Everything in the atlas

The generated files are copied or deployed into the ABAP system by hand, the fourth step of its own usage list, so nothing keeps an activated service in step with the model it was generated from. Its peer dependency is `@sap/cds` ^9.8, so it does not install into a project on an earlier CAP release.

Alerting by mail is not telemetry — if you need traces and metrics correlated across handlers, that is a different layer. It also publishes no repository, so the package is the only thing to read.

The project states that until v1.0.0 is reached, breaking changes may occur without prior notice. Rule items do not chain: every rule operates on the original input string, so a format whose second step needs the result of the first needs a custom logic class. A REPLACE rule whose replacement produces the exact same string as the input is reported as `no match`, which the documentation records as a known limitation.

If document versions are required, [@cap-js/sdm](artifact:cap-js-sdm) excludes versioned repositories in its [documented restrictions](https://raw.githubusercontent.com/cap-js/sdm/ad13b61f21816ebead2d08264a74521cfb75846c/README.md).

Not an end-user app: it reads from any table the user names and writes into tables of the Z/Y namespace, with no authorisation check of its own, so the README asks a project to add its own checks on `S_TABU_DIS`/`S_TABU_NAM` and to restrict who may run it before it is used beyond a development system. XLSX upload and download are not ready for ABAP Cloud yet, and of the upload apps only the JSON one writes the file's rows back to the database.

The maintainer marks this early development; expect the contract to move.

When user-dependent responses are cached without user-aware or explicit operation keys, or translated responses share keys across locales. These cases require key isolation; locale-aware keys are off by default.

When your adoption policy excludes experimental dependencies: the [maintainer’s README](https://github.com/cap-js/cds-federation-synonyms#about-this-project) explicitly labels this plugin experimental.

Not on the [SAP BTP ABAP environment](artifact:btp-abap-environment) or another cloud ABAP system: the maintainer states the tool is not cloud ready, because the data sources and system tables it reads CDS metadata from are not released for cloud development. It is designed for SAP S/4HANA on-premise or private cloud, and the shipped Fiori application is configured for A4H and developer systems.

For deployed environments, the [README](https://raw.githubusercontent.com/cap-java/cds-feature-attachments/302f61c8bb76a0f54f43482ad91d89bf7dc5540f/README.md) excludes the cds-feature-attachments-fs file-system target, which is intended only for local development and testing.

If document versions are required, the [documented restrictions](https://raw.githubusercontent.com/cap-java/sdm/673769f24ef66fd97daa6a6be41262d45065d3fe/README.md) exclude versioned repositories.

DataZoo GmbH calls the extension experimental and states that minimal testing and benchmarking were done. The Business Source License 1.1 it carries restricts offering the software to third parties on a hosted or embedded basis, so an embedding product needs a commercial licence. Telemetry is on by default and is switched off per session with `SET erpl_telemetry_enabled = false` or for the machine with `DATAZOO_DISABLE_TELEMETRY=1`.

Its own feature comparison marks connection pooling, automatic reconnect, active-active reads, client-side data encryption, statement distribution, Kerberos authentication, the hdbuserstore, promises and TypeScript types as [@sap/hana-client](https://www.npmjs.com/package/@sap/hana-client) only, so a service that wants a pool or a promise API writes both itself over a callback interface. OpenSSL is its one security provider where the other driver lists SAP CommonCryptoLib, OpenSSL and MSCrypto, and it runs on Node.js 18 or later.

Where the release and programming model offer durable locks, as RAP draft handling does, the README states that those solve the problem at the kernel level and the lock manager is for where that is not an option. A running handler occupies one background work process for as long as any lock is held, and only generated `ENQUEUE_*` modules can be locked.

Neither the package manifest nor the repository tree declares a licence.

Not for a table whose contents matter, and not for one chosen at run time: the name of the table is fixed in the calling code, and the maintainer's own warning is "only hardcode the table name, don't use with important tables, use at own risk!"

The app writes to whatever table is passed in the URL parameter `table` and carries no authorisation check of its own, so past a development system it needs authorisation checks added and a restriction on who may run it.

If you need sub-second fan-out to external consumers this is the wrong layer — reach for [Event Mesh](artifact:btp-event-mesh) or Kafka. Without [Redis](external:redis), periodic processing still works but instant dispatch degrades to polling.

Node below 22, or [@sap/cds](artifact:sap-cds) below 9: the package declares the first in engines and the second as a peer dependency. Any mail path other than Microsoft Graph, until a provider is written for it: graph is the only kind that sends, and basic, the kind configured by default, is the base class such a provider extends.

Reach for the original unless you know why you are not. This is a republished copy rather than a fork with a direction of its own: the README points at cap-js/notifications for the details, and nothing here says what was changed or why.

Input arrives only as JSON, or as plain XML if the ABAP built-in transformation is switched on, whatever the output format is set to. Cross-site calls are limited to JSONP: the maintainer lists CORS support as planned.

Design-time only: no message monitoring, no deployment, no runtime status. That is a different server in this same section, and the two do not overlap.

BUSL-1.1 rather than node-rfc's Apache-2.0, so a product you distribute has to be read against the licence and its Additional Use Grant first, and the source is closed: the GitHub repository is the issue tracker and the documentation, nothing else. `RfcServerOptions.bgRfcHandlers` raises instead of accepting handlers, so a server receiving inbound bgRFC units is outside what this does. An ABAP `MESSAGE`-raised failure still arrives with its T100 template rather than the rendered sentence, and the dump name is not reported as `key` for that case.

It deploys and undeploys, and it enumerates credentials, keystores and OAuth2 configurations. Listing security material is a read, and it is still a read of the thing that protects everything else the tenant talks to.

The maintainer states 0.x is beta with no production SLA, and scopes support deliberately narrowly: direct application-server transport, classic serialization and password authentication on S/4HANA 2023 and NetWeaver 7.50. Anything outside that is untested rather than unsupported.

For an app that calls `client->set_session_stateful( )`, which needs the ICF session of the system it runs on; apps keeping their state in the draft table, the abap2UI5 default, work unchanged. For an app that reads a request header through the user exit on the source system, because the consumer forwards method, body, path, query string and status, not headers.

Inspection only, and it takes a host, a user and a password from the environment rather than a managed credential. PI and PO are also on their own end-of-maintenance path, which is the context any investment here sits in.
