Features
Innovative Design
Utilizes Write Ahead Log (WAL) for records, reducing I/O and memory usage.
Crazy Benchmark
Top performance with 39.372M rows/s, in-memory like speed, and WAL class durability.
Super Easy Integration
Identical HTTP API and TCP interfaces, all in JSON format.
Analytics Ready
Built-in support for data downsampling and aggregation.
Memory Efficient
Requires as low as 4MB of memory, perfect for IoT devices, benefiting in old SSD.
Built-in Streaming
Subscribe to keys and receive updates in real-time.
Battle-Tested
Trusted by IoT providers and used in production with code coverage for all logic.
Cross-Platform
Supports Windows, Linux/BSD, and macOS, perfect for edge devices.
Write Single Value
Allows you to write a single data point for a specific sensor, using an HTTP POST request with the required fields such as 'key', 'value', and 'time'.
Read Data with Time Range and Downsampling
Enables reading data for a specific sensor within a time range along with downsampling, using a JSON body specifying 'start timestamp', 'end timestamp', and 'downsampling'.
Read Last X Records
Retrieves the last X records for a specified sensor. The request requires the 'operation', 'limit', and 'key' fields.
Multi-Read Data with Time Range
Performs a multi-read for multiple sensors over a time range with downsampling. The request includes 'sensors', 'start timestamp', 'end timestamp', and 'downsampling'.
Multi-Read Last X Records
Fetches the last X records from multiple sensors using a list of sensor keys and the 'limit' specification.
Subscribe to a Key
Allows a subscription to updates from a specific sensor by specifying the 'operation' and 'key' fields.
Unsubscribe from a Key
Cancels a subscription to a specific sensor by specifying the 'operation' and 'key' fields.
Get All Keys
Retrieves a list of all sensor keys from the database by specifying the 'operation' field.
Initialize a New Key
Creates a new sensor key in the database by specifying the 'operation' and 'key' fields.
Rename a Key
Changes the name of an existing sensor key by specifying the 'old_sensor_name' and 'new_sensor_name' fields.
Delete a Key
Removes a specific key from the database by specifying the 'operation' and 'key' fields.
Flush All Data Points
Deletes all data points in your database with a simple 'flush' operation.
Patch Data Points
Allows updating or inserting multiple data points for a specific sensor. It involves specifying the 'key' and 'values' fields, where 'values' is a list of timestamps with corresponding data points.
