|This option affects the [[Indexes#Performance|construction]] of new value indexes. It controls the number of index build operations that are performed before writing partial index data to disk:
* The larger the assigned value is, the less splits will take place, and the more main memory will be required.
* By default, if the value is set to {{Code|0}}, some heuristics are applied, based on the current memory consumption. Usually, this works fine. If explicit garbage collection is disabled when running Java (e.g. via the JVM option `XX:+DisableExplicitGC`), you may need to choose a custom split size.
