Specified by:

setBulkLoad in interface TableDescriptor

Parameters:

bulkLoad - true if the bulk load mode is to be turned on

Returns:

this for chain invocation

isAutoSplit

public boolean isAutoSplit()

Specified by:

isAutoSplit in interface TableDescriptor

Returns:

true if a tablet should split automatically if it grows beyond a certain size.

setAutoSplit

public TableDescriptorImpl setAutoSplit(boolean autoSplit)

Description copied from interface: TableDescriptor

Sets the tablets to split automatically, or not, if they grow beyond a certain size.

Specified by:

setAutoSplit in interface TableDescriptor

Parameters:

autoSplit - true if the split should happen automatically

Returns:

this for chain invocation

getSplitSize

public long getSplitSize()

Specified by:

getSplitSize in interface TableDescriptor
