+
+## Overview
+
+The import process extracts data from a MySQL 5.7 production database and imports it into a PostgreSQL database. It can operate in two modes:
+
+- **Full Import**: Imports all data regardless of last sync time
+- **Incremental Import**: Only imports data that has changed since the last import
+
+The process handles four main data types:
+- Categories (product categorization hierarchy)
+- Products (inventory items)
+- Orders (sales records)
+- Purchase Orders (vendor orders)
+
+## Import Architecture
+
+The import process follows these steps:
+
+1. **Establish Connection**: Creates a SSH tunnel to the production server and establishes database connections
+2. **Setup Import History**: Creates a record of the current import operation
+3. **Import Categories**: Processes product categories in hierarchical order
+4. **Import Products**: Processes products with their attributes and category relationships
+5. **Import Orders**: Processes customer orders with line items, taxes, and discounts
+6. **Import Purchase Orders**: Processes vendor purchase orders with line items
+7. **Record Results**: Updates the import history with results
+8. **Close Connections**: Cleans up connections and resources
+
+Each import step uses temporary tables for processing and wraps operations in transactions to ensure data consistency.
+
+## Column Mappings
+
+### Categories
+| PostgreSQL Column | MySQL Source                    | Transformation                               |
+|-------------------|---------------------------------|----------------------------------------------|
+| cat_id            | product_categories.cat_id       | Direct mapping                               |
+| name              | product_categories.name         | Direct mapping                               |
+| type              | product_categories.type         | Direct mapping                               |
+| parent_id         | product_categories.master_cat_id| NULL for top-level categories (types 10, 20) |
+| description       | product_categories.combined_name| Direct mapping                               |
+| status            | N/A                             | Hard-coded 'active'                          |
+| created_at        | N/A                             | Current timestamp                            |
+| updated_at        | N/A                             | Current timestamp                            |
+
+**Notes:**
+- Categories are processed in hierarchical order by type: [10, 20, 11, 21, 12, 13]
+- Type 10/20 are top-level categories with no parent
+- Types 11/21/12/13 are child categories that reference parent categories

+
+**Notes:**
+- Replenishable calculation: 
+  ```javascript
+  CASE 
+    WHEN p.reorder < 0 THEN 0
+    WHEN (
+      (COALESCE(pls.date_sold, '0000-00-00') = '0000-00-00' OR pls.date_sold <= DATE_SUB(CURRENT_DATE, INTERVAL 5 YEAR))
+      AND (p.datein = '0000-00-00 00:00:00' OR p.datein <= DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 5 YEAR))
+      AND (p.date_refill = '0000-00-00 00:00:00' OR p.date_refill <= DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 5 YEAR))
+    ) THEN 0
+    ELSE 1
+  END
+  ```
+
+In business terms, a product is considered NOT replenishable only if:
+- It was manually flagged as not replenishable (negative reorder value)
+- OR it shows no activity across ALL metrics (no sales AND no receipts AND no refills in the past 5 years)
+- Image URLs are constructed using this pattern:
+  ```javascript
+  const paddedPid = pid.toString().padStart(6, '0');
+  const prefix = paddedPid.slice(0, 3);
+  const basePath = `${imageUrlBase}${prefix}/${pid}`;
+  return {
+    image: `${basePath}-t-${iid}.jpg`,
+    image_175: `${basePath}-175x175-${iid}.jpg`,
+    image_full: `${basePath}-o-${iid}.jpg`
+  };
+  ```

+**Notes:**
+- Only orders with order_status >= 15 and with a valid date_placed are processed
+- For incremental imports, only orders modified since last sync are processed
+- Discount calculation combines three sources:
+  1. Base discount: order_items.prod_price_reg - order_items.prod_price
+  2. Promo discount: SUM of order_discount_items.amount
+  3. Proportional order discount: Calculation based on order subtotal proportion
+  ```javascript
+  (oi.base_discount + 
+   COALESCE(ot.promo_discount, 0) + 
+   CASE 
+    WHEN om.summary_discount > 0 AND om.summary_subtotal > 0 THEN 
+      ROUND((om.summary_discount * (oi.price * oi.quantity)) / NULLIF(om.summary_subtotal, 0), 2)
+    ELSE 0 
+   END)::DECIMAL(10,2)
+  ```
+- Taxes are taken from the latest tax record for an order
+- Cost data is taken from the latest non-pending cost record

+## Special Calculations
+
+### Date Validation
+
+MySQL dates are validated before insertion into PostgreSQL:
+
+```javascript
+function validateDate(mysqlDate) {
+  if (!mysqlDate || mysqlDate === '0000-00-00' || mysqlDate === '0000-00-00 00:00:00') {
+    return null;
+  }
+  // Check if the date is valid
+  const date = new Date(mysqlDate);
+  return isNaN(date.getTime()) ? null : mysqlDate;
+}
+```
+
+### Retry Mechanism
+
+Operations that might fail temporarily are retried with exponential backoff:
+
+```javascript
+async function withRetry(operation, errorMessage) {
+  let lastError;
+  for (let attempt = 1; attempt <= MAX_RETRIES; attempt++) {
+    try {
+      return await operation();
+    } catch (error) {
+      lastError = error;
+      console.error(`${errorMessage} (Attempt ${attempt}/${MAX_RETRIES}):`, error);
+      if (attempt < MAX_RETRIES) {
+        const backoffTime = RETRY_DELAY * Math.pow(2, attempt - 1);
+        await new Promise(resolve => setTimeout(resolve, backoffTime));
+      }
+    }
+  }
+  throw lastError;
+}
+```
+
+### Progress Tracking
+
+Progress is tracked with estimated time remaining:
+
+```javascript
+function estimateRemaining(startTime, current, total) {
+  if (current === 0) return "Calculating...";
+  const elapsedSeconds = (Date.now() - startTime) / 1000;
+  const itemsPerSecond = current / elapsedSeconds;
+  const remainingItems = total - current;
+  const remainingSeconds = remainingItems / itemsPerSecond;
+  return formatElapsedTime(remainingSeconds);
+}
+```
+
+## Implementation Notes
+
+### Transaction Management
+
+All imports use transactions to ensure data consistency:
+
+- **Categories**: Uses savepoints for each category type
+- **Products**: Uses a single transaction for the entire import
+- **Orders**: Uses a single transaction with temporary tables
+- **Purchase Orders**: Uses a single transaction with temporary tables
+
+### Memory Usage Optimization
+
+To minimize memory usage when processing large datasets:
+
+1. Data is processed in batches (100-5000 records per batch)
+2. Temporary tables are used for intermediate data
+3. Some queries use cursors to avoid loading all results at once
+
+### MySQL vs PostgreSQL Compatibility
+
+The scripts handle differences between MySQL and PostgreSQL:
+
+1. MySQL-specific syntax like `USE INDEX` is removed for PostgreSQL
+2. `GROUP_CONCAT` in MySQL becomes string operations in PostgreSQL
+3. Transaction syntax differences are abstracted in the connection wrapper
+4. PostgreSQL's `ON CONFLICT` replaces MySQL's `ON DUPLICATE KEY UPDATE`
+
+### SSH Tunnel
+
+Database connections go through an SSH tunnel for security:
+
+```javascript
+ssh.forwardOut(
+  "127.0.0.1",
+  0,
+  sshConfig.prodDbConfig.host,
+  sshConfig.prodDbConfig.port,
+  async (err, stream) => {
+    if (err) reject(err);
+    resolve({ ssh, stream });
+  }
+);
+```
