LanguageProject Introduction
Summary
Apache Pinot is a real-time distributed OLAP (Online Analytical Processing) datastore developed to power user-facing analytical applications. It excels at providing immediate insights from high-velocity, high-volume data streams.
Problem Solved
Traditional databases often struggle to provide real-time, low-latency analytical queries on rapidly changing, large-scale datasets. Pinot is built specifically to address this challenge for Online Analytical Processing (OLAP) workloads.
Core Features
Low-Latency Queries
Achieve query latency in milliseconds, even on datasets spanning terabytes.
High Ingestion Rate
Handle millions of events per second from streaming sources like Kafka or Kinesis.
Columnar Store & Indexing
Utilizes columnar storage, various indexes (sorted, inverted, star-tree), and intelligent pruning techniques for query performance.
Tech Stack
Java
Apache Helix
Apache Zookeeper
Apache Kafka
Apache Pulsar
gRPC
Use Cases
Apache Pinot is designed for scenarios where real-time analytical queries on large datasets are critical. Common use cases include:
User-Facing Analytics & Dashboards
Details
Powering user-facing dashboards within applications (e.g., LinkedIn's Who's Viewed Your Profile, Uber's real-time monitoring).
User Value
Provides instant insights directly within the application, enhancing user experience and engagement.
Real-time Monitoring & Anomaly Detection
Details
Real-time monitoring of business metrics, application performance, network traffic, or IoT data streams.
User Value
Enables immediate detection of issues or trends, allowing for quicker response times.
Clickstream and User Behavior Analysis
Details
Analyzing user behavior clicks, impressions, and activity streams in real-time for personalization or immediate segmentation.
User Value
Allows for instant understanding of user interactions to drive personalization or targeted actions.
