Simple, high performance SQL

Easily adopted, time-series optimized SQL

SELECT timestamp, symbol, price
FROM trades
WHERE timestamp IN '2024-06-21;1M';

-- Search time
SELECT timestamp, symbol, price
FROM trades
WHERE timestamp IN '2024-06-21;1M';

SELECT timestamp, symbol, avg(price)
FROM trades
SAMPLE BY 5m FILL(LINEAR);

-- Slice time
SELECT timestamp, symbol, avg(price)
FROM trades
SAMPLE BY 5m FILL(LINEAR);

SELECT timestamp, symbol, price
FROM trades
LATEST ON timestamp PARTITION BY symbol;

-- Navigate time
SELECT timestamp, symbol, price
FROM trades
LATEST ON timestamp PARTITION BY symbol;

SELECT timestamp, bid_price, ask_price
FROM bids
ASOF JOIN asks;

-- Merge time
SELECT timestamp, bid_price, ask_price
FROM bids
ASOF JOIN asks;

Search Time

Filter and search for specific timestamps with "WHERE"

Slice Time

Create time buckets and aggregate by intervals with "SAMPLE BY"

Navigate Time

Search time series from most recent values to oldest with "LATEST ON"

Merge Time

Join two tables based on timestamp where timestamps do not exactly match with "ASOF JOIN"

Market data meets open formats

Powering next gen market infrastructure

Hyper-fast, reliable, open source and cost effective

Domain specific functions: Use l2price to find the best price based on the book depth.
Flexible storage: Store order books in multi dimensional arrays (coming soon!).
SQL Window Functions: Calculate financial indicators such as Moving Average or VWAP.

Peak performance time-series

Hyper ingestion

For massive volumes of time-series data, trust a specialized time-series database. Timestamps are first-class, and blistering throughput is sustained even through the highest data cardinality. Deduplication and out-of-order ingestion also work right out-of-the-box.

Read the docs

Using QuestDB, we deliver time series datasets with real-time market data from a top 10 blockchain. This outperforms a legacy cloud-based data platform at a fraction of the cost, reducing TCO by >90%.
