Time-series data grows exponentially, but query performance shouldn't degrade proportionally. Traditional time-series databases struggle with text-heavy observability workloads.

Advanced Indexing for Time-Series

GreptimeDB time-series capabilities now include sophisticated full-text indexing, bridging the gap between structured metrics and unstructured logs.

Dual-Engine Architecture Benefits

The Flow Engine enhancement supports:

• Batching mode for historical analysis
• Streaming mode for real-time processing
• Time-series database optimization
