Hi all, I'm using custom filters to retrieve filtered data from HBase using the native api. I noticed that the class full names of those custom filters is being sent as the bytes representation of the string using Text.writeString(). This consumes a lot of network bandwidth in my case due to using 5 custom filters per Get and issuing 1.5 million gets per minute. I took at look at the code (org.apache.hadoop.hbase.io.HbaseObjectWritable) and It seems that HBase registers its known classes (Get, Put, etc...) and associates them with an Integer (CODE_TO_CLASS and CLASS_TO_CODE). That integer is sent instead of the full class name for those known classes. I did a test reducing my custom filter class names to 2 or 3 letters and it improved my performance in 25%. Is there any way to "register" my custom filter classes to behave the same as HBase's classes? If not, does it make sense to introduce a change to do that? Is there any other workaround for this issue?
Thanks!
