Hi,<br><br>In my application, I have to store a huge (but sparse) 2D matrix. I implemented that successfully using dict-of-dict kind of structure.<br><br>I was then thinking to use a ets-of-dict structure: each line is a dict (containing all colum values) and I store each line (a dict) as an entry of a ets structure.
<br>But I read in the doc introduction of ets that "In the current implementation, every object insert and
look-up operation results in one copy of the object.". Does this means that each access (even read) to an element of my matrix would imply a new dict copy?<br>
