kdb+ vs. MonetDB

kdb is well suited for real time tick data and time series analytics.

MonetDB is great when you are performing adhoc queries on a large set of data. For example, if you store data in a typical RDBMS such as MySQL or Postgres and want to join large tables for analytics but the query runs unacceptably slow then MonetDB can act as a second database to offload complex queries. Based on my experience, it may not be a production-ready database since there aren't many DBAs familiar with it and due to lack of documentation, maintenance can become a little tricky.

• Time series analysis. The built-in vector operations are extremely fast. Also with the q language you can code up any customized analytical ideas quickly.
• The database are all file based, very easy to maintain.
• Very solid and fast interface to websocket, so you can interface with javascript easily.

Incentivized

• It is easy to use.
• You are able to input lots of data and it understands and populates information.
• Able to change settings on the fly to use with your needs.

Incentivized

• Run time error message readability, particularly for new users.
• Backwards compatibility between versions.

Incentivized

• This is an open source software so there are obvious drawbacks, the biggest of which is a lack of documentation.
• MonetDB does not seem to be well known outside of the academic environment so there is less information when you are searching for answers of any type.
• I'd like to see more use cases and/or best practices so that commercial companies like ours can optimally use all of its highly performant features.
• The code is written in C/C++ and this can be negative if you are a mainly java-shop and need UDF - User Defined Function.

Python is very commonly used for large data analysis and in general is much easier to pickup than kdb+. The biggest drawback of kdb+ is the learning curve.

We have used Five9 in my previous company but on a much smaller scale. It was more expensive, however we were using it for a max of 50 employees, now we need a much bigger platform. We also used Five9 for other things, like phone dialers etc. so it was a little different.

• It perfectly solves most of our real time tick data needs.
• Finding good kdb resources is slightly difficult. Also new people trying to learn kdb experience a relatively longer learning curve.

Incentivized

• If you are familiar with a general database concept and played with open source products before then MonetDB will give you immediate return in terms of productivity since developers can quickly develop and verify their test cases involving back-end database with a large sample data set.
• There is a stiff learning curve due to lack of documentation and sparse information available on the internet.
• Overall experience has been positive since MonetDB gives you another option when it comes to building out a data warehouse.
