If you just want to prevent other users from snooping you, use VLAN. There's no protection against the network administrators though.

The problem with most metadata catalog is not technical, but the human: Catalog are documents for data, and developers hate writing documents.

I really like the architecture of Pulsar, it is very elegant with clear separation of duties between components. That said, we have used Kafka for so long, and it works well enough at our scale that we have no reason to even test Pulsar. Ka

We have never been able to make Hive LLAP run reliably on our HDP cluster, queries sometimes just hang for no apparent reason. On the other hand, our Presto cluster runs pretty much anything we throw at it, and when it fails, the failures a

We only use NiFi on the edge of our data lake. It's very good at bulk loading, pulling log files/sensor data from hundreds of systems into our systems. However, it does not handle small records well, and deploying custom processor

Ehh, what you just described is often how service versioning works: launch a v2 service with the v1 still active, keep them running concurrently for a while, then turn off the v1 when it's no longer used. You can distinguish the versio

Prometheus is not really a database, because the only operation allowed is query, you can't insert/delete data manually. For many use cases, that's not acceptable.

No, he made a good point. It's a matter of perspective, what is considered data in one situation, can be consider code in other situations. Hell, they even created the NX-bit to prevent malicious memory space becoming executable.

For this amount of data, I would use good old Postgres, partition the data by ingestion time, then just detach the old partitions when you need to archive it. For joining data from multiple database, if the data is large, I would use someth

I hate it too, but I can't completely fault them. Companies need to be profitable, and the pricing race to the bottom means they can hardly increase individual pricing, which in turn force them to exploit other directions.

To be fair, Window XP's firewall cannot block Outgoing connection, only Incoming. Vista SP1 and later versions of Windows include a firewall with Outbound blocking.

From reading their documents, I really like the design of Pulsar. However, Kafka has been working so well for us and has much better integration with other components of our stack (Flink, Spark, NiFi, etc) that there's no compelling re
