PRICE TRACKING MIGRATION SCRIPT
|
|
========================================
|
|
|
|
This script will migrate lastPriceUpdate and lastPriceDate fields
|
|
from eodSymbols collection to the operations tracking system.
|
|
|
|
To run this migration:
|
|
|
|
1. Update the MONGODB_URI in this file with your MongoDB credentials
|
|
OR set the MONGODB_URI environment variable
|
|
|
|
2. Run the script:
|
|
node run-price-migration.js
|
|
|
|
The script will:
|
|
- Find all documents with lastPriceUpdate field
|
|
- Convert dates to normalized format (00:00:00 UTC)
|
|
- Create operations.price_update structure
|
|
- Process in batches of 1000 documents
|
|
|
|
Total documents to migrate: ~199,175
|
|
|
|
Migration query that will be executed:

console.log(`
|
|
db.eodSymbols.find({
|
|
lastPriceUpdate: { $exists: true },
|
|
'operations.price_update': { $exists: false }
|
|
}).forEach(doc => {
|
|
const normalizedDate = new Date(doc.lastPriceUpdate);
|
|
normalizedDate.setUTCHours(0, 0, 0, 0);
|
|
|
|
let lastRecordDate = null;
|
|
if (doc.lastPriceDate) {
|
|
try {
|
|
lastRecordDate = new Date(doc.lastPriceDate);
|
|
} catch (e) {}
|
|
}
|
|
|
|
db.eodSymbols.updateOne(
|
|
{ _id: doc._id },
|
|
{
|
|
$set: {
|
|
'operations.price_update': {
|
|
lastRunAt: normalizedDate,
|
|
lastSuccessAt: normalizedDate,
|
|
status: 'success',
|
|
...(lastRecordDate && { lastRecordDate })
|
|
}
|
|
}
|
|
}
|
|
);
|
|
});
|
|
`);
|
|
|
|
console.log(`
|
|
After migration, you can optionally remove old fields:
|
|
db.eodSymbols.updateMany({}, { $unset: { lastPriceUpdate: '', lastPriceDate: '' } })
|
|
|
|
To verify migration:
|
|
db.eodSymbols.findOne({ 'operations.price_update': { $exists: true } })
|
|
`);
|
|
}
|
|
|
|
runMigration(); |
