# Information Schema Reference

Views in the information schema (Holds the information or metadata for all the databases in a cluster.) surface metadata about clusters and all the components within them. SingleStore supports the same `information_schema` views as MySQL, as well as a variety of additional views that are specific to SingleStore. The MySQL views are often useful, but it is important to note that some are included mostly for compatibility purposes, meaning that values for some columns may always be `NULL`.

Many of the information schema views have an `mv_` version, which is a view that aggregates over `lmv_` views that are generated independently on each leaf.
