To read about the technical failures, which lasted for many years, increases my respect for MongoDB, which was a bit more aggressive tackling the technical problems that haunted its early years. MongoDB had a partially deserved bad reputation for thinks like locks, but they worked hard to improve that. It had a bad reputation for consistency errors but they worked with Kyle Kingsbury to find the flaws and eventually overcome them. In contrast, it sounds like Ingres was not able to create row level locking, even after many years of it being a crucial factor that was allowing Oracle to win. I wonder if Ingres was too careful with investment? Sounds like Oracle nearly destroyed itself during the hypergrowth phase. This phase of growth seems to be something investors now understand better. Indeed, rather than considering it a weakness, hockey stick growth curves have become a requirement.
