Erlang Solutions: Change data capture with Postgres & Elixir
CDC is the process of identifying and capturing data changes from the database.

With CDC, changes to data can be tracked in near real-time, and that information can be used to support a variety of use cases, including auditing, replication, and synchronisation.

A good example of a use case for CDC is to consider an application which inserts a record into the database and pushes an event to a message queue after the record has … ⌘ Read more

Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.

So far I configured most (almost all) settings for GoBlog through a YAML file. But this is not so optimal, after all it happens sometimes that I want to change a small setting, such as the description of a post section, from my smartphone. This would work somehow via SSH, but ideal is something else. Email conversations with Andrés Cárdenas inspired me to finally start the project “settings in the database”. The first step was to make it possible to configure the mentioned post sections. This is now finally possible … ⌘ Read more

The complexity is a feature. It means standards can be replaced with products that let providers get their cut. It means putting data into the slowest most expensive database in cost and enviromnmental impact.

@will@twtxt.net At work we are using KeePass with Multi Cert KeyProvider Plugin.

in particular, twtxt provides timestamps. weewiki doesn’t really track the passage of time. it only wants to be a key/value database with org markup.
