This article provides the technical limitations of Jedox In-Memory DB, Jedox Web, and Jedox Integrator.
Limits of Jedox In-Memory DB
The Jedox In-Memory DB has technical limitations for the size of objects, such as the number of elements in a dimension, or the number of dimensions in a cube. These limits are listed below. Please note that these are technical limitations, not recommended values.
- The number of objects with ID is limited by a 4-byte-long unsigned integer. This corresponds to 2^32 = 4,294,967,296 objects.
- The number of numeric values in a cube is limited to 60 billion (guaranteed - can be expected to be 400 billion due to data compression).
- The length of all string values together in a cube is limited to 4,294,967,296 characters (including terminating zeros).
- The length of all element names together in a dimension is limited to 4,294,967,296 characters (including terminating zeros).

1) The maximum level applies to the sum of individual values as specified at the beginning.
2) The data storage needs approximately 10-15 bytes for a numeric value. A sample database with a realistic dimension with 1.3 million elements needs about 305 MB.
3) The practical limit for databases is constrained by the available RAM, disk space, and the Operating System. A high amount of databases can impact the performance of individual requests. It is recommended to keep the number of databases below 100 as maximum.
4) The number is technically limited by the processing limitations of the PALO.DATA functions to 250 dimensions, but it is strongly recommended not to use more than 30 dimensions in a cube.
5) Tested with 13 million elements.
6) In Jedox Web, the maximum result size of subsets, such as in comboboxes, is limited to 65,336 elements by default. Cloud customers can request specific configurations by contacting Jedox Support. See also Custom Configurations for the In-Memory DB (OLAP).
