Subject [jira] [Commented] (CASSANDRA-2500) Ruby dbi client (for CQL) that conforms to AR:ConnectionAdapter
Date Tue, 06 Sep 2011 17:53:10 GMT


Jonathan Ellis commented on CASSANDRA-2500:

Some tests that I'd like to see:

- a query against rows whose values are determined by default_validation_class
- a query demonstrating sparse columns across rows in a single resultset (e.g. row 1 has columns
A, B, row 2 has columns A, C)
- queries using UUID and long column names (these tend to be tricky)
- a test of Counter support
- a test showing all the CQL 1.1 data types in resultset values (Ascii, Boolean, Bytes, Date,
Double, Float, Long, UUID, UTF8)

Also, something is weird in
because mixing counters and noncounter data in a single CF is illegal (see CASSANDRA-2614):

  - !ruby/object:CassandraCQL::Thrift::ColumnDef
    name: votes
    validation_class: org.apache.cassandra.db.marshal.CounterColumnType
