Understanding high memory usage for fielddata cache

(Morgan Hamill) #1


I am looking for help with understanding why the fielddata cache for a certain field is so large.

Towards that end, I was wondering if anyone could describe to one or both of:

  • A formula for estimating the usage of the fielddata cache.

  • A description of the default, in-memory data structure used to store the cache.

I'm looking to properly grok this, so please feel free to use whatever level of techical detail you think is needed.
