I’ve recently started my journey with Apache Flink. As I learn certain concepts, I’d like to share them. One such "learning" is the expansion of array type columns in Flink SQL. Having used ksqlDB in a previous life, I was looking for functionality similar to the EXPLODE function to "flatten" a collection type column into a row per element of the collection. Because Flink SQL is ANSI compliant, it’s no surprise... - Source: dev.to / about 9 hours ago

You should let the Apache Flink team know, they mention exactly-once processing on their home page (under "correctness guarantees") and in their list of features.

Data scientists often prefer Python for its simplicity and powerful libraries like Pandas or SciPy. However, many real-time data processing tools are Java-based. Take the example of Kafka, Flink, or Spark streaming. While these tools have their Python API/wrapper libraries, they introduce increased latency, and data scientists need to manage dependencies for both Python and JVM environments. For example,... - Source: dev.to / about 1 month ago

Other stream processing engines (such as Flink and Spark Streaming) provide SQL interfaces too, but the key difference is a streaming database has its storage. Stream processing engines require a dedicated database to store input and output data. On the other hand, streaming databases utilize cloud-native storage to maintain materialized views and states, allowing data replication and independent storage scaling. - Source: dev.to / 3 months ago

Also, this knowledge applies to learning more about data engineering, as this field of software engineering relies heavily on the event-driven approach via tools like Spark, Flink, Kafka, etc. - Source: dev.to / 5 months ago

The proof that the data doesn't exist? Go to statista.com and look for "bumble height" or any other search term you think is needed to find that chart. Then reflect on how nothing on the chart is how a scientific outlet would do a chart, and especially not Statista. This is done by an amateur who has no idea about designing charts that meet any scientific standard. Source: 11 months ago

For those who aren't aware, FedEx Ground is made up of independent contractors. FedEx Express is the original FedEx. Yes, by nature of the business, if you ship something FedEx ground it takes longer, and the longer it takes and the more hands that handle a package the more chance there is for loss, damage, or delay. If you ship something through FedEx Express you generally get things much faster and have a better... Source: about 1 year ago
