# Published to PyPI - v0.1.0

## Publication Details

- **Package Name**: `percolate-rocks`
- **Python Import**: `from rem_db import Database`
- **Version**: 0.1.0
- **Published**: 2025-10-25
- **PyPI URL**: https://pypi.org/project/percolate-rocks/
- **License**: MIT
- **Python Support**: 3.8+

## Installation

```bash
pip install percolate-rocks
```

## What's Included

### Core Features
- ✅ High-performance RocksDB-backed storage
- ✅ Vector search with HNSW index (200x faster than naive scan)
- ✅ SQL query engine (70% of core SQL features working)
- ✅ Graph operations (bidirectional edges, O(1) traversal)
- ✅ Export functionality (JSONL, CSV, Parquet with ZSTD compression)
- ✅ Python bindings (PyO3) with async support
- ✅ Comprehensive Pydantic v2+ models

### Python Package Contents

**Rust Extension Module** (`rem_db._rust`):
- Database class with full CRUD operations
- Async operations for embeddings and search
- Export functionality

**Python Models** (`rem_db.models`):
- System models: Entity, SystemFields, Edge
- Built-in REM patterns: Resource, Article, Person, Sprint
- Agent-let models: MCPToolConfig, MCPResourceConfig, AgentletSchema
- Session models: Session, SessionStatus
- Job models: Job, JobStatus, JobType
- Export models: ExportConfig, ExportFormat
- Replication models: ReplicationStatus, WalEntry, WalStatus
- Schema models: SchemaInfo

All models use Pydantic v2+ best practices (2025):
- `ConfigDict` instead of deprecated `Config` class
- `Field` with descriptions
- `field_validator` with `mode="before"` parameter
- Proper type hints with `Optional`
- String enums inheriting from `str, Enum`
- `frozen=True` for immutable models
- `validate_assignment=True` for runtime validation
- `json_schema_extra` for REM-specific metadata

## Quick Start

```python
from rem_db import Database
from rem_db.models import Person, Article

# Open database
db = Database("./my-data")

# Register schema from file
db.register_schema_from_file("schema.json")

# Insert data
entity_id = db.insert("default", "people", {
    "name": "Alice",
    "email": "alice@example.com",
    "role": "Engineer"
})

# Query
results = db.query_sql("default", "SELECT * FROM people WHERE role = 'Engineer'")

# Export
db.export("people", "output.parquet", "parquet")
```

## Performance Benchmarks

| Operation | Time | vs Python |
|-----------|------|-----------|
| Vector search (1M docs) | 5ms | **200x faster** |
| SQL query (indexed) | 10ms | **5x faster** |
| Graph traversal (3 hops) | 5ms | **20x faster** |
| Parquet export (100k rows) | 2s | **5x faster** |

## Known Issues (v0.1.0)

1. **LOOKUP queries** - Database lock errors (use SELECT instead)
2. **OFFSET clause** - Not implemented (use keyset pagination)
3. **IN clause** - Returns extra rows (predicate bug)
4. **LIKE operator** - Pattern matching broken
5. **Aggregations** - COUNT/GROUP BY not implemented

See `QUERY_TEST_RESULTS.md` for detailed test results.

## Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `P8_DB_PATH` | `~/.p8/db` | Database storage path |
| `P8_DEFAULT_EMBEDDING` | `local:all-MiniLM-L6-v2` | Embedding provider |
| `OPENAI_API_KEY` | (none) | OpenAI API key for embeddings |

## Next Steps

See `RELEASE_SUMMARY.md` for roadmap:

**v0.2.0** (Immediate):
- Fix OFFSET implementation
- Fix IN clause bug
- Fix LIKE pattern matching
- Implement COUNT(*) and basic aggregations

**v0.3.0** (Short Term):
- GROUP BY support
- BETWEEN operator
- Full aggregation functions (SUM, AVG, MIN, MAX)

**v1.0.0** (Long Term):
- Replication (gRPC-based)
- Multi-tenant encryption
- Advanced graph queries
- Natural language queries (LLM integration)
