In this video I want to talk over the active active active vs active passive cluster configuration for high availability. We will also explain the pros & cons of using an active-active cluster vs using an active-passive cluster.

A sidecar proxy is an application design pattern which abstracts certain networking features, such as inter-service communications, monitoring and security, timeouts, retries, communication protocols, away from the main architecture to ease the maintenance of the application as a whole.

In this video I’d like to talk about how we classically do things:

Examples

Pros

Sidecar: 7:40

Example: 13:00 (https://www.youtube.com/watch?v=cp3Ku1XeOn8)

MySQL 8.0 supports atomic Data Definition Language (DDL) statements. This feature is referred to as atomic DDL. An atomic DDL statement combines the data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single, atomic transaction. The transaction is either committed, with applicable changes persisted to the data dictionary, storage engine, and binary log, or is rolled back, even if the server halts during the operation.

I discuss mySQL 8.0 atomic ddl compared to Postgres transactional ddl

gRPC (gRPC Remote Procedure Calls[1]) is an open source remote procedure call (RPC) system initially developed at Google in 2015[2]. It uses HTTP/2 for transport, Protocol Buffers as the message format.
