaleDB 2.0 (Potentially) Complex to tune ✅ Timescale team is here to help!
29. Popular Use Cases
30. Time-series data is everywhere -- What is the change of memory consumption for each -- of my k8s containers over the past 10 minutes? SELECT time_bucket('10 seconds', time) AS period, container_id, avg(free_mem) FROM metrics WHERE time > NOW () - interval '10 minutes' GROUP BY period, container_id ORDER BY period DESC, container_id; -- How much of my advertising inventory is unsold or -- has unmet demand over recent time intervals? SELECT period, total_sold, (total_supply - total_sold) AS total_unsold, (total_demand - total_sold) AS total_unmet FROM ( SELECT time_bucket('10 seconds', time) AS period, SUM(sold) AS total_sold, SUM(supply) AS total_supply, SUM(demand) AS total_demand FROM inventory WHERE time > NOW () - interval '10 minutes' GROUP BY period ) AS data ORDER BY period DESC; -- For a specific machine, what are its avg, min, and max temp -- readings over time to ensure it's in proper operating range? SELECT time_bucket('10 seconds', time) AS period, min(temperature) AS min_temp, avg(temperature) AS avg_temp, max(temperature) AS max_temp, FROM measurements WHERE machine_id = 'C931baF7' AND time > NOW() - interval '150s' GROUP BY period ORDER BY period DESC; -- For financial ticker 'TIMS', what the the open, close, high, and -- low prices (and its trade volume) over the past 30 days? SELECT time_bucket('1 day', time) AS day, first(price, time) AS open, last(price, time) AS close, max(price) AS high, min(price) AS low, sum(volume) AS volume FROM prices WHERE asset_code = 'TIMS' AND time > NOW() - interval '30d' GROUP BY day ORDER BY day ASC; DevOps Monitoring Application Metrics Internet of Things Financial Data
