A simple database system over telnet with TLS (using OpenSSL).
Make sure you have check installed. Make sure you have Valgrind installed.
Only builds for linux.
The db will support the following commands:
- get
- store
- delete
- search <key_prefix>
Each command will be built to support new operations.
We support very limited keys at this time for simplicity. Keys have the following limitations:
Supported Characters - [0-9] Max Length - 512 Min Length - 1
Example key:
84930246732898439230
Any data, but we don't capture data types. We store the data as raw bytes for now and return the data in the same format. Since this is over telnet, the data is effectively a string. It's up to the consumer to handle deserialization.
We do have a maximum size of 4KB (4 * 1024 bytes) per value.
Below is a list of the support operations with in-depth details
Returns a single value for the specified key.
If no key is found the value sent back will be
nil.
get <key> -> <value>
Where
key - A key
value - A blob of contiguous binary data
Stores the specified value at the specified key. Acts as an upsert in that it will create or overwrite the data at the specified key.
store <key> <value> -> <ok|error>
Where
key - The key used to store the value
value - The value to store
ok|error - Response status codes. ok means the value was stored properly. error signals some storage error.
Deletes the value stored at a specified key. If no value exists this is essentially a no-op.
delete <key> -> <ok|error>
Where
key - The key used to identify the value to delete
ok|error - Response status codes. ok means the value was deleted or no-op. error signals some delete error.
Searches for a key prefix and returns all values nested under the prefix.
If no values are found, returns [].
select <key_prefix> -> [<value>]
Where
key_prefix - Similar to a key, but represents a path to search for all nested values.
[<value>] - An array of values found nested under the specific search key prefix.
