Shard Naming Shard names have the following characteristics: • They represent a range in unsigned integer space, where the left number is included, but the right is not. • Their notation is hexadecimal. 80- means: ‘anything greater than or equal to 0x80 A hash type vindex produces an unsigned 64 bit integer as output. This means that all integers less than 0x8000000000000000 will fall in shard -80. Any VReplication supports copying & streaming across multiple character sets. Moreover, it supports conversion from one character set to another. An important use case is importing from an external data source
