It does this by opening multiple connections to the database - * and using a different database connection for each query. The database - * journal mode is also changed to enable writes to proceed concurrently with reads. - *

- * When write-ahead logging is not enabled (the default), it is not possible for - * reads and writes to occur on the database at the same time. Before modifying the - * database, the writer implicitly acquires an exclusive lock on the database which - * prevents readers from accessing the database until the write is completed. - *

- * In contrast, when write-ahead logging is enabled (by calling this method), write - * operations occur in a separate log file which allows reads to proceed concurrently. - * While a write is in progress, readers on other threads will perceive the state - * of the database as it was before the write began. When the write completes, readers - * on other threads will then perceive the new state of the database. - *

- * It is a good idea to enable write-ahead logging whenever a database will be - * concurrently accessed and modified by multiple threads at the same time. - * However, write-ahead logging uses significantly more memory than ordinary - * journaling because there are multiple connections to the same database. - * So if a database will only be used by a single thread, or if optimizing - * concurrency is not very important, then write-ahead logging should be disabled. - *

- * After calling this method, execution of queries in parallel is enabled as long as - * the database remains open. To disable execution of queries in parallel, either - * call {@link #disableWriteAheadLogging} or close the database and reopen it. - *

- * The maximum number of connections used to execute queries in parallel is - * dependent upon the device memory and possibly other properties. - *

- * If a query is part of a transaction, then it is executed on the same database handle the - * transaction was begun. - *

- * Writers should use {@link #beginTransactionNonExclusive()} or - * {@link #beginTransactionWithListenerNonExclusive(TransactionObserver)} - * to start a transaction. Non-exclusive mode allows database file to be in readable - * by other threads executing queries. - *

- * If the database has any attached databases, then execution of queries in parallel is NOT - * possible. Likewise, write-ahead logging is not supported for read-only databases - * or memory databases. In such cases, {@code enableWriteAheadLogging} returns false. - *

- * The best way to enable write-ahead logging is to pass the - * {@link SQLiteDatabase#ENABLE_WRITE_AHEAD_LOGGING} flag to - * {@link SQLiteDatabase#openDatabase}. This is more efficient than calling - *
