trait insert extends AnyRef

Insert one or more rows of data matching molecule.

Insert one or more rows of data matching molecule.

Returns Future with TxReport having info about the result of the insert transaction.

Data matching the types of the molecule can be inserted either as individual args or an Iterable (List, Set etc) of tuples:

// Insert single row of data with individual args
Person.name.age.insert("Ann", 28)

// Insert multiple rows of data. Accepts Iterable[Tpl]
Person.name.age insert List(
  ("Ben", 42),
  ("Liz", 37)
)

// Data was inserted
Person.name.age.get.sorted === List(
  ("Ann", 28),
  ("Ben", 42),
  ("Liz", 37)
)

Each insert apply method returns a TxReport with info about the result of the transaction.

Since insert is an object of each arity 1-22 Molecule implementation, we can make an "insert-molecule" at compile time that we can re-use for inserting data at runtime matching the molecule type:

// At compiletime:

// Make insert-molecule
val insertPersonsWithAge = Person.name.age.insert

// At runtime:

// Apply individual args matching insert-molecule to insert single row
insertPersonsWithAge("Ann", 28)

// .. or apply Iterable of tuples matching insert-molecule to insert multiple rows
insertPersonsWithAge(
  List(
    ("Ben", 42),
    ("Liz", 37)
  )
)

// Data was inserted
Person.name.age.get.sorted === List(
  ("Ann", 28),
  ("Ben", 42),
  ("Liz", 37)
)

The insert operation is synchronous and blocking. Use insertAsync for non-blocking asynchronous inserts.

Definition Classes: Molecule

trait insertAsync extends AnyRef

Asynchronously insert one or more rows of data matching molecule.

Asynchronously insert one or more rows of data matching molecule.

Returns Future with TxReport having info about the result of the insert transaction.

Data matching the types of the molecule can be inserted either as individual args or an Iterable (List, Set etc) of tuples:

// Insert single row of data with individual args
val singleInsertFuture: Future[TxReport] = Person.name.age.insertAsync("Ann", 28)

// Insert multiple rows of data. Accepts Iterable[Tpl]
val multipleInsertFuture: Future[TxReport] = Person.name.age insertAsync List(
  ("Ben", 42),
  ("Liz", 37)
)

for {
  _ <- singleInsertFuture
  _ <- multipleInsertFuture
  result <- Person.name.age.getAsync
} yield {
  // Both inserts applied
  result === List(
    ("Ann", 28),
    ("Ben", 42),
    ("Liz", 37)
  )
}

The insert operation is asynchronous and non-blocking. Internally calls Datomic's asynchronous API.

def getArraySince(t: Long, n: Int)(implicit conn: Conn, tplType: ClassTag[(A, B, C, D)]): Array[(A, B, C, D)]
Get Array of n rows as tuples matching molecule since transaction time t.
Get Array of n rows as tuples matching molecule since transaction time t.

Transaction time t is an auto-incremented transaction number assigned internally by Datomic.

t can for instance be retrieved by calling t on the tx report returned from transactional operations and then be used to get data since that point in time (excluding that transaction):
```
// 3 transaction times `t`
val t1 = Person.name("Ann").save.t
val t2 = Person.name("Ben").save.t
val t3 = Person.name("Cay").save.t

// Current values
Person.name.get === List("Ann", "Ben", "Cay")

// Ben and Cay added since transaction time t 1028
Person.name.getArraySince(t1) === Array("Ben", "Cay")

// Ben and Cay added since transaction time t 1028 - only n (1) rows returned
Person.name.getArraySince(t1, 1) === Array("Ben")
```

def getIterableAsOf(t: Long)(implicit conn: Conn): Iterable[(A, B, C, D)]

Get Iterable of all rows as tuples matching molecule as of transaction time t.

Get Iterable of all rows as tuples matching molecule as of transaction time t.

Transaction time t is an auto-incremented transaction number assigned internally by Datomic.

Call getIterableAsOf for large result sets to maximize runtime performance. Data is lazily type-casted on each call to next on the iterator.

t can for instance be retrieved in a getHistory call for an attribute and then be used to get data as of that point in time (including that transaction):

// Insert (t 1028)
val List(ben, liz) = Person.name.age insert List(
  ("Ben", 42),
  ("Liz", 37)
) eids

// Update (t 1031)

Datomic's internal since method can take a transaction entity id as argument to retrieve a database value since that transaction (excluding the transaction itself).

def getSince(tx: TxReport, n: Int)(implicit conn: Conn): List[(A, B, C, D)]
Get List of n rows as tuples matching molecule since tx.
Get List of n rows as tuples matching molecule since tx.

Datomic's internal since can take a transaction entity id as argument to retrieve a database value since that transaction (excluding the transaction itself).

Instead of supplying the transaction entity id, in Molecule we supply a TxReport that contains the transaction entity id (which is used as argument to Datomic internally). This is more convenient when using Molecule since we getAsync a TxReport from transaction operations like get, update, retract etc.
```
// Get tx reports for 3 transactions
val tx1 = Person.name("Ann").save
val tx2 = Person.name("Ben").save
val tx3 = Person.name("Cay").save

// Current values
Person.name.get === List("Ann", "Ben", "Cay")
