Subject [jira] [Commented] (HBASE-6785) Convert AggregateProtocol to protobuf defined coprocessor service
Date Wed, 03 Oct 2012 02:10:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468260#comment-13468260
] 

Ted Yu commented on HBASE-6785:
-------------------------------

Thanks Devaraj for being considerate.
w.r.t. the placeholder 'bytes' for the ColumnInterpreter serialization, let's consider the
following interpreter from HBASE-6669:
{code}
+public class BigDecimalColumnInterpreter implements
+    ColumnInterpreter<BigDecimal, BigDecimal> {
+
+  private BigDecimal minValue;
+  private BigDecimal maxValue;
{code}
Looks like the user may need to serialize more than one field.
How about changing the field to this:
{code}
    optional repeated bytes interpreterSpecificBytes = 2;
{code}

> With coprocessor endpoints now exposed as protobuf defined services, we should convert
over all of our built-in endpoints to PB services.
