About
This exercise is from the section "Data Structures That Power Your Database" from the book Designing Data-Intensive Applications. It is meant to illustrate an append-only log.
How to use
In your terminal, run the following to load functions
from the file log-structured-storage.
source log-structured-storage.sh
The following functions are available:
db_set <key> <value>
db_get <key>
The data is stored in the database file. Key-value
pairs are separated by comma, and each pair is on
its own line.
Examples
db_set 42 '{"name":"San Francisco","attractions":["Golden Gate Bridge"]}'
db_get 42
{"name":"San Francisco","attractions":["Golden Gate Bridge"]}
