The Challenges & Our Solutions
Large Attachments
Uploading large Base64 files caused Oracle CLOB issues and blocked users.
Chunked Storage
Split files into 2,500-character chunks, store in a table, and reassemble later.
Performance Drop
Large uploads locked Oracle resources, reducing concurrency.
Optimized Inserts
Storing smaller chunks improved efficiency and allowed multiple users to upload simultaneously.
Oracle Downtime
Requests hung if Oracle was unavailable.
Retry Queue
Failed requests moved to RabbitMQ Retry Queue and retried automatically when Oracle returned.
System Responsiveness
Users had no feedback during Oracle outages.
Immediate Acknowledgment
Backend returned “Request queued” immediately while processing retries later.
Key Features
Efficient Large File Handling
Large attachments (images, documents, etc.) are split into manageable 2,500-character chunks, ensuring Oracle can process uploads without performance degradation or blocking.
Optimized System Performance
Chunk-based storage and processing reduce resource locking in Oracle, allowing multiple users to upload and access data concurrently without slowdowns.
Resilient Retry Mechanism
If Oracle is unavailable, requests are automatically moved to a Retry Queue. They are retried seamlessly once Oracle is back online, preventing data loss.
Uninterrupted User Experience
Users receive immediate acknowledgment (e.g., “Request queued”), keeping the system responsive even during outages, while ensuring all requests are eventually processed.
