Just curious about your just curious; what is the architecture of the current Tumblr back end?

This appears to be 6 years old. Is it still relevant?

Ehhh parts of that article were never accurate, especially the stuff about having an hbase-powered dashboard feed.

Primarily the product backend is monolithic PHP (custom framework) + services in various languages + sharded MySQL + Memcached + Gearman. Lots of other technologies in use though too, but I'll defer to current employees if they want to answer.

Fantasy big data: let's use Hadoop and Kafka!

Reality big data: Let's shard it across Mysql.

You’re being generous. Most of that article was a pipe dream that never came to fruition.

That's a really underrated statement - as a lot of "scale blogs" are often referred to as fact. I'll have to reconsider a lot of those in hindsight.

Cool, thanks for the answer.
