Engineering at Meta

FEBRUARY 20, 2024

This new convergence helps Meta and the larger community build data management systems that are unified, more efficient, and composable. Meta’s Data Infrastructure teams have been rethinking how data management systems are designed. An introduction to Velox Velox is the first project in our composable data management system program.

Let me quickly describe where the RocksDB storage nodes fall in the overall system architecture. RocksDB-Cloud replicates all the data and metadata for a RocksDB instance to S3. We limit the number of bytes that can be written per second to all RocksDB instances assigned to a leaf node.

Like a dragon guarding its treasure, each byte stored and each query executed demands its share of gold coins. Join as we journey through the depths of cost optimization, where every byte is a precious coin. It is also possible to set a maximum for the bytes billed for your query.

After content ingestion, inspection and encoding, the packaging step encapsulates encoded video and audio in codec agnostic container formats and provides features such as audio video synchronization, random access and DRM protection. Once all the chunks are encoded, they are physically stitched back into a final encoded bitstream.

One of the key challenges of building an enterprise-class robust scalable storage system is to validate the system under duress and failing system components. This includes, but is not limited to: failed networks, failed or failing disks, arbitrary delays in the network or IO path, network partitions, and unresponsive systems.

Apache Kafka ® is a distributed system. When a client (producer/consumer) starts, it will request metadata about which broker is the leader for a partition—and it can do this from any broker. This is the metadata that’s passed back to clients. The host/IP used must be accessible from the broker machine to others.

For a more concrete example, we are going to write a program that will parse markdown files, extract words identified as tags, and then regenerate those files with tag-related metadata injected back into them. This fits our broad definition above, because the tail isn’t evaluated until accessed - meaning they are made available over the time.

These datasets can represent anything from service configuration to the results of a batch job, are often needed in-memory to optimize access and must be updated as they change over time. Datasets themselves are of varying size, from a few bytes to multiple gigabytes. Each version contains metadata (keys and values) and a data pointer.
