ddb_client

The DalmatinerDB Client is an Erlang library that provides a TCP interface for interacting with the DalmatinerDB time series database. It facilitates efficient data ingestion and retrieval, supporting both stream-based writes and flexible read operations with configurable consistency settings.

Key Features

• Stream Mode Writing — Optimizes data ingestion by switching connections to stream mode, allowing batched writes to a specific bucket.
• Binary Data Encoding — Integrates with the mmath library to encode time series data into binary format before transmission.
• Flexible Read Operations — Supports reading data points by timestamp and count, with optional consistency parameters like read repair and quorum settings.
• Connection Pooling — Recommends using connection pools (e.g., via Pooler) for efficient multi-bucket data writing by reusing connections.
• Protocol Compliance — Implements the DalmatinerDB network protocol, ensuring reliable communication with the database server.

Philosophy

The client is designed for performance and simplicity, leveraging Erlang's concurrency model to handle time series data efficiently while providing clear, functional APIs for database interactions.
