-------------------------------------------
Summary: COPY TO Column of Type Double Precision gets Truncated to
lesser precision
Key: CASSANDRA-11233
URL: https://issues.apache.org/jira/browse/CASSANDRA-11233
Project: Cassandra
Issue Type: Bug
Components: CQL
Environment: [cqlsh 5.0.1 | Cassandra 2.1.11.908 | DSE 4.8.2 | CQL
spec 3.2.1 | Native protocol v3]
Reporter: Jason Walkowicz
I am copying a table between two exact table configs but different names with
the CQLSH COPY command.
Example:
COPY "my"."data"(number) TO 'export.csv';
COPY "my"."datacopy"(number) FROM 'export.csv';
The column i'm copying TO and FROM is of type double. The problem is it appears
that the copy is truncating the precision of the column.
For example:
Original Data:
5.084936038014788E8
After Copy
5.0849E8
