INTEGER Type
INTEGER
Possible values: -2147483648 to 2147483647.
Mapped to java.lang.Integer. The binary representation is a 4 byte integer with the sign bit flipped (so that negative values sorts before positive values).
Example:
INTEGER
UNSIGNED_INT Type
UNSIGNED_INT
Possible values: 0 to 2147483647. Mapped to java.lang.Integer. The binary representation is a 4 byte integer, matching the HBase Bytes.toBytes(int) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_INT
BIGINT Type
BIGINT
Possible values: -9223372036854775807 to 9223372036854775807. Mapped to java.lang.Long. The binary representation is an 8 byte long with the sign bit flipped (so that negative values sorts before positive values).
Example:
BIGINT
UNSIGNED_LONG Type
UNSIGNED_LONG
Possible values: 0 to 9223372036854775807. Mapped to java.lang.Long. The binary representation is an 8 byte integer, matching the HBase Bytes.toBytes(long) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_LONG
TINYINT Type
TINYINT
Possible values: -128 to 127. Mapped to java.lang.Byte. The binary representation is a single byte, with the sign bit flipped (so that negative values sorts before positive values).
Example:
TINYINT
UNSIGNED_TINYINT Type
UNSIGNED_TINYINT
Possible values: 0 to 127. Mapped to java.lang.Byte. The binary representation is a single byte, matching the HBase Bytes.toBytes(byte) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_TINYINT
SMALLINT Type
SMALLINT
Possible values: -32768 to 32767. Mapped to java.lang.Short. The binary representation is a 2 byte short with the sign bit flipped (so that negative values sort before positive values).
Example:
SMALLINT
UNSIGNED_SMALLINT Type
UNSIGNED_SMALLINT
Possible values: 0 to 32767. Mapped to java.lang.Short. The binary representation is an 2 byte integer, matching the HBase Bytes.toBytes(short) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_SMALLINT
FLOAT Type
FLOAT
Possible values: -3.402823466 E + 38 to 3.402823466 E + 38. Mapped to java.lang.Float. The binary representation is an 4 byte float with the sign bit flipped (so that negative values sort before positive values).
Example:
FLOAT
UNSIGNED_FLOAT Type
UNSIGNED_FLOAT
Possible values: 0 to 3.402823466 E + 38. Mapped to java.lang.Float. The binary representation is an 4 byte float matching the HBase Bytes.toBytes(float) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_FLOAT
DOUBLE Type
DOUBLE
Possible values: -1.7976931348623158 E + 308 to 1.7976931348623158 E + 308. Mapped to java.lang.Double. The binary representation is an 8 byte double with the sign bit flipped (so that negative values sort before positive value).
Example:
DOUBLE
UNSIGNED_DOUBLE Type
UNSIGNED_DOUBLE
Possible values: 0 to 1.7976931348623158 E + 308. Mapped to java.lang.Double. The binary representation is an 8 byte double matching the HBase Bytes.toBytes(double) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead.
Example:
UNSIGNED_DOUBLE
DECIMAL Type
DECIMAL
Data type with fixed precision and scale. The maximum precision is 18 digits. Mapped to java.math.BigDecimal. The binary representation is binary comparable, variable length format. When used in a row key, it is terminated with a null byte unless it is the last column.
Example:
DECIMAL
BOOLEAN Type
BOOLEAN
Possible values: TRUE and FALSE.
Mapped to java.lang.Boolean. The binary representation is a single byte with 0 for false and 1 for true
Example:
BOOLEAN
TIME Type
TIME
The time data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained. Mapped to java.sql.Time. The binary representation is an 8 byte long (the number of milliseconds from the epoch).
Example:
TIME
DATE Type
DATE
The date data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained to a millisecond accuracy. Mapped to java.sql.Date. The binary representation is an 8 byte long (the number of milliseconds from the epoch).
Example:
