They allow the definition of “interfaces for types”, where values of types which conform to that specification can be freely swapped out. reading and writing to a byte stream). classmethod def decode ( cls , data : bytes ) - > Self : # Implementation goes here. traits” in Rust and “concepts” in C++20). write ( obj.

A guide to UDP in Scala with FS2

Rock the JVM

The UDP header is fixed at 8 bytes and contains a source port, destination port, the checksum used to verify packet integrity by the receiving device, and the length of the packet which equates to the sum of the payload and header. flip () println ( s "[server] I've received ${content.limit()} bytes " + s "from ${clientAddress.toString()}!

Tulip: Modernizing Meta’s data platform

Engineering at Meta

Chart 2: Bytes logged per second via Legacy versus Tulip. We can see that while the number of logging schemas remained roughly the same (or saw some organic growth), the bytes logged saw a significant decrease due to the change in serialization format. Reader (like logger) comes in two flavors , (a) code generated and (b) generic.

Improving Efficiency Of Goku Time Series Database at Pinterest (Part?—?1)

Pinterest Engineering

See the graph below, which shows the compaction read and write bytes on a cluster when it is bootstrapping for the first time. Figure 10: compaction read and write bytes showing non zero values as soon as host starts up. This slow bootstrap time was a definite hindrance on our move to less compute heavy instances for cost savings.

Lyft Engineering

Instead, we chose to use an envoy circuitbreaker , which returns an HTTP 503 code immediately to the downstream caller. This should definitely help bring down the downtime further given that all of the steps for replication, cutting the traffic over to the upgraded DB, and the rollback setup would be handled within their platform.

Deploying Kafka Streams and KSQL with Gradle – Part 2: Managing KSQL Implementations

Confluent

We’ll demonstrate using Gradle to execute and test our KSQL streaming code, as well as building and deploying our KSQL applications in a continuous fashion. In this way, registration queries are more like regular data definition language (DDL) statements in traditional relational databases. Managing KSQL dependencies.

Practical API Design at Netflix, Part 1: Using Protobuf FieldMask

Netflix Tech

By default, gRPC uses protobuf as its IDL (interface definition language) and data serialization protocol. Our protobuf message definition (.proto link] When the protobuf compiler (protoc) compiles this message definition, it creates the code in the language of your choice (Java in our example).
