There are several open source CDC projects, often using the same underlying libraries, database APIs, and protocols. No locks on tables are ever acquired, which prevent impacting write traffic on the source database. Hence, downstream consumers receive change events as they occur on a source.

Redis's microsecond latency has made it a de facto choice for caching. Four years ago, as part of our AWS fast data journey, we introduced Amazon ElastiCache for Redis , a fully managed, in-memory data store that operates at microsecond latency. TB of in-memory capacity in a single cluster.

In the MySQL open source ecosystem, we have only two consolidated ways to perform sharding — Vitess and ProxySQL. One example could be using an RDBMS for most of the Online transaction processing ( OLTP) data shared by country and having the products as distributed memory cache with a different technology.

Also, we will take a look at our open-source backup utility custom-built to help avoid costs and proprietary software – Percona Backup for MongoDB or PBM. Especially if going into or out of storage types that may throttle bandwidth/network traffic. Hence, the node would still be available for other operations.

You should expect one-time implementation cost (depending CMS and business requirements it can cost 200,000 USD to 3M USD) and yearly hosting infrastructure cost (proportional to load and traffic but typically 30,000 USD - 300,000 USD per year). In addition, open source CMS solutions also struggle with blotted plugin ecosystem.

The CFQ works well for many general use cases but lacks latency guarantees. The deadline excels at latency-sensitive use cases ( like databases ), and noop is closer to no schedule at all. Make sure the drives are mounted with noatime and also if the drives are behind a RAID controller with appropriate battery-backed cache.

This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. Finally, not inlining resources has an added latency cost because the file needs to be requested. Support is unclear at this time.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
