Is SQLite stored in RAM?

Question

An SQLite database is normally stored in a single ordinary disk file. However, in certain circumstances, the database might be stored in memory. The most common way to force an SQLite database to exist purely in memory is to open the database using the special filename ":memory:".

Does SQLite use RAM?

SQLite uses dynamic memory allocation to obtain memory for storing various objects (ex: database connections and prepared statements) and to build a memory cache of the database file and to hold the results of queries.

How is SQLite data stored?

The Android SDK provides dedicated APIs that allow developers to use SQLite databases in their applications. The SQLite files are generally stored on the internal storage under /data/data//databases. However, there are no restrictions on creating databases elsewhere.

Are databases stored in RAM?

An in-memory database keeps all its data in the random access memory (RAM) of a computer. Only the main memory is accessed when querying data. This allows for faster access of that data than a disk-based system.

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).
