Overview ¶
Package symbolizer provides a string interning mechanism to reduce memory usage by reusing identical strings.
The Symbolizer maintains a cache of strings and returns the same instance when the same string is requested multiple times. This reduces memory usage when dealing with repeated strings, such as label names or values. It is not thread safe.
When the cache exceeds the maximum size, a small percentage of entries are randomly discarded to keep memory usage under control.
