# InfluxDB OSS v1 documentation

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

InfluxDB is a [time series database](https://www.influxdata.com/time-series-database/) designed to handle high write and query loads. InfluxDB OSS v1 is purpose-built to handle any use case involving large amounts of timestamped data and is an integral component of the [TICK stack](https://influxdata.com/time-series-platform/).

Common use cases include:

-   Infrastructure and DevOps monitoring
-   Application metrics and performance monitoring
-   IoT sensor data collection
-   Real-time analytics
-   Events handling

#### InfluxDB Cloud 1 users

**InfluxDB Cloud 1** (InfluxCloud 1.x) is based on InfluxDB Enterprise v1. Use the [Enterprise v1 documentation](/enterprise_influxdb/v1/) instead.

-   **InfluxDB Cloud 1 Support**: [help.influxcloud.net](https://help.influxcloud.net)
-   **Migrate**: Consider [migrating to InfluxDB 3](/platform/#migration-to-influxdb-3) (Enterprise, Cloud Serverless, or Cloud Dedicated) with v1 API compatibility

## Key features

InfluxDB v1.12 supports the following features for working with time series data.

-   Custom high performance datastore written specifically for time series data. The TSM engine allows for high ingest speed and data compression
-   Written entirely in Go. It compiles into a single binary with no external dependencies.
-   Simple, high performing write and query HTTP APIs.
-   Plugins support for other data ingestion protocols such as Graphite, collectd, and OpenTSDB.
-   Expressive SQL-like query language tailored to easily query aggregated data.
-   Tags allow series to be indexed for fast and efficient queries.
-   Retention policies efficiently auto-expire stale data.
-   Continuous queries automatically compute aggregate data to make frequent queries more efficient.

InfluxDB OSS v1 runs on a single node. If you require high availability to eliminate a single point of failure, consider [InfluxDB 3 Enterprise](/influxdb3/enterprise/), InfluxDB’s next generation that supports multi-node clustering, allows infinite series cardinality without impact on overall database performance, and brings native SQL support and improved InfluxQL performance.
