Performance when going from on-premises to the cloud Moving data from on-premises to the cloud is challenging with enough data in the play. Cloud vendors even allow you to ship hard disks over (Azure Import/Export service, AWS Import/Export, AWS Snowball…) because the network is ultimately always limited. Besides network bandwidth, ping is another enemy. When you send a packet over a TCP/IP network connection, you wait for delivery confirmation before another packet is sent. That, of course, means delays. The way to combat network bandwidth limitation is through strong compression on-premises and moving only the compressed data over the wire. We use Parquet to load data into data warehouses with typically 80% data reduction. The way to combat ping is parallelism. Omni Loader does all its job items in parallel. Not only will it copy multiple tables (via Parquet) in parallel, it will automatically slice the data of a single table to enable many table parts to be processed and uploaded in parallel. Of course, this is all fully automatic and optimal out of the box.

Extracting data out of Synapse When moving data from Synapse Dedicated Pool to Fabric, there are several ways to read and write the data. On the Synapse side, you can read data using SQL. Even with large clusters, this means that a single node will collect all the data and serve it to your application through the connection. Good thing here is that you have a full T-SQL expression power to fetch your data. You can then export that data yourself in any form you need. You can choose to export data using Polybase, in which each Synapse node will export its chunk of data independently, for example into ADLS Gen 2 Parquet. You lose the ability to use SQL transformations, as well as the ability to know how much data is being processed. You basically fire the job up and wait. Omni Loader can use both approaches, and load that efficiently into both Fabric Lakehouse and Warehouse. https://lnkd.in/ezvB-72N #DataMigration #Synapse #Fabric #SQL #Polybase #Fabric #AzureSynapse #ADLSGen2 #TSQL #FabricLakehouse #OmniLoader

Is JSON a good intermediary file format? JSON is a textual hierarchical data format designed to be human-readable. It is fairly verbose, but it is also fairly readable and easy to use. JSON is JavaScript's native data format. Before JSON we had XML, but the problem with XML is it's extremely verbose and over-engineered. XML has schemas and attributes, and that makes it simply harder to use compared to the very simple JSON format. The question is, for what is JSON a good format and when should you use something else? For moving data over the wire, JSON is a sensible default. JSON data serialization won't end up with a small data size as keys are repeated for each value unless arrays are used. However, until that's a problem, JSON is just fine. One can optimize serialization by using more efficient binary serialization such as protobuf, but then convenience is greatly reduced and one loses the ability to visually inspect the data. #JSON #JSONFormat #DataFormat #EfficientDataTransfer #DataInterchange #JSONBenefits #DataSerialization #DataParsing #DataRepresentation #OmniLoader https://lnkd.in/erJUgrnq

📈 Omni Loader Console Mode: Script and Automate Your Migrations Without Using Web-Based UI 📈 🔍 How is Console Mode useful for you? Omni Loader Console Mode brings a new level of efficiency and automation to your data migration projects, eliminating the need for a web-based UI. Here's how Console Mode stands out: Console Mode JSON files are easy to understand – and declarative. You can see all the customizations right away, as there is no need to flick through different screens to examine what has been applied. This feature is especially valuable in a multi-user environment, where a colleague coming to the project can immediately grasp the requirements. An additional benefit is that JSON project files can be put into the source control, for security and audit purposes. #datamigration #databasemigration #OmniLoader #sqlserver #postgresql #consolemode https://lnkd.in/ezshvxTA

🚀 Data Migration Redefined with Omni Loader 🚀 Data migration isn't just a one-time, one-off task—it's a complex, ongoing project that requires moving large quantities of data efficiently. This process often requires continuous streaming of data from the source to the target for the entire duration of the project. For such critical tasks, CDC (Change Data Capture) is crucial. It captures transactions on the source and replays them on the target, ensuring data is current and synchronized. Enter Omni Loader, crafted to streamline this process through several key stages: 1️⃣ Starting transaction capture on the source. 2️⃣ Initial load, which involves copying the entire database. 3️⃣ Replaying the captured transactions on the target, accommodating any necessary data transformation, especially in heterogeneous database situations. Omni Loader's design is focused on ease of use: enabling CDC happens automatically, the initial load operates on a massively parallel high-performance migration engine capable of handling millions of records per second, and the transaction replay is not only efficient but also robust against common issues like unstable networks. https://lnkd.in/edk2Ti6t #DataMigration #ChangeDataCapture #OmniLoader
