JSON.MGET

Syntax
JSON.MGET key [key ...] path
Available in:
Redis Stack / JSON 1.0.0
Time complexity:
O(M*N) when path is evaluated to a single value where M is the number of keys and N is the size of the value, O(N1+N2+...+Nm) when path is evaluated to multiple values where m is the number of keys and Ni is the size of the i-th key

Returns the values at path from multiple key arguments. Returns null for nonexistent keys and nonexistent paths.

Return

Array reply of Bulk string reply - the JSON serialization of the value at each key's path.
