Question

>there are many real examples that the size of string dictionaries becomes critical problems for very large datasets

This seems very intriguing, but would it also be helpful for small[er] string dictionaries (e.g. for Julia Base and the Julia compiler)?

Start by reviewing the issue text and the existing DoubleArrayTries.jl implementation; no files, tests, or entry points are identified in the report. The issue provides no concrete change or completion criterion, so clarification of the intended improvement would be needed before implementation.
