Does this skill support SQLite's STRICT mode?

Yes, it prioritizes the use of STRICT tables to ensure rigid data typing and better data integrity, which is a modern SQLite best practice.

Does it help with database concurrency?

Yes, it utilizes 'BEGIN IMMEDIATE' transactions and appropriate busy timeouts to manage multi-connection environments and prevent database locking issues.

How does this skill improve SQLite performance?

It configures optimized PRAGMA settings like Write-Ahead Logging (WAL), increased cache sizes, and synchronous normal modes to significantly boost read/write speeds.

How does it handle large data imports?

The skill follows a specific pattern: creating tables first, inserting data in large transactions (10k+ rows), and then creating indices at the end to maximize efficiency.
