Perplexity publishes research on CobbleDB, its in-house search database

Perplexity is publishing research on how it built CobbleDB, a key-value database it says serves web content for Perplexity search. The company credits two engineers and hundreds of proactive, always-on AI agents with building the core infrastructure in two months. Aravind Srinivas describes CobbleDB as a replacement for AWS DynamoDB and projects savings of up to $100 million a year from migrating to it.
