Spark over Hadoop is a common approach to processing large-scale data efficiently. Apache Spark is a fast and general-purpose cluster computing system for big data processing. It can run on top of the Hadoop Distributed File System (HDFS) and other distributed storage systems. You can achieve faster data processing than traditional Hadoop MapReduce jobs by utilizing Spark’s in-memory processing capabilities.

Spark provides a higher-level API and supports multiple languages, including Scala, Java, Python, and R. It includes libraries for SQL queries, machine learning, graph processing, and streaming data. Spark can be great for tasks like ETL (Extract, Transform, Load), data analysis, and machine learning.

To ensure your emails don’t go to spam when sending out bulk emails related to course information, consider the following best practices:

  1. Use a Reputable Email Service Provider (ESP): Choose a well-known email service provider with a good reputation for delivering legitimate emails and preventing spam.
  2. Authentication: Implement Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) to authenticate your emails and establish trust.
  3. Clean and Targeted Lists: Ensure your email list is clean and up-to-date. Remove invalid or inactive email addresses to improve deliverability.
  4. Avoid Spam Triggers: Craft your email content carefully. Avoid using spam trigger words and excessive use of capital letters, symbols, or exclamation points in the subject line and body.
  5. Personalization: Personalize your emails with recipient names and relevant course information. This can help improve engagement and reduce the likelihood of being marked as spam.
  6. Opt-In and Opt-Out: Ensure you have obtained explicit consent from recipients to send them emails. Provide a straightforward way for recipients to unsubscribe from their emails.
  7. Segmentation: Segment your email list based on recipient preferences and interests. Sending relevant content to specific segments can reduce the chances of your emails being marked as spam.
  8. Testing: Send test emails to different email providers to check if they are being delivered to the inbox or marked as spam. Make adjustments based on the results.
  9. Monitor Deliverability: Keep track of your email deliverability rates and monitor for any issues. Address any problems promptly.
  10. Feedback Loops: Pay attention to feedback loops provided by email service providers. These can help you identify recipients marking your emails as spam and take appropriate action.
