Method Detail

addRowsToBuffer

void addRowsToBuffer(java.util.List<Row> rows,
                     java.lang.String bufferName)

Add the rows to a temporary storage (not to the index yet). The rows are sorted by the index columns. This is to more quickly build the index.

Parameters:

rows - the rows

bufferName - the name of the temporary storage

addBufferedRows

void addBufferedRows(java.util.List<java.lang.String> bufferNames)

Add all the index data from the buffers to the index. The index will typically use merge sort to add the data more quickly in sorted order.

Parameters:

bufferNames - the names of the temporary storage
