UPM is our internal standalone library to perform static analysis of SQL code and enhance SQL authoring. UPM takes SQL code as input and represents it as a data structure called a semantic tree. Infrastructure teams at Meta leverage UPM to build SQL linters, catch user mistakes in SQL code, and perform data lineage analysis [...] Read More...

We developed a new static analysis tool called Nullsafe that is used at Meta to detect NullPointerException (NPE) errors in Java code. Interoperability with legacy code and gradual deployment model were key to Nullsafe’s wide adoption and allowed us to recover some null-safety properties in the context of an otherwise null-unsafe language in a multimillion-line [...] Read More...

Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (NTP), provided us with millisecond precision, but as we scale to more advanced systems on our way to building the next computing platform, the metaverse and AI, [...] Read More...

We’re sharing Tulip, a binary serialization protocol supporting schema evolution.  Tulip assists with data schematization by addressing protocol reliability and other issues simultaneously.  It replaces multiple legacy formats used in Meta’s data platform and has achieved significant performance and efficiency gains. There are numerous heterogeneous services, such as warehouse data storage and various real-time systems, [...] Read More...

In our constant quest to prioritize efficiency, Instagram’s engineers have developed a way to process new videos that reduces the cost to produce basic video encodings by 94 percent. With this method in place, Meta’s video infrastructure can continue to scale without needing to add more machines. This frees up resources so more people can [...] Read More...
