An SQLite database is normally stored in a single ordinary disk file. However, in certain circumstances, the database might be stored in memory. Every :memory: database is distinct from every other. So, opening two database connections each with the filename ":memory:" will create two independent in-memory databases.

Additionally, is SQLite good enough? 3 Answers. It's a great way to get started and it can even work in lightly loaded environments, but it will not scale very well in a read/write environment. The good news is that switching to a full RDBMS like MySQL or Postgres is usually very straightforward. Good enough for what.

Herein, how much data can SQLite hold?

SQLite database files have a maximum size of about 140 TB. On a phone, the size of the storage (a few GB) will limit your database file size, while the memory size will limit how much data you can retrieve from a query. Furthermore, Android cursors have a limit of 1 MB for the results.

How many tablets can SQLite handle?

Maximum Number Of Tables In A Join SQLite does not support joins containing more than 64 tables. This limit arises from the fact that the SQLite code generator uses bitmaps with one bit per join-table in the query optimizer.
