zinc [options]

ZincSearch (formerly Zinc) is a lightweight, full-text search engine designed as an alternative to Elasticsearch. It provides log search and analytics with significantly lower resource requirements.ZincSearch features a web UI for management, REST API compatible with Elasticsearch's search syntax, and supports various data ingestion methods including bulk insert and fluentd/fluent-bit integration.The search engine is written in Go and uses Bluge as its indexing library. It runs as a single binary with embedded storage, requiring no external dependencies.Common use cases include log aggregation, application search, and replacing Elasticsearch in resource-constrained environments. The project has since evolved into OpenObserve.

Note: ZincSearch (now OpenObserve) is primarily configured via environment variables rather than command-line flags.

ZINC_FIRST_ADMIN_USER

Initial admin username (required on first run)

Initial admin password (required on first run)

Data storage directory (default: ./data)

Server bind address (default: 0.0.0.0)

Server port (default: 4080)

Maximum search results returned (default: 100)

Internal batch size for bulk indexing (default: 1024)

Number of shards for improved performance (default: 3)

Compression algorithm: snappy, s2, zstd (default: zstd)

Write-ahead log sync frequency (default: 1s)

Anonymous usage data (default: true)

Enable Prometheus metrics endpoint (default: false)

Set to "release" for production mode

Zinc is not a drop-in Elasticsearch replacement. While it supports similar query syntax, not all Elasticsearch features are implemented.For high-availability deployments, additional architecture (load balancers, replication) must be implemented manually.Memory usage scales with index size. Monitor resources for large deployments.First admin credentials must be set via environment variables before first run.
