Understand the text data types available in Cassandra.
- [Instructor] There are three kinds…of string data types in Cassandra,…ASCII, VARCHAR, and Text.…ASCII is used to represent US-ASCII character strings.…There are 127 such characters.…VARCHAR is used to store UTF-8 encoded strings.…ASCII characters are a subset of the UTF-8 encoded strings.…UTF-8 encoded strings are backward compatible with ASCII…and UTF-8 is used to encode Unicode characters.…
There are over 128,000 characters defined in Unicode.…Text is also used to store UTF-8 encoded strings.…Text is an alias for VARCHAR…and the two can be used interchangeably.…Examples of ASCII characters includes letters and keyboard…characters commonly used by U.S. English speakers.…The UTF-8 character sets include…specialized currency symbols,…as well as characters in non-Latin alphabets.…
There are two time data types, Timestamp and TimeUUID.…The Timestamp data type is the date plus the time…encoded as eight bytes since the Unix epoch,…which is defined as starting at midnight January 1, 1970.…Timestamps are the number of milliseconds since the epoch.…
