 ## In a nutshell
 
-`Heap` memory offers the best performance for accessing data, both for reading and writing. However, it has a limited capacity in terms of the space it can occupy, with a max of 2 GB.
+`Heap` memory offers the best performance for accessing data, both for reading and writing. However, it has a limited capacity in terms of the space it can occupy, with a max of 1 GB.
 
 On the other hand, `stable` memory has a higher memory threshold with a maximum limit of 96 GB minus the heap size, allowing it to store more data in terms of size. However, it is slightly slower.
