Class DefaultColumnFamilyNameConverter

java.lang.Object
org.openspaces.persistency.cassandra.meta.conversion.DefaultColumnFamilyNameConverter
All Implemented Interfaces:
ColumnFamilyNameConverter
public class DefaultColumnFamilyNameConverter extends Object implements ColumnFamilyNameConverter
A ColumnFamilyNameConverter implementation that works as follows: If the type names length does not exceed a 48 characters length, the dots in the type name will be replaced by underscores. Otherwise, the type simple name (without the packages prefix) will be used with the first 6 chars of the string representation of the given type name MD5 hash to avoid name collisions. If the above also exceeds a 48 characters length, the simple name will be truncated to its first 42 characters and concatenated with the MD5 suffix mentioned above.
