Description copied from interface: RegionObserver

This will be called for every batch mutation operation happening at the server. This will be called after acquiring the locks on the mutating rows and after applying the proper timestamp for each Mutation at the server. The batch may contain Put/Delete/Increment/Append. By setting OperationStatus of Mutations (MiniBatchOperationInProgress.setOperationStatus(int, OperationStatus)), RegionObserver can make Region to skip these Mutations.

Note: Do not retain references to any Cells in Mutations beyond the life of this invocation. If need a Cell reference for later use, copy the cell and use that.

Specified by:

preBatchMutate in interface RegionObserver

Parameters:

c - the environment provided by the region server

miniBatchOp - batch of Mutations getting applied to region.

Throws:

IOException

ctx - the environment provided by the region server

delete - - the parent mutation associated with this delete cell
