LS3 is a local implementation of an block based storage API coined Local Simple Storage Solution
LS3 offers a command line utility for inserting new key value pairs, retrieving them, and deleting them.
- put
ls3 putis a command that takes two arguments maximum: key [string], value [string]. this command puts the specified key value pair into storage. This command also has a-fflag that allow users to upload a file and its contents. In that case, the command only takes one argument.- ex:
ls3 put 123 testing - ex:
ls3 put -f testing.txt
- get
ls3 getis a command that takes a single argument of the key [string] to be retrieved from storage. This command returns the data from the given key.- ex:
ls3 get 123
- delete
ls3 deleteis a command that takes one argument: key [string] and deletes that key from object storage if it exists.- ex:
ls3 delete 123
The below table represents some basi operations and their times as of December 2022.
| Number of Keys | Number of Insertions | Number of Retrievals | Number of Deletions | Number of Operations | Overall Time |
|---|---|---|---|---|---|
| 100 | 100 | 100 | 50 | 350 | 3.99 Sec |
| 1000 | 1000 | 1000 | 500 | 3500 | 6.003 Sec |
| 3000 | 3000 | 3000 | 1500 | 10500 | 28.361 Sec |

- implement
ls3 list - define a FS type for mounting the datafile so it is registered with the Kernel.
- Register a FS type for usage with an external drive
ls3 formatcommand to make a file the proper type so the kernel recognizes it.- support for partial gets (only a certain amount of bytes)
- support for concurrency
- coalescing holes within storage and which holes to pick -- currently we pick the last hole
- remove dependency on non file based arrays
- make docs
- performance statistics (table)
- caching of data
- disk layout / index management (table?)
- add commands that can connect to remote object storage.
- add memory awareness
