kop VS doris

I process hospitality data somewhat similarly, but use Pulsar and can individually acknowledge messages, have DLQs built in, and if needed can stream just like Kafka. And if I need Kafka compatibility, I can use something like StreamNative's KOP and get Kafka compatibility over my existing Pulsar queues.

While Pulsar has its own protocol that handles streaming, queues, and a lot of the other features (distributed transactions, functions, etc.), it can also speak other messaging protocols via plug-ins. Looking around, the ones that appear to be actively developed are MQTT, Kafka (so your existing applications that use Kafka can also use Pulsar), AMQP, and JMS.

Like in many databases, Apache Doris shards data into partitions, and then a partition is further divided into buckets. Partitions are typically defined by time or other continuous values. This allows query engines to quickly locate the target data during queries by pruning irrelevant data ranges.

What makes a modern database system? The three key modules are query optimizer, execution engine, and storage engine. Among them, the role of execution engine to the DBMS is like the chef to a restaurant. This article focuses on the execution engine of the Apache Doris data warehouse, explaining the secret to its high performance.

For most people looking for a log management and analytics solution, Elasticsearch is the go-to choice. The same applies to InfluxDB for time series data analysis. These were exactly the choices of NetEase, one of the world's highest-yielding game companies but more than that. As NetEase expands its business horizons, the logs and time series data it receives explode, and problems like surging storage costs and declining stability come. As NetEase's pick among all big data components for platform upgrades, Apache Doris fits into both scenarios and brings much faster query performance.

This is an in-depth introduction to the workload isolation capabilities of Apache Doris. But first of all, why and when do you need workload isolation? If you relate to any of the following situations, read on and you will end up with a solution:

Apache Doris is an all-in-one data platform that is capable of real-time reporting, ad-hoc queries, data lakehousing, log management and analysis, and batch data processing. As more and more companies have been replacing their component-heavy data architecture with Apache Doris, there is an increasing need for a more convenient data migration solution. That's why the Doris SQL Convertor is made.

As an open-source real-time data warehouse, Apache Doris provides semi-structured data processing capabilities, and the newly-released version 2.1.0 makes a stride in this direction. Before V2.1, Apache Doris stores semi-structured data as JSON files. However, during query execution, the real-time parsing of JSON data leads to high CPU and I/O consumption in addition to high query latency, especially when the dataset is huge and complicated. Moreover, the lack of a pre-defined schema means there is no handle for query optimization.

Apache Doris is a real-time data warehouse.

As you can imagine, a long and complicated data pipeline is high-maintenance and detrimental to development efficiency. Moreover, they are not capable of ad-hoc queries. So as an upgrade to our data warehouse, we replaced most of these components with Apache Doris, a unified analytic database.
