amazon dynamodb - AWS Error Code: ValidationException, AWS Error Message: Consistent reads are not supported on global secondary indexes -

-

i started using amazon dynamodb , have issue query.

i have table dev_testgame1_mail id primary hash key , following 3 global secondary indexes,

  1. fromplayerid (hash key)
  2. toplayerid (hash key) + isread (range key)
  3. toplayerid (hash key) + enddate(range key)

i have above code query,

**dynamodbmail hashkobject = new dynamodbmail();             hashkobject.settoplayerid(playerid); condition enddaterangekeycondition = new condition();             //enddaterangekeycondition.withcomparisonoperator(comparisonoperator.null).withattributevaluelist(new attributevalue().withb(utils.convertdatetobytebuffer(dateutil.getutcdatetime())));             enddaterangekeycondition.withcomparisonoperator(comparisonoperator.null);              dynamodbqueryexpression<dynamodbmail> queryexpression = new dynamodbqueryexpression<dynamodbmail>();             queryexpression.withhashkeyvalues(hashkobject).withrangekeycondition("enddate", enddaterangekeycondition);             queryexpression.withindexname("gsi_tp_enddt").withlimit(pagesize).withscanindexforward(false);             return dynamodbmapper.querypage(dynamodbmail.class, queryexpression, new dynamodbmapperconfig(tablenameoverride.withtablenameprefix(utils.getdynamodbtablenameprefix(gameid, env))));**

and following error,

com.amazonaws.amazonserviceexception: status code: 400, aws service: amazondynamodbv2, aws request id: guubv24k2o40t276r9nnn0ekb7vv4kqnso5aemvjf66q9asuaajg, aws error code: validationexception, aws error message: consistent reads not supported on global secondary indexes

your appreciated on issue.

thanks arun

set consistent read property of queryexpression false. put line:

queryexpression.withconsistentread(false);

or 

queryexpression.setconsistentread(false);

before call

return dynamodbmapper.querypage(dynamodbmail.class, queryexpression, new dynamodbmapperconfig(tablenameoverride.withtablenameprefix(utils.getdynamodbtablenameprefix(gameid, env))));

as aside, don't think null rangekeycondition doing you.
