Confluo is a C++ system for real-time monitoring and analysis of data streams, supporting high-throughput concurrent writes of millions of data points, millisecond online queries, and low-CPU ad-hoc queries. It runs as a server daemon with C++, Python, and Java client APIs, offering indexes, filters, aggregates, and triggers over Atomic MultiLogs.

Use cases

• monitor millions of performance metrics in real time
• run millisecond-latency queries over streaming data
• install triggers that fire on aggregate thresholds like high latency
• ingest concurrent writes from multiple data streams
• run ad-hoc filters and aggregates with minimal CPU overhead
• store and query structured log records with indexes

When to choose

• you need high-throughput stream ingestion with concurrent writers
• you want millisecond online queries plus ad-hoc analytics on the same data
• you need triggers and aggregates over streaming metrics
• you are on Linux or macOS and comfortable building C++ software

When to avoid

• you need Windows support
• you want a managed or actively developed product with recent releases
• you need SQL or rich ecosystem integrations rather than a custom API
• your workload is small enough for a standard time-series database
