Column type must be of one of a predefined set of available 'primitives' (including Strings, UUIDs, date & time values)
Arbitrary nested objects and collections are not allowed as column values. Nested POJOs should either be inlined into schema, or stored as BLOBs
Date & time values should be compressed with preserving natural order and decompression should be trivial operation (like applying bitmask).

The suggested list of supported built-in data types is listed in the table below:

Type	Size	Description
Bitmask(n)	⌈n/8⌉ bytes	A fixed-length bitmask of n bits
Byte	1 byte	1-byte signed integer
Short	2 bytes	2-byte signed integer
Integer	4 bytes	4-byte signed integer
Long	8 bytes	8-byte signed integer
Float	4 bytes	4-byte floating-point number
Double	8 bytes	8-byte floating-point number
Number([n])	Variable	Variable-length number (optionally bound by n bytes in size)
Decimal	Variable	Variable-length floating point number
UUID	16 bytes	UUID
String	Variable	String encoded with a given Charset
Date	3 bytes	A timezone-free date encoded as day/year (15 bits), month (1 byte4 bits), year day (2 bytes5 bits)
Time	5 4 bytes	A timezone-free time encoded as padding (5 bits), hour (1 byte5 bits), minute (1 byte6 bits), second (1 byte6 bits), millisecond (2 bytes10 bits)
Datetime	8 7 bytes	A timezone-free datetime encoded as (date, time)
Instant	8 bytes	Number of milliseconds since Jan 1, 1970 00:00:00.000 (with no timezone)
BLOB	Variable	Variable-size byte array
