A string interning library for Go
intern has a number of benefits
- It deduplicates strings. if you have data that references identical text in very many different places if may significantly reduce the amount of memory used for the strings.
- It stores the strings in a way that reduces the load on the garbage collector.
- It allows you to store an int ID for the string instead of the string itself. This is considerably smaller, and again is GC friendly.
i := intern.New()
hat := i.Save("hat")
fmt.Printf(i.Get(hat))

Overview ¶
Package intern is a string interning library. Pass it a string, and it will store it and return it, removing duplicates. That is, however many times you show it a string, it will only store that string once, and will always return a version of it backed by the same memory.
Storage is kind to GC. It is optimised for storing a very large number of strings.
