Effective Axios Error Logging for Robust SAP IntegrationsEffective Axios Error Logging for Robust SAP IntegrationsTwo logged failures printed side by side, and the point is made by looking at them: one tells you what went wrong and one does not. Axios buries the useful part of an HTTP error, and this is what to unwrap before logging it from a CAP service.Sahil2508, published 2025-08-31

Federated Machine Learning with SAP DatasphereFederated Machine Learning with SAP DatasphereSAP's design for training predictive models on an external machine learning platform against SAP Datasphere data that is not replicated to that platform. The open-source FedML Python library runs in the platform's notebook, connects to Datasphere over Python/SQLDBC and reads the analytic models in which Datasphere unifies SAP and non-SAP sources; a trained model can then be deployed to SAP AI Core, or in several sub-pages to SAP BTP, Kyma runtime, which is the predictive models path where training happens outside SAP. Sub-pages cover Amazon SageMaker, Azure Machine Learning, Google Vertex AI, Databricks, NVIDIA RAPIDS on GPUs and IBM watsonx.published 2025-01-23

Boosting performance in SAP Cloud Application Programming Model (CAP) applications with cds-cachingBoosting performance in SAP Cloud Application Programming Model (CAP) applications with cds-cachingThe plugin's introduction post: what cds-caching is for, how it is put together and the cases it was written against. The edge holds because the plugin's README still points here as the piece to read first, so this is where a reader arriving at the plugin is sent. It predates version 1.0 and the API has moved since: the read-through calls it shows as cache.run() and cache.send() are the ones the README now lists as deprecated in favour of cache.rt.*, which returns the cache key and hit/miss metadata alongside the result, and 1.0 made user, tenant and locale awareness opt-in under keyManagement rather than folding them into request-based keys by default. Metrics and monitoring, the OData API and full TypeScript definitions arrived with 1.0 and are described in CAP just got faster: What's new in cds-caching 1.0 instead. The reasoning about when a CAP service wants a cache still reads true; the call sites need translating.published 2025-06-25

CAP just got faster: What's new in cds-caching 1.0CAP just got faster: What's new in cds-caching 1.0What changed in cds-caching at 1.0, announced at reCAP 2025 by the plugin's own maintainer. The substantive change is the read-through API: cache.rt.run(), send(), exec() and wrap() replace the bare cache.run() and cache.send(), and each returns the cache key and hit-or-miss metadata beside the result rather than the value alone. The second is quieter and easier to miss on an upgrade: user, tenant and locale stopped being folded into request-based cache keys by default and became opt-in through keyManagement, or per operation through a key template. Both of those still describe 3.x. What does not is the second half of the post: the metrics configuration it shows was reshaped at 2.0 and the statistics and dashboard settings were removed at 3.0, so take the monitoring and dashboard sections from the README instead. Read it as the successor to the introduction post, which still shows the deprecated calls.published 2025-07-15
