Arguments

string
The cursor value. Start with “0” on the first call, then use the cursor returned by each call for the next. It’s a string to safely support large numbers that might exceed JavaScript’s number limits.
Object
string
Glob-style pattern to filter by field names.
number
Number of fields to return per call.
string
Filter by type. For example string, hash, set, zset, list, stream.
