STREAM-Intelligence · USB4SAP · Focused Comparison
USB4SAP vs IBM Event Streams, Confluent, asapio, and Advantco — real-time streaming from SAP evaluated across 22 parameters. Architecture, SAP alignment, semantic readiness, and AI fit. April 2026.
Scope of this comparison. All five tools are positioned as real-time SAP data streaming solutions. The key architectural divide: IBM Event Streams and Confluent are Kafka-based event brokers that require a separate SAP connector layer to source data. asapio and Advantco are SAP-specialist connectors that can publish SAP events to Kafka or cloud targets. USB4SAP is a zero-copy streaming REST API — no broker, no connector chain, no pipeline. This table evaluates what each delivers natively when streaming SAP data, without third-party add-ons, and how each aligns to SAP's clean-core, RISE, and zero-copy standards.

|---|---|---|---|---|---|
| Architecture & Streaming Model | |||||
| Core streaming architecture How the tool streams SAP data | Zero-copy REST streaming API No broker. No connector chain. Live SAP data per REST request or CDC push. No pipeline required. | Kafka event broker Receives SAP events from a separate connector layer (Kafka Connect + SAP source connector). IBM does not source SAP data natively. | Kafka platform + Kafka Connect SAP data sourced via third-party Kafka Connect connectors (e.g., Lenses, custom RFC/IDOC connectors). Confluent itself is not an SAP connector. | SAP-native event publisher Connects to SAP via application layer; publishes events to Kafka, Azure Event Hub, or other brokers. SAP specialist — broker is a target, not built-in. | SAP-certified integration adapter Adapters for SAP → Kafka, MQ, JMS, cloud targets. Application-layer to SAP; certified for ECC, S/4HANA. |
| Requires a message broker / Kafka cluster Dependency on Kafka or equivalent event bus infrastructure | No No Kafka. No broker. REST API delivers data directly to any consumer or target. | Yes IBM Event Streams is the Kafka broker. Requires Kafka Connect + SAP source connector to ingest SAP data. | Yes Confluent is the Kafka platform. Requires a separate SAP source connector deployed on Kafka Connect workers. | Partial asapio publishes to Kafka or Azure Event Hub; broker is customer-managed. asapio itself is the SAP connector layer. | Partial Advantco adapter publishes to Kafka, MQ, or JMS targets; broker is separate. Adapter is the SAP-side component. |
| End-to-end SAP streaming without third-party connectors Complete solution from SAP source to consumer without additional components | Yes Single product. SAP → REST consumer or target. No connector chain, no broker, no third-party dependency. | No IBM Event Streams + Kafka Connect + SAP source connector required. Multi-component stack. | No Confluent + SAP Kafka Connect connector (third-party) required. Confluent alone cannot read SAP. | Yes asapio covers the SAP-to-broker path natively; combined with customer's broker it is end-to-end. | Yes Advantco adapter covers SAP-to-target natively; broker or target is customer-managed. |
| Streaming latency Time from SAP change to consumer availability | 0.143s CDC delta Benchmarked on 100M+ row table. Co-validated with Microsoft. On-demand live query is synchronous. | Seconds to minutes Kafka consumer latency is low once data is in topic; SAP-to-Kafka connector polling interval adds seconds to minutes depending on config. | Seconds to minutes Kafka connector polling interval determines SAP lag. Confluent cloud broker itself has sub-second topic-to-consumer latency once data is ingested. | Near real-time Event-driven via SAP Business Events / IDocs / BAPIs; latency depends on SAP event trigger and broker delivery. Typically seconds. | Near real-time Application-layer polling or event-triggered; latency in seconds depending on SAP object and adapter configuration. |
| SAP Strategic Alignment | |||||
| SAP clean-core aligned No custom ABAP, no modification of SAP core | Yes No ABAP. No custom dev. SAP Note 3255746 compliant. SAP NetWeaver certified. | N/A IBM Event Streams has no SAP-side footprint. Clean-core compliance depends entirely on the SAP connector chosen. | N/A Confluent has no SAP-side component. Clean-core compliance depends on the Kafka Connect SAP source connector used. | Yes Application-layer approach; uses standard SAP APIs (BAPIs, IDocs, Business Events); no ABAP modifications. | Partial SAP-certified adapters; some configurations may require ABAP transports; ECC adapters vary by release. |
| SAP RISE Public Cloud compatible Works without DB-level access or Z-table writes on RISE | Yes No DB access. No Z-tables. Fully RISE Public Cloud compatible. | N/A RISE compatibility depends on the SAP source connector deployed with Kafka Connect, not IBM Event Streams itself. | N/A RISE compatibility depends on which Kafka Connect SAP connector is used. RFC-based connectors may be blocked on RISE Public Cloud. | Yes Application-layer via standard SAP APIs; compatible with RISE Public Cloud constraints. | Partial RISE Public Cloud compatibility varies by adapter and SAP release; direct DB or RFC path may be restricted. |
| SAP zero-copy aligned Data never copied outside SAP security boundary | Yes Only vendor aligned to SAP zero-copy. Data queried live at source, not replicated through an intermediary. | No Data is extracted from SAP, staged in Kafka topics. Multiple copies exist in the pipeline. | No Data extracted from SAP, published to Kafka topics in Confluent cloud or on-premise cluster. Copy exists outside SAP. | No Events published out of SAP to broker; data leaves SAP boundary on publish. | No Data pushed from SAP to target; copy exists outside SAP once delivered. |
| SAP Object Coverage & CDC | |||||
| SAP table CDC (without SLT) Change capture on any SAP table without Landscape Transformation Server | Yes Timeseries & Doc# series CDC. 850K+ tables. No SLT. No change pointers. 0.143s on 100M+ rows. | Partial Depends on Kafka Connect SAP connector used. RFC/JDBC-based connectors may support table polling; true CDC without SLT is connector-dependent. | Partial Confluent SAP connector options vary. Log-based CDC requires direct DB access (blocked on RISE). Application-layer polling is connector-dependent. | Partial Focuses on SAP Business Events, IDocs, BAPIs — event-driven objects. Raw table CDC requires additional configuration; not primary use case. | Partial Table streaming supported via RFC/BAPI layer; SLT may be needed for large-table CDC; delete detection varies. |
| SAP Business Events / IDocs / BAPIs Event-driven SAP objects — order created, GR posted, etc. | Yes All SAP RFC/BAPI objects accessible. On-demand or CDC. Full object scope including custom Z-objects. | Partial IDocs and BAPIs accessible via Kafka Connect SAP connector; native SAP Business Events require connector support. | Partial IDoc streaming via Kafka Connect SAP connectors available on Confluent Hub; event scope is connector-dependent. | Yes Primary use case: SAP Business Events, IDocs, BAPIs published to Kafka/Event Hub. Deep SAP event integration. | Yes IDocs, BAPIs, RFCs — core adapter capability. Event-driven and polling modes. |
| CDS Views & ODP DataSources Semantic SAP extraction objects | Yes 450K+ semantic models including CDS views, BW DataSources, BEx queries. | Partial CDS via OData/ODP accessible through appropriate Kafka Connect SAP connector; not native to IBM Event Streams. | Partial CDS/ODP access is connector-dependent. Some Confluent Hub connectors support OData-based CDS extraction. | Partial ODP/CDS access available; primary strength is business event streaming, not analytical CDS model delivery. | Partial OData and RFC-based CDS access available; analytical model delivery not primary focus. |
| Delete detection in streaming Hard-deleted SAP records captured in the stream | Yes Field-level CDC detects inserts, updates, and deletes natively. No additional configuration. | Partial Delete capture depends on the Kafka Connect SAP source connector. Log-based connectors may detect deletes; polling-based may not. | Partial Connector-dependent. Confluent's Debezium-style connectors detect deletes at DB level; SAP application-layer connectors may not. | Partial SAP soft-delete flags captured via business events; hard-delete detection depends on SAP object and configuration. | Partial Adapter-dependent; logical delete flags captured; hard-delete detection requires specific configuration. |
| Total SAP objects streamable Breadth of SAP objects accessible for streaming | 1.9M+ objects 850K+ tables · 450K+ semantic models · Reports, TCODEs, ALV, Z-objects. All via REST. | Partial Object scope determined by the SAP Kafka connector deployed. IBM Event Streams itself imposes no limit — but also provides no SAP access. | Partial Connector-dependent. Confluent Hub connectors typically cover IDocs, BAPIs, OData — not full table breadth. | Partial Strong on SAP event objects (IDocs, BAPIs, Business Events); narrower on raw table and report scope. | Partial IDocs, BAPIs, RFCs, OData — solid coverage of transactional events; full table/report scope not primary capability. |
| Semantic Intelligence & Business Readiness | |||||
| Pre-built SAP semantic models Business-named objects (Purchase Order) not raw tables (EKKO/EKPO) | Yes 450K+ pre-built semantic models. Data arrives business-named. No downstream reverse-engineering. | No Kafka topics receive raw SAP payloads (IDoc XML, table rows). Semantic layer must be built downstream by the consumer. | No Confluent streams raw SAP event payloads. Schema Registry (Avro/Protobuf) adds structure but not SAP business semantics. | Partial Business events carry SAP object context (e.g., SalesOrder.Created); payload is SAP-structured but not a curated semantic catalog. | Partial IDoc and BAPI payloads carry business object context; no pre-built semantic catalog — consumer must interpret SAP payload structure. |
| Schema management for SAP payloads Automatic schema versioning and evolution as SAP objects change | Yes Schema-on-read. SAP metadata surfaced per request. Business and technical field names always included. | Yes Confluent Schema Registry integration available; Avro/JSON Schema/Protobuf. SAP schema changes must be handled by connector and registry. | Yes Confluent Schema Registry is a core capability. SAP payload schemas registered and versioned; evolution rules enforced. | Partial Schema mapping from SAP to target format; versioning depends on broker (Kafka Schema Registry if Kafka is target). | Partial Adapter handles IDoc/BAPI structure; schema evolution managed via SAP release updates to adapter configuration. |
| Semantic streaming to Microsoft Fabric / OneLake Business-named models delivered to Fabric, not raw event payloads | Yes Microsoft-certified. 450K+ semantic models provisioned into OneLake. Business-ready on arrival. | Partial IBM Event Streams → Kafka Connect → Fabric via Event Hub or ADLS. Raw topic data lands in Fabric; semantic layer is a downstream task. | Partial Confluent → Azure Event Hub → Fabric pipeline possible; raw Kafka topic data lands, not business-named models. | Partial asapio can target Azure Event Hub or ADLS; Fabric delivery possible but semantic translation at landing is customer responsibility. | Partial Advantco can publish to Azure targets; semantic readiness at Fabric landing is not delivered out-of-box. |
| Security & Data Sovereignty | |||||
| SAP native authorizations enforced at streaming layer SAP roles govern what data enters the stream — no shadow security build | Yes 100% native SAP application authorizations. Role changes reflect immediately. No copy outside auth model. | No Once data is in a Kafka topic, SAP authorization model is lost. Topic-level ACLs replace SAP role-based security. | No Confluent RBAC applies at the Kafka layer. SAP role model is not propagated to topic consumers. Separate security layer required. | Partial SAP auth enforced at extraction; once event is published to broker, downstream security is broker-governed, not SAP-governed. | Partial SAP credentials used at extraction; adapter enforces SAP auth at source; downstream consumers use broker security. |
| Data sovereignty — no vendor infrastructure in data path SAP data does not transit vendor-managed cloud infrastructure | Yes STREAM Activate: data never leaves your environment. No external pipeline. Full sovereignty. | Partial IBM Event Streams on-premise (via OpenShift) keeps data in customer environment. IBM Cloud deployment routes data through IBM infrastructure. | Partial Confluent Cloud routes data through Confluent-managed infrastructure. Self-managed Confluent Platform keeps data on-premise. | Yes asapio runs in customer environment; data published directly to customer-managed broker. No asapio cloud in data path. | Yes Advantco adapter runs on customer SAP system; data delivered to customer-managed target. No vendor cloud in data path. |
| Deployment & Target Platforms | |||||
| Microsoft Fabric / Azure Event Hub Native delivery to Microsoft streaming and analytics targets | Yes Microsoft-certified. ADLS, OneLake, Fabric, Power BI, Excel, API-M. Azure Marketplace published. | Partial IBM Event Streams can mirror to Azure Event Hub via Kafka MirrorMaker 2 or Kafka Connect sink; not native Fabric integration. | Yes Confluent → Azure Event Hub (Kafka-compatible endpoint) is a supported path; Fabric integration via Event Hub or Kafka connector. | Yes Azure Event Hub is a primary asapio target; SAP events published to Event Hub for downstream Fabric consumption. | Partial Azure Event Hub and ADLS targets supported; Fabric-specific integration not confirmed as native capability. |
| AWS Kinesis / MSK / GCP Pub/Sub / Databricks Multi-cloud streaming and analytics targets | Yes REST API works with any target. AWS, GCP, Databricks, Snowflake — no vendor lock-in. | Yes IBM Event Streams (Kafka) integrates with Kinesis, MSK, Pub/Sub via Kafka Connect sinks and MirrorMaker. | Yes Confluent fully multi-cloud; native connectors for Kinesis, MSK, Pub/Sub, Databricks Delta Lake, Snowflake. | Partial Kafka and Azure Event Hub primary targets; other cloud streaming targets via broker bridge. | Partial MQ, JMS, Kafka primary targets; multi-cloud streaming target coverage varies by adapter edition. |
| On-premise or air-gapped deployment Deployable without internet egress from SAP environment | Yes STREAM Activate runs fully on-premise. No cloud dependency. Proven in air-gapped environments (Tata Power). | Yes IBM Event Streams on OpenShift supports fully on-premise deployment. | Yes Confluent Platform (self-managed) supports on-premise deployment. Confluent Cloud requires internet connectivity. | Yes asapio deployed in customer SAP environment; on-premise compatible. | Yes Adapter deployed on SAP system; on-premise deployment supported. |
| No-Code & AI Readiness | |||||
| Live REST API for SAP data — no consumer SDK required Any app queries live SAP data via REST without Kafka client, JCo, or ABAP | Yes 1.3M+ SAP objects as no-code REST API. No Kafka client. No SAP SDK. Works with any REST consumer including low-code tools. | No Consumers require Kafka client libraries. IBM Event Streams REST Proxy available but adds latency; not a live SAP query API. | Partial Confluent REST Proxy and HTTP Sink connector allow REST access to Kafka topics; not a live SAP query — consumers read from topic, not live SAP. | No asapio publishes events to broker; consumer must use broker's client (Kafka, Event Hub SDK). No direct REST-to-SAP query path. | No Adapter delivers to target (Kafka, MQ); consumers use target's protocol. No direct REST-to-SAP live query. |
| AI agent ready (MCP / live SAP context per inference) AI agents can query live SAP data per request without broker dependency | Yes MCP catalog for AI agents. Live SAP data per agent request. Verifiable-at-source AI. P2P Agent autonomous since Nov 2023. | No Kafka topics are not suitable for per-inference live SAP queries. Agents would read stale topic data, not live SAP state. | No Confluent streams are not a live SAP query API. AI agents reading Kafka topics get the latest event, not a live SAP query result. | No Event streaming model; agents receive events as published, not live on-demand SAP queries. | No Event/message delivery model; not designed for per-inference live SAP data queries by AI agents. |
| No-code configuration — zero SAP ABAP work per stream New SAP data stream activated without SAP developer involvement | Yes No CDS creation. No ABAP. No annotations. Any of 1.9M+ objects streamable on-demand via UI or API. | No New SAP objects require connector reconfiguration or new Kafka Connect task. SAP developer needed to expose new objects through the connector. | No Adding new SAP sources requires connector configuration and potentially SAP-side prep (OData annotation, RFC exposure). Not zero-code. | Partial Event configuration is largely no-code for supported SAP event types; custom events may require SAP Business Events configuration. | Partial Adapter configuration is UI-based for supported objects; custom objects may require ABAP or adapter extension work. |
| Primary use case fit | Live SAP API for analytics, AI agents, automation & semantic streaming — no broker, no pipeline, no copy | Enterprise Kafka event broker for high-throughput event streaming; SAP sourcing requires a separate connector layer | Kafka platform with rich connector ecosystem; SAP sourcing via third-party Kafka Connect connectors; strong schema management | SAP-native event publishing to Kafka / Azure Event Hub; deep SAP Business Events, IDoc, and BAPI integration | SAP-certified adapter for IDoc, BAPI, RFC streaming to Kafka, MQ, and JMS targets; transactional event focus |
