HANA Database Migration: Handling Incompatible Changes to Existing TablesHANA Database Migration: Handling Incompatible Changes to Existing TablesThe question schema evolution exists for, asked plainly: how do you restructure a table in a production system that already holds live data. Incompatible changes are the ones CAP's own alter path will not make, which is where this starts.Sekar Somasundaram, published 2025-04-16

Introducing eslint-plugin-better-cap-config an ESLint plugin to improve CAP configurationIntroducing eslint-plugin-better-cap-config an ESLint plugin to improve CAP configurationThe author's own announcement, and precise about scope: today it catches deprecated key/value entries in CAP's JSON configuration, and the ambition is that it grows into best practices, suggestions and autofixes the way any ESLint plugin does. The implementation detail worth knowing is that it uses modern ESLint's JSON language support rather than a generic parser, which is what makes linting a configuration file rather than source code work at all.published 2025-09-08

Handling CSV Data Deployment in CAP HDI Without Data LossHandling CSV Data Deployment in CAP HDI Without Data LossThe same trap from the HDI side: .hdbtabledata hands the container full ownership of the data, so the next deployment overwrites the table from the file. Two independent posts three months apart on the same sharp edge, which is a fair signal about how sharp it is.Sekar_Somasundaram, published 2025-06-04
