Can multiple processes access SQLite?
SQLite allows multiple processes to have the database file open at once, and for multiple processes to read the database at once. When any process wants to write, it must lock the entire database file for the duration of its update. But that normally only takes a few milliseconds.
How many concurrent connections can SQLite handle?
The default limit is 1,024.
Does SQLite3 support concurrency?
SQLite does support multiple concurrent connections, and therefore it can be used with a multi-threaded or multi-process application. The catch is that when SQLite opens a write transaction, it will lock all the tables.
Can SQLite handle concurrent writes?
Overview. Usually, SQLite allows at most one writer to proceed concurrently. The BEGIN CONCURRENT enhancement allows multiple writers to process write transactions simultanously if the database is in "wal" or "wal2" mode, although the system still serializes COMMIT commands.
