lookupCache.maxElementsInMemory parameter

The lookupCache.maxElementsInMemory parameter defines the maximum number of Lookup Tables that can be cached in memory per JVM instance.

Parameter values

Value: Integer
Default value: 100
Recommended value: 100

During startup, if your system finds that the parameter value is missing or invalid, the parameter value will automatically revert to the system default value of 100.

Set the cache size according to your system requirements, by viewing the cache hit ratio for Lookup Tables in the user interface. Make adjustments to your setting until the hit percentage is over 95%.

Recommendation: To avoid running out of memory, if a solution has large Lookup Tables with entries greater than 1000, then the cache size must be kept small regardless of your hit percentage.

Example

In this example, the maximum number of Lookup Tables is 100.

lookupCache.maxElementsInMemory=100
