SawitDB

<div align="center">

</div>

SawitDB is a unique database solution stored in .sawit binary files.

The system features a custom Hybrid Paged Architecture similar to SQLite but supercharged with Object Caching, using fixed-size 4KB pages to ensure efficient memory usage and near-instant access. What differentiates SawitDB is its unique Agricultural Query Language (AQL), which replaces standard SQL keywords with Indonesian farming terminology.

Now available on NPM! Connect via TCP using sawitdb:// protocol.

Features

• Hybrid Paged Architecture: Data is stored in 4096-byte binary pages, but hot data is cached as native Objects for zero-copy reads.
• Single File Storage: All data, schema, and indexes are stored in a single .sawit file.
• High Stability: Uses 4KB atomic pages. More stable than a coalition government.
• Data Integrity (Anti-Korupsi): Implements strict fsync protocols. Data cannot be "corrupted" or "disappear" mysteriously like social aid funds (Bansos). No "Sunat Massal" here.
• Crash Recovery: Uses Write-Ahead Logging (WAL). Guarantees data always returns after a crash. Unlike a fugitive (Buronan) who is "hard to find".
• Zero Bureaucracy (Zero Deps): Built entirely with standard Node.js. No unnecessary "Vendor Pengadaan" or "Mark-up Anggaran".
• Transparansi: Query language is clear. No "Pasal Karet" (Ambiguous Laws) or "Rapat Tertutup" in 5-star hotels.
• Speed: Faster than printing an e-KTP at the Kelurahan.
• Network Support (NEW): Client-Server architecture with Multi-database support and Authentication.
• True Multi-Threading (NEW): Worker Pool architecture separates IO (Main Thread) from CPU (Worker Threads).
• Advanced SQL (NEW): Support for JOIN (Left/Right/Full/Cross), JAVING, DISTINCT, and more.
• NPM Support (NEW): Install via npm install @wowoengine/sawitdb.
• AKAD Transactions (v3.0): ACID-compliant transactions with MULAI AKAD, SAHKAN, BATALKAN.
• TEROPONG Views (v3.0): Virtual tables with PASANG TEROPONG and BUANG TEROPONG.
• KENTONGAN Triggers (v3.0): Event hooks for INSERT/UPDATE/DELETE.
• SOP Procedures (v3.0): Stored scripts with SIMPAN SOP and JALANKAN SOP.
• CABANG Replication (v3.0): Primary-Replica synchronization via Change Data Capture.
• DB Event & CDC (v3.0): Change Data Capture with CPO adapter and custom event hooks (OnTableCreated, OnTableInserted, etc).
• BLUSUKAN Full-Text Search (v3.0): Inverted Index search with BLUSUKAN KE ... CARI.
• POS RONDA Security (v3.0): Role-Based Access Control with BERI IZIN and CABUT IZIN.

Filosofi

Filosofi (ID)

SawitDB dibangun dengan semangat "Kemandirian Data". Kami percaya database yang handal tidak butuh Infrastruktur Langit yang harganya triliunan tapi sering down. Berbeda dengan proyek negara yang mahal di budget tapi murah di kualitas, SawitDB menggunakan arsitektur Single File (.sawit) yang hemat biaya. Backup cukup copy-paste, tidak perlu sewa vendor konsultan asing. Fitur fsync kami menjamin data tertulis di disk, karena bagi kami, integritas data adalah harga mati, bukan sekadar bahan konferensi pers untuk minta maaf.

Philosophy (EN)

SawitDB is built with the spirit of "Data Sovereignty". We believe a reliable database doesn't need "Sky Infrastructure" that costs trillions yet goes down often. Unlike state projects that are expensive in budget but cheap in quality, SawitDB uses a cost-effective Single File (.sawit) architecture. Backup is just copy-paste, no need to hire expensive foreign consultants. Our fsync feature guarantees data is written to disk, because for us, data integrity is non-negotiable, not just material for a press conference to apologize.

Dual Syntax Support

SawitDB introduces the Generic Syntax alongside the classic Agricultural Query Language (AQL), making it easier for developers familiar with standard SQL to adopt.

| Operation | Agricultural Query Language (AQL) | Generic SQL (Standard) | | :--- | :--- | :--- | | Create DB | BUKA WILAYAH sales_db | CREATE DATABASE sales_db | | Use DB | MASUK WILAYAH sales_db | USE sales_db | | Show DBs | LIHAT WILAYAH | SHOW DATABASES | | Drop DB | BAKAR WILAYAH sales_db | DROP DATABASE sales_db | | Create Table | LAHAN products | CREATE TABLE products | | Insert | TANAM KE products (...) BIBIT (...) | INSERT INTO products (...) VALUES (...) | | Select | PANEN * DARI products DIMANA ... | SELECT * FROM products WHERE ... | | Update | PUPUK products DENGAN ... | UPDATE products SET ... | | Delete | GUSUR DARI products DIMANA ... | DELETE FROM products WHERE ... | | Indexing | INDEKS products PADA price | CREATE INDEX ON products (price) | | Aggregation | HITUNG SUM(stock) DARI products | Same Syntax | | Begin Transaction | MULAI AKAD | BEGIN TRANSACTION | | Commit | SAHKAN | COMMIT | | Rollback | BATALKAN | ROLLBACK | | Create View | PASANG TEROPONG [nama] SEBAGAI [query] | CREATE VIEW [nama] AS [query] | | Drop View | BUANG TEROPONG [nama] | DROP VIEW [nama] | | Trigger | PASANG KENTONGAN [nama] PADA ... | CREATE TRIGGER [nama] ON ... | | Procedure | SIMPAN SOP [nama] SEBAGAI ... | CREATE PROCEDURE [nama] AS ... | | Replication | SETEL CABANG SEBAGAI ... | CONFIGURE REPLICATION AS ... | | Search (FTS) | BLUSUKAN KE [table] CARI "term" | SEARCH [table] "term" | | Grant Permission | BERI IZIN [action] KEPADA [user] DI [table] | GRANT [action] ON [table] TO [user] | | Revoke Permission | CABUT IZIN [action] DARI [user] DI [table] | REVOKE [action] ON [table] FROM [user] |
