--------------------------------------
[~samrat] can you share your schema?
> Filtering on Secondary Index throws out of memory error even with limit 1 and
> mentioning the partition key in the where clause.

> Key: CASSANDRA-13599
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13599
> Project: Cassandra
> Issue Type: Bug
> Components: Secondary Indexes
> Environment: Using Cassandra 3.10 on Windows 7
> Reporter: Samrat Gandotra
> Priority: Major
>
> We have used secondary index on a column with very low cardinality.
> So if we use partition key and any secondary index value ( value which has
> millions of corresponding rows in the table) in the where clause with limit 1
> even then it takes lot of time to respond and atlast out of memory error
> occurs.
> The correct scenario should be that if we are mentioning a very small limit
> like 1 then the results should be shown immediately when the secondary index
> and partition key is used in the where clause.
