ICSQLite is a cloud SQLite database on Internet Computer and provides SDK for developers to use.
Our goal is to help developers quickly migrate web2 applications to Internet Computer.
In your Cargo.toml:
[dependencies]
ic-sqlite = "0.1.0"Limited by the total number of cycles of a call, if the number of rows retrieved by a single SQL query exceeds a certain amount, the call will crash.
- Strictly follow the rules of database optimization
- Index building must be an empty table
- Where query must be filtered for primary key or index field
- Less use NOT,!=,<>,!<,!> NOT EXISTS, NOT IN, NOT LIKE, OR, they will ignore the index and cause a full table scan
