10.17. Atomic

Atomic procedures handle the concurrency, it’s add a lock to the resource. If two users access to the same resource at the same time, with the parameter times (default value 5) we can determine how many time retry to modify the resource, until the lock is release.

`CALL apoc.atomic.add(node/relationship, "property", number, [times]) YIELD oldValue, newValue`	adds the number to the value of the property
`CALL apoc.atomic.subtract(node/relationship, "property", number, [times]) YIELD oldValue, newValue`	subtracts the number to the value of the property
`CALL apoc.atomic.concat(node/relationship, "property", "string", [times]) YIELD oldValue, newValue`	concatenate the string to the property
`CALL apoc.atomic.insert(node/relationship, "property", position, object, [times]) YIELD oldValue, newValue`	inserts the object in the chosen position of the array
`CALL apoc.atomic.remove(node/relationship, "property", position, [times]) YIELD oldValue, newValue`	remove from the array the element to the position selected
`CALL apoc.atomic.update(node/relationship, "property", "expression", [times]) YIELD oldValue, newValue`	update the property with the result of the expression
