describeDatabase

public final void describeDatabase(Void ctx,
 DescribeDatabaseRequest request,
 Observer<HttpBody> observer)

  Get a text-dump describing a database
 
  This operation can be used to debug the inner workings of RocksDB database.
  For example the property rocksdb.estimate-table-readers-mem will provide an
  estimation of how much memory is used by the index and filter cache of
  RocksDB (note that the memory used by RocksDB is outside the java heap space).
 
  See also: https://github.com/facebook/rocksdb/blob/master/include/rocksdb/db.h
 
  The response contains a dump of various rocksdb properties for each column
  family. The single value properties are presented in a "name: value" list.
  The multiline properties are preceded by a line including the property name
  between dashes.
