QuestDB consultants

Q: What does QuestDB do?

QuestDB is an open-source time-series database optimised for high-speed data ingestion and fast SQL queries. It stores timestamped data in a column-oriented format, enabling sub-second queries on datasets with billions of rows. It is commonly used for IoT, monitoring, and financial data.

Q: Can QuestDB integrate with existing BI and automation tools?

Yes. QuestDB supports the PostgreSQL wire protocol, which means tools like Grafana, Metabase, Tableau, and n8n can connect to it using standard PostgreSQL drivers. Data can be ingested through the InfluxDB Line Protocol, REST API, or CSV import.

Q: What are common use cases for QuestDB?

High-frequency IoT sensor data, real-time application and infrastructure monitoring, financial tick data analysis, fleet tracking, energy grid monitoring, and any workload that involves millions of time-stamped records that need to be queried quickly.

Q: How does QuestDB compare to TimescaleDB?

Both are time-series databases with SQL support, but they take different approaches. QuestDB uses its own storage engine built from scratch for speed, while TimescaleDB extends PostgreSQL. QuestDB tends to offer faster ingestion and query speeds for pure time-series workloads, while TimescaleDB offers broader PostgreSQL ecosystem compatibility.

Q: Is QuestDB suitable for production deployments?

Yes. QuestDB is used in production by companies handling billions of data points. It supports replication, snapshots for backup, and has configurable data retention. The open-source version is fully functional, with a cloud-managed option available for teams that prefer not to manage infrastructure.

Q: How does Osher help with QuestDB?

About QuestDB

QuestDB is a high-performance time-series database built for speed. It uses a column-oriented storage engine and supports SQL queries, making it accessible to anyone who already knows SQL while delivering query performance that outpaces traditional relational databases on time-series workloads by orders of magnitude. It is designed for scenarios where millions of rows need to be ingested per second and queried with sub-second response times.

Businesses use QuestDB for IoT data ingestion, real-time application monitoring, financial market data analysis, and operational analytics. Its PostgreSQL wire protocol compatibility means it works with existing BI tools like Grafana, Metabase, and Tableau without custom connectors. Data can be ingested via the InfluxDB Line Protocol, CSV import, or REST API, giving teams flexibility in how they feed data in.

Osher builds automated data processing pipelines on top of QuestDB for clients who need fast analytics on high-volume time-series data. We handle the deployment, schema design, ingestion pipeline setup, and dashboard creation — connecting QuestDB to your data sources and visualisation tools so insights are available in real time.

If your current database is struggling with time-series query performance or you are looking for a purpose-built solution for high-frequency data, reach out to discuss QuestDB.

How it works

We work hand-in-hand with you to implement QuestDB

As QuestDB consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate QuestDB with integrate and automate 800+ tools.

Step 1

Process Audit

We assess your current time-series data landscape — data sources, volumes, query patterns, and performance issues. This includes understanding how data is currently collected, stored, and analysed, and where bottlenecks exist.

Step 2

Identify Automation Opportunities

Based on the audit, we identify where QuestDB delivers the most value. This might include replacing slow queries on legacy databases, enabling real-time dashboards that were previously impractical, or building automated alerting on incoming data streams.

Step 3

Design Workflows

We design the QuestDB architecture — table schemas, partitioning strategy, retention policies, and ingestion pipelines. We also map out how QuestDB connects to your BI tools and alerting systems, defining the full data flow from source to insight.

Step 4

Implementation

Our team deploys QuestDB, configures tables with appropriate partitioning and retention settings, builds ingestion pipelines from your data sources, and sets up Grafana dashboards and n8n alerting workflows for real-time monitoring.

Step 5

Quality Assurance Review

We load-test QuestDB with realistic data volumes, verify query performance meets your requirements, and validate data accuracy across the full pipeline. Dashboard visualisations and alerting thresholds are tested with real scenarios.

Step 6

Support and Maintenance

After deployment, we monitor QuestDB performance, storage usage, and pipeline throughput. As your data volumes grow or new data sources come online, we adjust schemas, partitioning, and retention policies to maintain performance.
