| Deployment | The documentation says KairosDB runs under Kubernetes and is mostly stateless, while Cassandra can be harder to run efficiently there. | The documentation describes standalone and cluster modes, and deployment as a binary with ETCD as its external dependency. |
| Product | KairosDB is a distributed time-series database built on Cassandra. | LinDB is an open-source, cloud-native, horizontally scalable distributed time-series database. |
| Security | The KairosDB pages reviewed do not state security certifications or compliance claims. | The introduction lists self-governance and defensive capability against malicious users as features. |
| Support | The project README directs users to a KairosDB discussion group for questions and community involvement. | The product page links to GitHub channels for feature requests, bug reports, and questions. |

LinDB
LinDB is an open-source distributed time-series database for IoT and IT operations monitoring. It stores and analyzes metrics across IaaS, PaaS, SaaS and application layers, using a schema-free model of metrics, tags and fields. LinQL provides SQL-like syntax for queries and cluster or database operations; data can be inserted and queried through an HTTP REST API, client connections and an admin console. Ingestion supports FlatBuffers, Protocol Buffers and InfluxDB protocols, with Go and Java client libraries listed. The system separates computation from storage and identifies ETCD as its only external dependency. It supports replicas, horizontal scaling, operation across multiple IDCs, and automatic minute, hour and day rollups. Deployment documentation covers standalone and cluster modes, with packages for Linux, Windows and macOS and a Docker guide for Linux. LinDB is free under Apache 2.0. Its data scope is limited to numeric time series with accuracy up to the second; it is not suited to text records or finer time precision.
