Echo

An in-memory cache datastore written with Deno.

Disclaimer

This is currently beta software, and definitely not tested in a production sense. The road to Release Candidate isn't far off but it does require testing and benchmarking. Make sure to check out https://github.com/RedactedProfile/Echo and watch for the progress.

Usage

Check if a key exists

CHK mykey

Create / Update Key

The value doesn't have to be wrapped in quotes, but if your value contains any spaces it will need them

SET mykey keyvalue
SET mykey "key value"

Create / Update Key with a TTL

This is a convenience feature to negate the need for sending a follow up command

SET mykey "keyvalue" 1200

Set / Update an existing key's TTL (Time to Live)

TTL mykey 1600

Get / Retrieve Key value (if exists)

GET mykey

Delete / Remove a key

DEL mykey

Search for a key by name using greedy wildcards.

Returns a JSON string array of discovered key names

# Prefix search
KEY mykey*

# Suffix Search
KEY *mykey

# Fuzzy Search
KEY *mykey*

Search for a key by value

FND "search value"

Nuke all keys
