### setIdleConnectionTimeout
Added in [API level 27](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
Deprecated in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun setIdleConnectionTimeout(idleConnectionTimeoutMs: Long): SQLiteDatabase.OpenParams.Builder
```
**Deprecated:** *DO NOT USE this method. See the javadoc for the details.*
Sets the maximum number of milliseconds that SQLite connection is allowed to be idle before it is closed and removed from the pool.
**DO NOT USE** this method. This feature has negative side effects that are very hard to foresee.
A connection timeout allows the system to internally close a connection to a SQLite database after a given timeout, which is good for reducing app's memory consumption. **However** the side effect is it **will reset all of SQLite's per-connection states** , which are typically modified with a `PRAGMA` statement, and these states **will not be restored** when a connection is re-established internally, and the system does not provide a callback for an app to reconfigure a connection. This feature may only be used if an app relies on none of such per-connection states.
| Parameters ||
|---------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `idleConnectionTimeoutMs` | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html): timeout in milliseconds. Use [Long.MAX_VALUE](https://developer.android.com/reference/kotlin/java/lang/Long.html#MAX_VALUE:kotlin.Long) to allow unlimited idle connections. Value is 0 or greater |
| Return ||
|------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------|
| [SQLiteDatabase.OpenParams.Builder](https://developer.android.com/reference/kotlin/android/database/sqlite/SQLiteDatabase.OpenParams.Builder#) | This value cannot be `null`. |

fun setJournalMode(journalMode: String): SQLiteDatabase.OpenParams.Builder

### setLookasideConfig
Added in [API level 27](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun setLookasideConfig(
slotSize: Int,
slotCount: Int
): SQLiteDatabase.OpenParams.Builder!
```
Configures [lookaside memory allocator](https://sqlite.org/malloc.html#lookaside)
SQLite default settings will be used, if this method isn't called. Use `setLookasideConfig(0,0)` to disable lookaside
**Note:** Provided slotSize/slotCount configuration is just a recommendation. The system may choose different values depending on a device, e.g. lookaside allocations can be disabled on low-RAM devices
| Parameters ||
