Choosing the right database is a critical choice when building any software application. All databases have different strengths and weaknesses when it comes to performance, so deciding which database has the most benefits and the most minor downsides for your specific use case and data model is an important decision. Below you will find an overview of the key concepts, architecture, features, use cases, and pricing models of InfluxDB and Apache Pinot so you can quickly see how they compare against each other.

The primary purpose of this article is to compare how InfluxDB and Apache Pinot perform for workloads involving time series data, not for all possible use cases. Time series data typically presents a unique challenge in terms of database performance. This is due to the high volume of data being written and the query patterns to access that data. This article doesn't intend to make the case for which database is better; it simply provides an overview of each database so you can make an informed decision.

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

Apache Pinot Overview

Apache Pinot is a real-time distributed OLAP datastore, designed to answer complex analytical queries with low latency. It was initially developed at LinkedIn and later open-sourced in 2015. Pinot is well-suited for handling large-scale data and real-time analytics, providing near-instantaneous responses to complex queries on large datasets. It is used by several large organizations, such as LinkedIn, Microsoft, and Uber.


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.

Apache Pinot for Time Series Data

Apache Pinot is a solid choice for working with time series data due to its columnar storage and real-time ingestion capabilities. Pinot’s ability to ingest data from streams like Apache Kafka ensures that time series data can be analyzed as it is being generated, in addition to having options for bulk ingesting data.


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.

Apache Pinot Key Concepts

  • Segment: A segment is the basic unit of data storage in Pinot. It is a columnar storage format that contains a subset of the table’s data.
  • Table: A table in Pinot is a collection of segments.
  • Controller: The controller manages the metadata and orchestrates data ingestion, query execution, and cluster management.
  • Broker: The broker is responsible for receiving queries, routing them to the appropriate servers, and returning the results to the client.
  • Server: The server stores segments and processes queries on those segments.

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.

Apache Pinot Architecture

Pinot is a distributed, columnar datastore that uses a hybrid data model, combining features of both NoSQL and SQL databases. Its architecture consists of three main components: Controller, Broker, and Server. The Controller manages metadata and cluster operations, while Brokers handle query routing and Servers store and process data. Pinot’s columnar storage format enables efficient compression and quick query processing.

InfluxDB Features

High-performance storage and querying

InfluxDB 3 is optimized for time series at every layer: ingestion, storage, and query execution. InfluxDB 3.10 delivers significantly faster query performance compared to prior InfluxDB 3 releases, with the most pronounced gains on single-series lookups, real-time telemetry queries, and metadata operations. Performance varies by workload.

Retention policies

InfluxDB automatically expires data after a configured duration. No external orchestration required.

Data compression

InfluxDB 3’s storage engine delivers strong compression ratios on time series data. Background compaction continuously consolidates smaller files into larger ones that are cheaper to store and faster to query.

Horizontal scaling and clustering

InfluxDB 3 Enterprise supports horizontal scaling and clustering, distributing data and query load across nodes for performance and fault tolerance.

Data tiering

InfluxDB 3 automatically moves data between hot and cold storage tiers. Recent data stays accessible for low-latency queries. Older data moves to object storage, where it remains queryable at lower cost without manual lifecycle management.

Row-level deletions

Users delete individual data points or subsets within a table without dropping entire tables or databases.

Auto-Distinct Value Caching

InfluxDB 3.10 automatically creates caches for metadata queries, making operations like SHOW TAG VALUES significantly faster without manual cache configuration.

Processing Engine

InfluxDB 3 runs Python code directly inside the database for real-time transformations, anomaly detection, and forecasting. Plugins trigger on a schedule, via HTTP requests, or on data write with no external processing layer required.

InfluxDB handles application performance monitoring, user behavior tracking, and financial data analysis in real time. SQL and InfluxQL support lets teams run complex aggregations and time-windowed queries without a dedicated analytics layer.

Infrastructure and application monitoring

InfluxDB handles the cardinality and write throughput that infrastructure monitoring generates at scale: millions of unique tag combinations across hosts, services, containers, and endpoints. Teams query recent and historical data spanning months or years without separate storage tiers or query engines.

Satellite & Aerospace

InfluxDB stores and analyzes high-frequency telemetry from satellites, launch vehicles, and ground systems where data volume is extreme and query latency affects operational decisions. Object storage tiering keeps years of mission data accessible without runaway infrastructure costs.

Industrial AI

InfluxDB ingests continuous signals from PLCs, SCADA systems, and industrial sensors at the frequencies predictive maintenance and process optimization models require. The Processing Engine runs detection and forecasting plugins in-database, reducing latency between sensor data and actionable output.

Data historian augmentation

InfluxDB extends legacy data historians by capturing the high-resolution, high-frequency process data that traditional historians compress, downsample, or age out. Open SQL and InfluxQL access frees that data from closed historian interfaces, while object storage tiering retains full-fidelity history at a fraction of the cost of expanding the existing system. Teams bridge plant-floor signals into modern analytics or ML pipelines and run Processing Engine plugins against live and archived data, modernizing without ripping out the historian they already depend on.
