// 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.
