How updating the keys works?
When you update the key does it occupy the extra space in memory or use the existing space? i mean we are planning to update the 10 million records every 5 minutes, trying to estimate the size of memory keys are going to use, does the total used memory would be 1.19GB?
And what kind of issues we would face while updating 10 million keys every 5 minutes? since we are updating a key every 5 minutes would we face the hot key problem?
