| // CollationCache implements a persistent in-memory cache for |
| // TableCollationData objects. The goal of CollationCache is to improve |
| // the memory footprint of a process which may have multiple threads |
| // loading up the same TableCollation object. Performance improvement is |
| // strictly a secondary goal. |
