Valkey Roaring

Appearance

R.SETFULL / R64.SETFULL ​

Creates the key with every possible bit set.

SyntaxR.SETFULL key
64-bitR64.SETFULL key
Time complexityO(65,536) containers for 32-bit

Arguments ​

  • key — must not already exist

Reply ​

Simple string OK; an existing key is an error.

Notes ​

  • R.SETFULL stores 2³² values as 65,536 run containers (about 3 MB). It is refused when valkey-roaring.max-write-values is set below 4294967296, and, with maxmemory set, when those 3 MB would push used memory past it (see limits).
  • R64.SETFULL is always refused, with Roaring: range too large: maximum 274877906944 elements by default: the full 64-bit space would need 2³² full 32-bit sub-bitmaps (2⁴⁸ containers), far more than any server holds. Use R64.SETRANGE over the range you actually need.

Example ​

bash
127.0.0.1:6379> R.SETFULL k
OK
127.0.0.1:6379> R.BITCOUNT k
(integer) 4294967296
