InfluxDB Overview
InfluxDB is a time series database built for storing metrics, events, logs, and traces. InfluxData released the first version in 2013. It is the most widely deployed time series database in the world and consistently ranks #1 in the DB-Engines time series database category with a 21.60 score.
InfluxDB 3 is the most recent version of InfluxDB. Its architecture separates compute and storage, so each scales independently based on workload demands. InfluxDB 3 supports standard SQL and InfluxQL, a time-series-optimized query language with built-in functions for downsampling, windowed aggregations, and time-range filtering.
InfluxDB 3 is available in five deployment options:
- InfluxDB 3 Core: Open source, self-managed, MIT licensed.
- InfluxDB 3 Enterprise: Self-managed with enterprise capabilities including clustering, role-based access control, and automated backup and restore.
- InfluxDB Cloud Serverless: Fully managed, usage-based pricing, available across major cloud providers.
- InfluxDB Cloud Dedicated: Managed cloud on dedicated infrastructure for workloads requiring isolation or hardware-level configuration.
- Amazon Timestream for InfluxDB: InfluxDB fully managed by AWS, natively integrated
M3 Overview
M3 is a distributed time series database written entirely in Go. It is designed to collect a high volume of monitoring time series data, distribute storage in a horizontally scalable manner, and efficiently leverage hardware resources. M3 was initially developed by Uber as a scalable remote storage backend for Prometheus and Graphite and later open-sourced for broader use.
InfluxDB for Time Series Data
InfluxDB is the right choice when the workload is time series by nature: data arrives continuously, records are rarely modified after they are written, queries span time ranges, and volume grows with the number of sources rather than user activity.
InfluxDB is purpose-built for these workloads:
- Infrastructure and application observability: server metrics, container telemetry, Kubernetes monitoring
- Machine learning and AI: High-frequency feature data, model performance metrics, and inference telemetry at the latency and scale ML pipelines require
- IoT and industrial sensor data: high-frequency writes from large device fleets
- Energy systems: smart meters, battery storage telemetry, renewable asset monitoring
- Network telemetry: gNMI streaming, SNMP at scale, NetFlow records
- Satellite and aerospace: High-frequency telemetry from satellites, launch vehicles, and ground systems where data volume is extreme and decisions are time-sensitive
- Financial time series: tick data, price feeds, OHLCV aggregations
At high data volumes, InfluxDB’s columnar storage and object storage backend compress time series data aggressively and store it at a fraction of the cost of in-memory or block storage.
M3 for Time Series Data
M3 is specifically designed for time-series data. It is a distributed and scalable time-series database optimized for handling large volumes of high-resolution data points, making it an ideal solution for storing, querying, and analyzing time-series data.
M3’s architecture focuses on providing fast and efficient querying capabilities, as well as high ingestion rates, which are essential for working with time-series data. Its horizontal scalability and high availability ensure that it can handle the demands of large-scale deployments and maintain performance as data volumes grow.
InfluxDB Key Concepts
-
Columnar storage: InfluxDB stores data in a column-oriented format using both open source and proprietary standards for persistent storage and Apache Arrow as the in-memory representation. Columnar storage produces strong compression ratios and fast time-range reads.
-
Data model: InfluxDB organizes data into databases, measurements (equivalent to tables), tags (indexed identifiers used for filtering), and fields (the measured values). InfluxDB 3 supports unlimited tables and columns. Data models evolve without schema migrations or predefined column limits.
-
Query languages: InfluxDB supports standard SQL and InfluxQL. InfluxQL includes built-in time-series functions: gap filling, window aggregations, downsampling, and rate calculations from counter data.
-
Decoupled architecture: InfluxDB 3 separates ingestion, query compute, and storage into independently scalable components. Teams tune each layer to workload requirements rather than provisioning for peak across all three simultaneously.
-
Retention policies: Users configure retention policies that automatically expire data after a defined duration. No manual partition drops, retention scripts, or index rebuilds required.
-
Telegraf integration: Telegraf, InfluxData’s open-source data collection agent, connects to 400+ data sources out of the box and writes directly to InfluxDB. It is part of the standard telemetry collection stack for tens of thousands of teams worldwide.
-
Unlimited Cardinality: The InfluxDB 3 storage engine enables high-performance queries across tables with millions of columns without impacting query performance.
M3 Key Concepts
- Time Series Compression: M3 has the ability to compress time series data, resulting in significant memory and disk savings. It uses two compression algorithms, M3TSZ and protobuf encoding, to achieve efficient data compression.
- Sharding: M3 uses virtual shards that are assigned to physical nodes. Timeseries keys are hashed to a fixed set of virtual shards, making horizontal scaling and node management seamless.
- Consistency Levels: M3 provides variable consistency levels for read and write operations, as well as cluster connection operations. Write consistency levels include One (success of a single node), Majority (success of the majority of nodes), and All (success of all nodes). Read consistency level is One, which corresponds to reading from a single nod
InfluxDB Architecture
InfluxDB 3 separates data ingestion, querying, compaction, and garbage collection into components that operate independently. This separation allows compute and storage to scale in different directions based on actual workload requirements.
Data written to InfluxDB flows through ingesters with millisecond-level latency and is immediately queryable. A background compactor consolidates new files and moves them to object storage. The query layer pulls seamlessly from both in-flight ingester data and object storage, so there is no gap between data arrival and query availability.
Object storage handles long-term persistence at low cost. Teams retain data at higher frequencies and for longer periods without driving up infrastructure costs on expensive storage tiers.
M3 Architecture
M3 is designed to be horizontally scalable and handle high data throughput. It uses fileset files as the primary unit of long-term storage, storing compressed streams of time series values. These files are flushed to disk after a block time window becomes unreachable. M3 has a commit log, equivalent to the commit log or write-ahead-log in other databases, which ensures data integrity. Client Peer streaming is responsible for fetching blocks from peers for bootstrapping purposes. M3 also implements caching policies to optimize efficient reads by determining which flushed blocks are kept in memory.
