## What it is
An expressive DynamoDB client library for Go built on the official AWS SDK v2. It provides a fluent, struct-tag-based API for putting, getting, querying, and scanning items with expression building.

## Use cases
- interact with dynamodb from go
- map go structs to dynamodb items
- query and scan dynamodb tables with filters
- build dynamodb condition and filter expressions
- crud operations on aws dynamodb

## When to choose
- you use Go and want a friendlier API than raw AWS SDK calls to DynamoDB
- you want struct-tag based serialization like encoding/json
- you need expressive query, scan, and conditional write helpers

## When to avoid
- you use a language other than Go
- you need a database other than DynamoDB
- you prefer the official AWS SDK's low-level document API directly

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, orm
- domain: databases, developer-tools, backend
- platform: go, windows, cross-platform
- tags: dynamodb, aws-sdk-v2, nosql, struct-mapping, query-builder, linux, macos
