How do I limit the size of a SQLite database?

The maximum number of attached databases can be lowered at run-time using the sqlite3_limit(db,SQLITE_LIMIT_ATTACHED,size) interface. SQLite is able to limit the size of a database file to prevent the database file from growing too large and consuming too much disk space.

What is the maximum size of database file?

The maximum size of a database file is 2147483646 pages. At the maximum page size of 65536 bytes, this translates into a maximum database size of approximately 1.4e+14 bytes (140 terabytes, or 128 tebibytes, or 140,000 gigabytes or 128,000 gibibytes).

Can you compress an SQLite database?

SQLite’s FTS4 extension provides a compression option: sqlite.org/fts3.html#section_6_1. However, that extension is apparently only present in Android since API level 11 (see here: stackoverflow.com/questions/6339022/…). Alternatively you could do compression / decompression in Java.

Is SQLite good for large data?

Practically sqlite is likely to work as long as there is storage available. It works well with dataset larger than memory, it was originally created when memory was thin and it was a very important point from the start. There is absolutely no issue with storing 100 GB of data.

What is limitation of SQLite?

SQLite can have a maximum database size of 140 terabytes (TB). A SQLite database is a set of one more pages where every page is the same size. Maximum size of a page cannot exceed 65536 bytes. The maximum size of a database file is 2147483646 pages.

Is SQLite faster than SQL Server?

SQLite is generally a lot faster than SQL Server. However, SQLite only supports a single writer at a time (meaning the execution of an individual transaction). SQLite locks the entire database when it needs a lock (either read or write) and only one writer can hold a write lock at a time.

What is the max size of MySQL database?

What’s the maximum MySQL database size allowed? At 20i, each MySQL database you create can store up to 1024 MB (1 GB) of data. As databases comprise of only text, this is a lot of space in real terms; to put it into perspective, a 20i customer’s average database size is just 10 MB.

How do you VACUUM a SQLite database?

The VACUUM command works by copying the contents of the database into a temporary database file and then overwriting the original with the contents of the temporary file. When overwriting the original, a rollback journal or write-ahead log WAL file is used just as it would be for any other database transaction.

How do I truncate a table in SQLite?

SQLite does not have an explicit TRUNCATE TABLE command like other databases. Instead, it has added a TRUNCATE optimizer to the DELETE statement. To truncate a table in SQLite, you just need to execute a DELETE statement without a WHERE clause. The TRUNCATE optimizer handles the rest.

Why is SQLite so slow?

The SQLite docs explains why this is so slow: Transaction speed is limited by disk drive speed because (by default) SQLite actually waits until the data really is safely stored on the disk surface before the transaction is complete. That way, if you suddenly lose power or if your OS crashes, your data is still safe.

Is SQLite obsolete?

The browsers Google Chrome, Opera, Safari and the Android Browser all allow for storing information in, and retrieving it from, a SQLite database within the browser, using the Web SQL Database technology, although this is rapidly becoming deprecated (namely superseded by IndexedDB).
