# NodeTableCacheFields

Set `NodeTableCacheFields` to `True` to store specified fields in a cache. To specify the fields to cache, configure the fields with the MemCachedType property.

NOTE: You cannot use this option for fields that occur multiple times in a document.

For example:

    [FieldProcessing]
    .....
    15=CachedFields
    .....

    [CachedFields]
    Property=SetPrintFields
    PropertyFieldCSVs=*/DREREFERENCE,*/DRETITLE,*/IMAGE,*/PAPER,*/SUMMARY,*/DOCTYPE
    .......

    //---------------------------Properties------------------------//

    [Properties]
    ......

    [SetCachedFields]
    MemCachedType=True

Use the MaxSize configuration parameter to specify the maximum size of the cache. Use the EvictWhenFull configuration parameter to specify whether to delete old entries from the cache when new entries are added after it is full. Use the NodeTablePrepopulateCache parameter to load the field cache when IDOL Server starts.

If the MaxSize is reached, old items are deleted. Therefore, enable field caching to store only fields that are regularly accessed in your queries.
