XREVRANGE - Upstash Documentation

Use XREVRANGE to read the entries of a stream within a range of IDs, from the newest to the oldest. It is XRANGE in reverse, and the bounds are given in reverse too: <end> comes before <start>, so XREVRANGE key + - walks the whole stream backwards. Incomplete IDs are completed the same way, ( makes a bound exclusive, and COUNT limits the number of entries. XREVRANGE key + - COUNT 1 is the idiomatic way to read the most recent entry of a stream.

Syntax

XREVRANGE <key> <end> <start> [COUNT <count>]

Arguments

Argument	Required	Repeatable	Description
`<key>`	Yes	No	Redis key targeted by the command.
`<end>`	Yes	No	Last ID to return, scanning backwards; `-` means the smallest possible ID.
`<start>`	Yes	No	First ID to return, scanning backwards; `+` means the largest possible ID.
`COUNT <count>`	No	No	Maximum number of entries to return.

Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

Protocol	Reply
RESP2	Array of two-element entry arrays: ID and flat field/value array
RESP3	Array of two-element entry arrays: ID and flat field/value array

Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
