This post is a high level overview of the design and architecture of Gutenberg. Often the data is held in memory by consumers and used as a “total cache”, where it is accessed at runtime by client code and atomically swapped out under the hood. An important point to note is that Gutenberg is not designed as an eventing system?—?it

These issues often arise from suboptimal query design, missing or ineffective indexes, or dealing with large datasets. Inefficient query design, such as utilizing SELECT * instead of specifying necessary columns, can escalate data transfer and processing overhead. Another highly beneficial caching method is key-value caching.
