R64.BITOP
| Category | Description |
|---|---|
| Syntax | R64.BITOP <AND, OR, XOR, NOT, ANDOR, ONE> destkey key [key1 key2 ... keyN] |
| Time complexity | O(C) |
| Supports structures | Bitmap64 |
| Command description | Performs set operations on Roaring Bitmaps and stores the result in destkey. |
Parameter
- operation: The type of set operation.
- destkey: The destination key that stores the result (Roaring data structure).
- key: The key of the Roaring data structure. You can specify multiple keys.
Output
- If the operation is successful, the big number of bits in the result that are set to 1 is returned.
- Otherwise, an error message is returned.
Examples
Basic Usage
$ redis-cli
127.0.0.1:6379> R64.BITOP OR destkey srckey1 srckey2 srckey3
"6"Usage Notes
- Empty source keys are automatically skipped during the bitwise operation
- All keys must be of the same Roaring bitmap type (Bitmap64)
- The operation creates the destination key if it doesn't exist
- To properly handle bigint values, use RESP3 protocol; otherwise the result will be returned as a string
