Interface Summary

Interface	Description
DmlArgument	DML argument

Class Summary

Class	Description
DmlArguments	DML arguments factory.
DmlAstUtils	AST utils for DML
DmlBatchSender	Batch sender class.
DmlBulkLoadDataConverter	Converts a row of values to actual key+value using UpdatePlan.processRow(List).
DmlDistributedPlanInfo	Additional information about distributed update plan.
DmlDistributedUpdateRun	Context for DML operation on reducer node.
DmlPageProcessingErrorResult	Result of splitting keys whose processing resulted into an exception from those skipped by logic of EntryProcessors (most likely INSERT duplicates, or UPDATE/DELETE keys whose values had been modified concurrently), counting and collecting entry processor exceptions.
DmlPageProcessingResult	Result of processing an individual page with IgniteCache.invokeAll(java.util.Map<? extends K, ? extends javax.cache.processor.EntryProcessor<K, V, T>>, java.lang.Object...) including error details, if any.
DmlUtils	DML utility methods.
FastUpdate	Arguments for fast, query-less UPDATE or DELETE - key and, optionally, value and new value.
UpdatePlan	Update plan - where to take data to update cache from and how to construct new keys and values, if needed.
UpdatePlanBuilder	Logic for building update plans performed by DmlStatementsProcessor.
