Upgrading
|
||||
---------
|
||||
- CAS and new features in CQL such as DROP COLUMN assume that cell
|
||||
timestamps are microseconds-since-epoch. Do not use these
|
||||
features if you are using client-specified timestamps with some
|
||||
other source.
|
||||
- Upgrading is ONLY supported from Cassandra 1.2.9 or later. This
|
||||
goes for sstable compatibility as well as network. When
|
||||
upgrading from an earlier release, upgrade to 1.2.9 first and
|
||||
run upgradesstables before proceeding to 2.0.

|
||||
timestamps are microseconds-since-epoch. Do not use these

other source.
|
||||
- Replication and strategy options do not accept unknown options anymore.
|
||||
This was already the case for CQL3 in 1.2 but this is now the case for
|
||||
thrift too.
