Method: Cequel::Metal::Batch#initialize

Defined in:
lib/cequel/metal/batch.rb

#initialize(keyspace, options = {}) ⇒ Batch

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a new instance of Batch.

Parameters:

  • keyspace (Keyspace) —

    the keyspace that this batch will be executed on

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :auto_apply (Integer) —

    If specified, flush the batch after this many statements have been added.

  • :unlogged (Boolean) — default: false —

    Whether to use an [unlogged batch]( www.datastax.com/dev/blog/atomic-batches-in-cassandra-1-2). Logged batches guarantee atomicity (but not isolation) at the cost of a performance penalty; unlogged batches are useful for bulk write operations but behave the same as discrete writes.
