ClickHouse vs. SAP Adaptive Server Enterprise (ASE)

The most important thing when using ClickHouse is to be clear that the scenarios in which you want to use it really are the right ones. Many users think that when a database is very fast for a specific use case, it can be extrapolated to other contexts (most of the time different) in which a previous analysis has not been carried out.

ClickHouse is an analytical database, as such, it should be used for such purposes, where the information is stored correctly, the data volumes are really large and the queries to be performed are not the typical traditional queries on several columns with multiple aggregations. ClickHouse is not the solution for this.

On the other hand, if your case is not one of the above, it is quite possible that ClickHouse can help you. Where ClickHouse shines is when you are looking for aggregation over a particular column in large volumes of data.

We use this for an inbuilt security management system, where it performs well in a scaled setup with a large volume of live data with high availability. Also, the performance is up to the mark for the large statement flow. From a DBA perspective, a lot of parameters need to be fine-tuned for the specific environment needs, which can cause overhead. Expertise is limited, and the learning curve is steep for the SAP ASE.

• Their MergeTree table engine provide impressive performance for data insert in bulk
• Not only data insert but also the way MergeTree engine uses Primary Keys to sort the data and perform data skipping based on the granules its also their secret for ridiculous fast queries
• Data compression its also great
• They provide especial table engines that allow you to read data directly from other sources like S3
• Since its written with C++ you have very granular data types and especial ones like enum, LowCardinality and etc, they save you a lot of storage since are stored as integer values
• ClickHouse functions besides the ones that respect ANSI Standards are also awesome and useful

• High availability and reliability.
• High performance.
• Monitoring of threshold based events.
• Security at multiple levels.
• Query plan optimization.
• Lock management.
• Access to HANA.

• Avro data manipulation
• Kafka consistency
• DDL operations errors (by replica configuration)

• A quick button for devs to switch instances into a dev mode (eliminating logs, and such).
• Licensing is far too complicated. Simplify pricing.

Our licenses are perpetual. It is the support that we will be renewing. We will renew because we continue to use and receive value from the product.

Well-suited in the security domain, high performance, and low latency of the DBMS. In terms of the DBA perspective, a dedicated monitoring tool (Cockpit) helps a lot in terms of managing the database, which helps in identifying bottlenecks during performance issues. Also, it helps us to send custom alerts related to Database activities.

Incredibly responsive, saving us countless hours in troubleshooting.

ClickHouse outperforms, especially in costs, since its compression/indexing engines are so smart, and even with very low computing power, you can already perform huge analyses of the data.

• Queries that used to take more than 2 minutes now take less than 1 second
• Possibility to analyze use cases in real time (before was impossible)
• The applications are more complete and the users decisions are better

Incentivized

• Positive ROI.
• Ease of use with minimal training required to write high performance SQL (assumes a knowledge of SQL already).
• Ease of database administration.
• Sometimes upgrades can be difficult.
• Changing platforms can be difficult (changing say from SPARC to Intel).
• Changing operating systems can be difficult (changing from Solaris to linux).
