`static String`	`SHARD_KEY` This property indicates that this column will be part of (or the entire) shard key.
`static String`	`STORE_ONLY` Persist the column value but do not make it available to queries (e.g.
`static String`	`TEXT_SEARCH` Valid only for 'string' columns.
`static String`	`TIMESTAMP` Valid only for 'long' columns.

  - DATA
```
public static final String DATA
```
    Default property for all numeric and string type columns; makes the column available for GPU queries.

    Constant Field Values
  - TEXT_SEARCH
```
public static final String TEXT_SEARCH
```
    Valid only for 'string' columns. Enables full text search for string columns. Can be set independently of *data* and *store_only*.
    
    See Also:
    
    Constant Field Values
  - STORE_ONLY
```
public static final String STORE_ONLY
```
    Persist the column value but do not make it available to queries (e.g. GPUdb.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.
    
    See Also:
    
    Constant Field Values
  - DISK_OPTIMIZED
```
public static final String 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 GPUdb.filter(FilterRequest), GPUdb.filterByList(FilterByListRequest), and GPUdb.filterByValue(FilterByValueRequest) work as usual but GPUdb.aggregateUniqueRaw(AggregateUniqueRequest), GPUdb.aggregateGroupByRaw(AggregateGroupByRequest) and GPUdb.getRecordsByColumnRaw(GetRecordsByColumnRequest) are not allowed on columns with this property.
    
    See Also:
    
    Constant Field Values
  - TIMESTAMP
```
public static final String 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.
    
    See Also:
    
    Constant Field Values
  - CHAR1
```
public static final String CHAR1
```
    This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 1 character. This property cannot be combined with *text_search*
    
    See Also:
    
    Constant Field Values
  - CHAR2
```
public static final String CHAR2
```
    This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 2 characters. This property cannot be combined with *text_search*
    
    See Also:
    
    Constant Field Values
  - CHAR4
```
public static final String CHAR4
```
    This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 4 characters. This property cannot be combined with *text_search*
