QUESTION
I have the following sequelize code:
...ANSWER
Answered 2020-Aug-09 at 06:41It turns out this SQL query wasn't specific enough and it ended up returning about 1000 rows, so about 50,000 fields. All together, this was approximately 2MB of data being serialized into Javascript objects. My problem is also that the code is overall very OO with lots of domain objects. I think sequelize-transparent-cache caches raw data and not Javascript objects. I ended up writing my own Redis cache which serialized Javascript objects and I got a performance improvement, but I couldn't store the object type, so I still had to do a new object 1000 times. ActiveRecord and the cache mechanism was better at keeping track of the object types during serialization and deserialization. In the end, adding more where clauses to my original SQL query resulted in less records and a big performance increase.
