How much memory does SQLite use?

Question

SQLite will refuse to allocate more than about 2GB of memory at one go. (In common use, SQLite seldom ever allocates more than about 8KB of memory at a time so a 2GB allocation limit is not a burden.) So the 64-bit size parameter provides lots of headroom for detecting overflows.

How much space does SQLite take up?

The maximum size of a database file is 4294967294 pages. At the maximum page size of 65536 bytes, this translates into a maximum database size of approximately 1.4e+14 bytes (281 terabytes, or 256 tebibytes, or 281474 gigabytes or 256,000 gibibytes).

Is SQLite heavy?

An SQLite database is limited in size to 281 terabytes (248 bytes, 256 tibibytes). And even if it could handle larger databases, SQLite stores the entire database in a single disk file and many filesystems limit the maximum size of files to something less than this.

Is SQLite good for large data?

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.

Is SQLite faster than file?

Reading and writing from an SQLite database is often faster than reading and writing individual files from disk. See 35% Faster Than The Filesystem and Internal Versus External BLOBs. The application only has to load the data it needs, rather than reading the entire file and holding a complete parse in memory.
