Redis State Store: numeric operators do not work correctly on large numbers due to formatting logic in Go

[gspadotto]

Expected Behavior

Define a numeric index on a Redis State Store (i.e. an index with a Timestamp attribute), then search with criteria that involve it.

The criteria should be correctly evaluated and applied.

Actual Behavior

When the numeric is larger than https://pkg.go.dev/fmt configured threshold, scientific notation is used to represent the number and comparisons do not work anymore in the generated Redis Query.

Steps to Reproduce the Problem

Create a Redis State Store with an index on a numeric attribute, as described here.

Then invoke the Query API on it with this template curl command:

curl -v --location 'http://localhost:3500/v1.0-alpha1/state/redis-state-store/query?metadata.contentType=application/json&metadata.queryIndexName=myRedisIndexName' \ --header 'Content-Type: application/json' \ --data '{ "filter": { "GT": { "header.timestamp": NUMBER_HERE } }, "page":{ "limit": 2 }, "sort":[ { "key":"header.timestamp", "order":"DESC" } ] }'
Connect to Redis with RedisCLI and launch the "MONITOR" command.

When NUMBER_HERE is 1.2 or 100000 you'll see the following outputs:

"FT.SEARCH" "rawEventsIndx" "@var1:[(1.2 +inf]" "SORTBY" "var1" "DESC" "LIMIT" "0" "2" "RETURN" "2" "$.data" "$.version"

"FT.SEARCH" "rawEventsIndx" "@var1:[(100000 +inf]" "SORTBY" "var1" "DESC" "LIMIT" "0" "2" "RETURN" "2" "$.data" "$.version"

and you get the correct results, but when NUMBER_HERE is 1000000, you get

"FT.SEARCH" "rawEventsIndx" "@var1:[(1e+06 +inf]" "SORTBY" "var1" "DESC" "LIMIT" "0" "2" "RETURN" "2" "$.data" "$.version"

and no result.

The solution might be (I do not know GoLang at all) in all occurrences of these lines:
https://github.com/dapr/components-contrib/blob/main/state/redis/redis_query.go#L107-L112

use "%d" as format specifier in the default branch and add a branch for float64, float32 types
that uses "%f" as format specifier.

Release Note

RELEASE NOTE: FIX Numeric operators on Redis State Store query API.
