Definition at line 87 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.CHAR64 = "char64" |
This property provides optimized memory, disk and query performance for string columns.
Strings with this property must be no longer than 64 characters. This property cannot be combined with text_search
Definition at line 111 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.CHAR8 = "char8" |
This property provides optimized memory, disk and query performance for string columns.
Strings with this property must be no longer than 8 characters. This property cannot be combined with text_search
Definition at line 93 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.DATA = "data" |
Default property for all numeric and string type columns; makes the column available for GPU queries.
Definition at line 17 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.DATE = "date" |
Valid only for 'string' columns.
Indicates that this field represents a date and will be provided in the format 'YYYY-MM-DD'. The allowable range is 1000-01-01 through 2900-01-01.
Definition at line 63 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.DECIMAL = "decimal" |
Valid only for 'string' columns.
It represents a SQL type NUMERIC(19, 4) data type. There can be up to 15 digits before the decimal point and up to four digits in the fractional part. The value can be positive or negative (indicated by a minus sign at the beginning). This property is mutually exclusive with the 'text_search' property.
Definition at line 57 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.DISK_OPTIMIZED = "disk_optimized" |
Works in conjunction with the 'data' property for string columns.
This property reduces system disk usage by disabling reverse string lookups. Queries like Kinetica.filter(FilterRequest), Kinetica.filterByList(FilterByListRequest), and Kinetica.filterByValue(FilterByValueRequest) work as usual but Kinetica.aggregateUnique(AggregateUniqueRequest), Kinetica.aggregateGroupBy(AggregateGroupByRequest) and Kinetica.getRecordsByColumn(GetRecordsByColumnRequest) are not allowed on columns with this property.
Definition at line 42 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.INT16 = "int16" |
This property provides optimized memory and query performance for int columns.
Ints with this property must be between -32768 and +32767 (inclusive)
Definition at line 133 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.INT8 = "int8" |
This property provides optimized memory and query performance for int columns.
Ints with this property must be between -128 and +127 (inclusive)
Definition at line 128 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.IPV4 = "ipv4" |
This property provides optimized memory, disk and query performance for string columns representing IPv4 addresses (i.e.
192.168.1.1). Strings with this property must be of the form: A.B.C.D where A, B, C and D are in the range of 0-255.
Definition at line 139 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.NULLABLE = "nullable" |
This property indicates that this column is nullable.
However, setting this property is insufficient for making the column nullable. The user must declare the type of the column as a union between its regular type and 'null' in the avro schema for the record type in <member name="type_definition">. For example, if a column is of type integer and is nullable, then the entry for the column in the avro schema must be: ['int', 'null'].
The Java and C++ APIs have built-in convenience for bypassing setting the avro schema by hand. For those two languages, one can use this property as usual and not have to worry about the avro schema for the record.
Definition at line 161 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.PRIMARY_KEY = "primary_key" |
This property indicates that this column will be part of (or the entire) primary key.
Definition at line 143 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.SHARD_KEY = "shard_key" |
This property indicates that this column will be part of (or the entire) shard key.
Definition at line 147 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.STORE_ONLY = "store_only" |
Persist the column value but do not make it available to queries (e.g.
Kinetica.filterByBox(FilterByBoxRequest))-i.e. it is mutually exclusive to the 'data' property. Any 'bytes' type column must have a 'store_only' property. This property reduces system memory usage.
Definition at line 29 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.TEXT_SEARCH = "text_search" |
Valid only for 'string' columns.
Enables full text search for string columns. Can be set independently of data and store_only.
Definition at line 22 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.TIME = "time" |
Valid only for 'string' columns.
Indicates that this field represents a time-of-day and will be provided in the format 'HH:MM:SS.mmm'. The allowable range is 00:00:00.000 through 23:59:59.999.
Definition at line 69 of file ColumnProperty.cs.
| const string kinetica.ColumnProperty.TIMESTAMP = "timestamp" |
Valid only for 'long' columns.
Indicates that this field represents a timestamp and will be provided in milliseconds since the Unix epoch: 00:00:00 Jan 1 1970. Dates represented by a timestamp must fall between the year 1000 and the year 2900.
