Hi,
I am using FastBit JNI to build indexes. I have a problem when I try to build
indexes of both integer and text columns. Here is the process to reproduce the
problem:
= Load an integral column with FastBit.add_longs() and FastBit.write_buffer().
= Load a text column with FastBitStringWriter.addText() and
FastBitStringWriter.addStringColumnToMetadata()
= At this time, the -part.txt is correctly constructed for the two columns.
= Then I run FastBit.build_indexes(). Only the intergral column has an index.
The -part.txt file now only contains the metadata for the intergral column.
Is this the right way to build indexes on a mix of integral and text columns?
I paste the code here:
import gov.lbl.fastbit.FastBit;
import gov.lbl.fastbit.FastBitStringWriter;
import gov.lbl.fastbit.FastBitStringWriterException;
public class FastBitTest {
public static void main(String args[]) throws FastBitStringWriterException
{
String[] strArr = {"0", "1", "2", "3"};
long[] intArr = {4, 5, 6, 7};
String partName = "/path/to/the/data/folder";
FastBit fb = new FastBit(null);
FastBitStringWriter writer = new FastBitStringWriter();
fb.add_longs("long", intArr);
fb.write_buffer(partName);
writer.addText(partName, "str", strArr, "UTF-8");
writer.addStringColumnToMetadata(partName, "str", "text");
fb.build_indexes(partName, "basic");
}
}
Cheers,
Bailu
