FastGlobal is an Elixir/Erlang library that provides fast, copy-free access to large shared global data by leveraging the Erlang VM's constant pools via runtime module compilation. It is a modernized Elixir take on mochiglobal, optimized for large, infrequently changing data read by many processes.

Use cases

• store large lookup tables accessible by thousands of BEAM processes without copying
• replace ETS reads that get slower as data grows
• share infrequently changing configuration across an Erlang cluster of processes
• avoid overloading a single process holding shared state
• get near-constant-time global reads in Elixir applications

When to choose

• you have large, rarely changing data read frequently by many processes on the BEAM
• ETS read costs or process-based state are bottlenecks
• you want a drop-in global map API in Elixir

When to avoid

• your data changes frequently, since puts and module purges are expensive
• your dataset is small enough that ETS is fast enough
• your system has many processes, making module purge compile times slow
• you frequently look up missing keys, which triggers costly try/catch
