FrostDB is an embeddable columnar database written in Go that uses Apache Parquet for storage and Apache Arrow for query-time processing. It supports semi-structured schemas with dynamic columns and is optimized for write-heavy workloads with occasional analytical queries.

Use cases

• embed a columnar analytics database in a Go application
• store and query write-heavy observability data like profiles and metrics
• query semi-structured data with columns added at runtime
• analyze immutable datasets with Arrow-based DataFrame queries
• replace running a separate database server with an in-process store

When to choose

• you are developing in Go and want an embedded columnar database
• your datasets are immutable and don't need updates or deletes
• your schema has dynamic columns that grow at runtime
• your workload is write-heavy with occasional analytical queries

When to avoid

• you need a standalone database server
• you need to update or delete existing data
• you query by rows instead of columns
• you are not developing in Go
• you need a production-ready database with stable APIs
