README
Nuummite 
Nuummite is a tiny persistent embedded key-value store. All data is kept in RAM (in a Crystal Hash) and is also written to disk. So don't use Nuummite to handle big chunks of data. Keys and Values are always Strings. It just comes with the most basic operations.
Installation
Add this to your application's shard.yml:
dependencies:
nuummite:
github: codesteak/nuummite
version: ~> 0.1.4
Usage
require "nuummite"
Open the database
db = Nuummite.new("path/to/folder", "optional-filename.db")
# You can also have multiple:
flowers = Nuummite.new("flowers")
minerals = Nuummite.new("minerals")
Put some values in
db["hello"] = "world"
db["42"] = "Answer to the Ultimate Question of Life, The Universe, and Everything"
db["whitespace"] = "Hey\n\t\t :D"
Read values
db["hello"]? # => "world"
db["ehhhh"]? # => nil
#Note: db is locked while reading, so don't write to db!
db.each do |key,value|
# reads everything
end
db["crystals/ruby"] = "9.0"
db["crystals/quartz"] = "~ 7.0"
db["crystals/nuummite"] = "5.5 - 6.0"
db.each("crystals/") do |key,value|
# only crystals in here
end
Delete
db.delete "hello"
Garbage collect
Since values are saved to disk in a log style, file sizes grow, your key-value store needs to rewrite all data at some point:
db.garbage_collect
By default it auto garbage collects after 10_000_000 writes. To modify this behavior you can:
# garbage collects after 1000 writes or deletes
db.auto_garbage_collect_after_writes = 1000
# does not auto garbage collect
db.auto_garbage_collect_after_writes = nil
Shutdown
You can also shutdown Nuummite by
db.shutdown
That's all you need to know :smile:
