I have done with bulk loader with key_validation_class=LexicalUUIDType for new row with the help of this code but i have changed my key_validation_class=AsciiType or key_validation_class=UTF8Type in order to make string as row keys
create column family Users1
with key_validation_class=AsciiType
and comparator=AsciiType
AND column_metadata = [
{column_name: timestamp1, validation_class: AsciiType}
{column_name: symbol, validation_class: AsciiType}
{column_name: Bid_Price, validation_class:AsciiType}
{column_name: Ask_Price, validation_class:AsciiType}
];
i have tried all possible changes to code in order to make row keys as string type but getting an error or even without usersWriter.newRow not able to write into sstable
while ((line = reader.readLine()) != null)
{
if (entry.parse(line, lineNumber))
{
//usersWriter.newRow(uuid);
usersWriter.newRow(String.valueOf(lineNumber));
usersWriter.addColumn(bytes("symbol"), bytes(entry.symbol), timestamp);
usersWriter.addColumn(bytes("timestamp1"), bytes(entry.timestamp1), timestamp);
usersWriter.addColumn(bytes("Bid_Price"), bytes(entry.Bid_Price), timestamp);
usersWriter.addColumn(bytes("Ask_Price"), bytes(entry.Ask_Price), timestamp);
}
lineNumber++;
}
getting an error as expected it is only taking ByteBuffer
usersWriter.newRow(String.valueOf(lineNumber));
^
required: ByteBuffer
found: String
reason: actual argument String cannot be converted to ByteBuffer by method invocation conversion
Any help to make string as row keys in sstable for the above column family definition.thanks.
