Some time ago, I wrote 《Ripple: When the generic method meets the abstract class-my "Memory Database" birthnotes", Recorded the design process of the PDF. Net memory database, and made some minor changes recently. It has been put into production and is currently running well. I looked at the source code again today and thought it was necessary to draw a structura

For a system with massive data volumes, the performance bottleneck will eventually fall on the database. At this time, hardware upgrades and program optimization are powerless, A simple query may also impose a heavy burden on the database. Grid computing divides a problem that requires a huge amount of computing power into many small parts, and then assigns these small parts to many computers for processing
