Is it possible from the c# API to query data rather than returning a number of records?

#region Fetch result

HBaseOperation.FetchSize = 100;
HBaseResultSet result = HBaseOperation.ScanTable(tableName, con);

#endregion Fetch result


Like this from the samples in the big data managment studio
scan 'Customers',{ FILTER => "ValueFilter(=,'binaryprefix:Elizabeth Lincoln')"}

Hi Brett,

 

We have added support for filtering in scan table method in “Syncfusion.ThriftHBase.Base” API in latest preview build 2.10.0.10 . 

Sample location:  Installed_Drive:\Syncfusion\BigDataSDK\2.10.0.10\Samples\C# HBase Samples\WPF\Samples\Filter\CS


Code snippet:

var filters = new List<string>()

              {

"SingleColumnValueFilter('info','FULLNAME',=,'binaryprefix:Katherine')","PrefixFilter('1002')"

              };

HBaseResultSet result = HBaseOperation.ScanTable(tableName, filters, con);





Thanks,
Baskaran V
