R.OPTIMIZE / R64.OPTIMIZE

Re-chooses container representations for the current data, improving compression, and releases the spare capacity incremental writes leave behind when it is worth a copy (at least an eighth of the value's memory, and 64 bytes per container on average).

Syntax	R.OPTIMIZE key
64-bit	R64.OPTIMIZE key
Time complexity	O(N)

Arguments

• key — the bitmap key

Reply

Simple string OK. A missing key is an error (Roaring: key does not exist). An optional third argument (such as MEM) is accepted and changes nothing.

Notes

• R.EXPORT optimizes automatically before serializing (without releasing spare capacity).

Example

127.0.0.1:6379> R.OPTIMIZE k
