Flexible Enterprise Architecture
Delivering resilience and scalability for mission-critical data integration requires robust and modular components. SAP BODS provides extensive options to tune and scale across key aspects:
Parallel data flows split huge processing into smaller streams that run simultaneously across multiple job servers. This ensures linear speedup by leveraging more resources.
High availability for critical services like repositories and job servers provided via native synchronization or add-ons. No single point of failure.
Workload isolation reserves dedicated servers, storage and network for ETL compared to sharing with transactional systems. Predictable throughput.
Disaster recovery options to backup key metadata and configurations to remote data centers. Helps recover from outages by relaunching flows quickly.
Containerization through native Kubernetes operators and helm charts simplifies deployment across on-premise and cloud.
As you can see, SAP BODS readily adapts to your existing infrastructure while keeping future scale, resilience and cloud migration needs in mind.
Okay enough theory – let‘s get our hands dirty with some real examples!
Simplified Core Concepts
I know jumping into a new complex tool can be intimidating with all the unfamiliar terminology thrown around! Let‘s demystify some key building blocks:
Repository
This is the metadata database holding all your data connections, credentials, mappings, model flows and dependencies in a centralized fashion. Think of it like a catalog or inventory system enabling collaboration, impact analysis and reuse across teams. I‘ll show an example schema later.
Datastore
Datastores abstract away the connection details and specifics of all your underlying sources and destinations like files, databases, apps. So if say the location or access credentials change for an enterprise database, you only need to update the datastore definition instead of modifying all dependent integration jobs!
Data Flow vs ETL Job
This tripped me up initially too! Data flow refers to the logical model mapping data across different datastores via transformations, lookups etc. while ETL job represents actual execution runtime artifacts that process the data by reading and writing to endpoints. Hopefully the examples will clarify this relationship.
Services
Now things get spicy! By services, SAP BODS refers to specialized processing that you can invoke within data flows without having to write custom code. For instance, address standardization, matching Potential duplicates, encrypting columns and transcoding data formats on the fly to name a few. This plug and play functionality saves tons of grunt work.
Okay, lets take a breath. With the basics squared away, we have just enough context to start our first hands-on walkthrough.
Step-by-Step Data Integration Tutorial
The best way to cement concepts is by getting our hands dirty with a realistic demonstration. We will build an end-to-end pipeline that:
- Fetches raw customer demographic data from a database
- Enriches by finding potential duplicate records
- Filters only US subscribers
- Loads final dataset into CSV formatted file
As we build this out, you will gain exposure across critical areas like datastore setup, leveraging services, mappings and executing job runs.
Let‘s do this pal!
Step 0: Install and Launch SAP BODS
I won‘t bore you with the OS-level installation details, but within minutes you can setup an Eclipse based dev environment with sample repository on your local machine.
The bundled mock warehouse comes preloaded with Sybase, SQL Server, mySQL and file-based data structures covering typical use cases. Very handy for dummy test runs even without access to actual corporate data assets when starting out.
Once launched, the BODS homepage contains handy samples and templates to accelerate learning:
The toolbox on left provides commonly used transformations, lookups, scripting components and other building blocks to drag-drop onto the designer workspace.
Step 1: Define Source and Target DataStores
Recap that datastores provide abstraction and insulation from actual database instances and file storage details. This becomes useful as infrastructure evolves.
Let‘s create two datastores:
Source – ExistingSybaseDB pointing to our prepopulated demo warehouse data. Connect over standard ODBC.
Target – EnrichedCustomers mapped to local directory location where we will write output CSV file.
If working with actual corporate systems, corresponding production credentials and real-time connections need configured here.
Step 2: Construct Data Flow
With endpoints defined, now we can visually build out the logical ETL sequenced using the pictorial editor:
Let‘s interpret this:
a) Extract raw customer demographic records from Sybase DB
b) Standardize addresses for consistent parsing using in-built service
c) Identify potential dupes using fuzzy matching algorithm to cleanse data
d) Filter only US subscribers for our scenario
e) Redistribute flow across 4 parallel threads based on hash code for performance gain
As you drag and drop elements like filters, routers, lookups and external service nodes – the flow composer validates for errors on the flyaccelerating debug. Very handy during initial prototyping iterations!
Step 3: Execute and Monitor ETL Job
Alright time for the moment of truth! We kick off the job run which spins up a controller process:
- Orchestrates splitting data flow model into execution runtime artifacts
- Provisions infrastructure resources like servers, memory to create scale out parallel runtime containers
- Monitors and tracks runtime metrics for each microbatch streaming through the system
The management console provides a centralized dashboard allowing drill down into current and historical job executions:
Beyond basic metrics like data volume processed, duration and memory consumption – we get granular visibility into the parallel operators. Very useful for tuning bottlenecks!
Step 4: Verify Output File Contents
Once the batch completes successfully, we can inspect resulting csv file with US customer subset containing deduped list based on our orchestrated data flow logic!
Our small sample pipeline touched on key aspects like datastore configuration, service integration and job creation. But in complex enterprise data hubs with 1000s of pipelines, additional best practices around organization, reuse and troubleshooting apply.
Handy Tips for Enterprise Data Platform Management
Through the tutorial, you saw first-hand how SAP BODS accelerates developing data integration use cases. But what separated guidelines ensure smooth operations as complexity increases in large teams?
Here are 5 key takeaways based on experience:
Reuse Algorithms and Modules
STL helps software engineers avoid duplicate logic and bugs by publishing common libraries. Similarly create custom reusable utilities in BODS handling mundane stuff like NULL checks, data type handling. Promotes consistency.
Abstract Parameterized Config
Dynamic, context-aware configurations avoid hard coding values like business logic thresholds all over jobs. Maintain as external parameters exposed through job properties. Ties code to business rules.
Standard Naming Conventions
Use consistent prefixes, suffixes as cues across projects. For instance Customer_LoyaltyIndicator, OrderHeaderTransform. Improves understandability over time as team grows.
Modular Pipeline Components
Avoid mammoth end-to-end flows impossible to debug or modify. Break into smaller building blocks executing specific stages focused on filtering, massage, shuffle etc.
Implement Mock Test Bench
Setup canned configurations simulating various loads like peak seasonal scale. Run suites for every build to catch downstream breaks.Shifts left error detection.
These coding and design guidelines help keep complexity in check. Peer reviews before check-in further improve quality!
Now that you have familiarity with the functionality and administration – where do bottlenecks typically arise during large volume production runs?
Mapping Optimal Architecture to Performance Needs
Beyond great code, the deployment architecture itself is vital for peak data pipeline throughput and resilience in 24/7 environments.
Let‘s examine three critical scaling dimensions – data volume, concurrency and throughput:
Horizontally scale out independent flows across more processing nodes. This ensures linear speedup by leveraging parallelism during high data loads like seasonal peaks or black friday sales events.
Remove concurrency bottlenecks with non blocking asynchronous flows using Kafka queues. Achieve over 5000 TPS throughput.
Enable caching and temporary storage mechanisms like Redis for commonly needed static reference data to avoid redundant RDBMS fetches.
Based on your unique workload patterns, the ML-based Workload Optimization Assistant profiles usage over 2 weeks before providing a dramatically simplified blueprint highlighting optimal deployment architecture. This reduces guesswork!
For example, a 25% QoQ data growth for manufacturing industry with compliance needs translates to:
Environment: On-premise and Cloud Hybrid
Performance: Linear scalability to 8+ nodes
Cost savings: 45% by enabling cloud burst buffer The assistant keeps your architecture aligned to business priorities automatically even as needs evolve!
Expanding the Capabilities using AI
Now that you understand the extensive capabilities…did you know AI recommendations help squeeze maximum productivity when building flows across projects?
Let me walk you through a smart example:
1. Start creating new flow for inventory fact table
2. Design assistant identifies semantic similarity to prior vendor dimension ETL logic
3. Recommends reuse of 60% existing components from old flow
4. Adapts remaining modules to new incremental load needs
5. Accelerates development effort by 5 days!As you design pipelines, the assistant continuously looks for reuse while assessing new functionality needed – across 1000s of historical data flows!
By leveraging institutional knowledge, it allows you to focus on value-add differentiators for your business vs. reinventing routinized plumbing. Pretty rad eh?
