ets_manager

Separate management of ets tables to prevent lost data.

Description

This library will allow tables to be created that will have it's 'heir' as the manger process. It will then assign the table to the calling process. If the process dies unexpectedly the table returns to the manager process.

Add the library to your rebar config

{
  deps,
  [
   {ets_manager, {git, "https://github.com/erlsci/ets_manager.git",
     {tag, "v0.4.0"}}},
   ....
  ]
}.

Then just use rebar3 to automatically download and compile as part or your project

$ rebar3 compile

Breaking Changes

Note that in v0.4.0, the function give_me was renamed to create_or_return. If you need the old name, be sure to use the v0.3.0 release.
