Question

android sqlite wal 一般多大

Answer 1

很明显android上的SQLite数据库是放不下2TB的数据

Answer 2

ublic boolean enableWriteAheadLogging() {
// make sure the database is not READONLY. WAL doesn't make sense for readonly-databases.
if (isReadOnly()) {
return false;
}
// acquire lock - no that no other thread is enabling WAL at the same time
lock();
try {
if (mConnectionPool != null) {
// already enabled
return true;
}
if (mPath.equalsIgnoreCase(MEMORY_DB_PATH)) {
Log.i(TAG, "can't enable WAL for memory databases.");
return false;
}
