You can upgrade the file format of your snapshots using the provided 'sstableupgrade' tool. +2.1 +=== + +New features +------------ + - SSTable data directory name is slightly changed. Each directory will + have hex string appended after CF name, e.g. + ks/cf-5be396077b811e3a3ab9dc4b9ac088d/ + This hex string part represents unique ColumnFamily ID. + Note that existing directories are used as is, so only newly created + directories after upgrade have new directory name format. + - Saved key cache files also have ColumnFamily ID in their file name. + - It is now possible to do incremental repairs, sstables that have been + repaired are marked with a timestamp and not included in the next + repair session. Use nodetool repair -par -inc to use this feature. + A tool to manually mark/unmark sstables as repaired is available in + tools/bin/sstablerepairedset. + +Upgrading +--------- + - Rolling upgrades from anything pre-2.0.6 is not supported. + - For leveled compaction users, 2.0 must be atleast started before + upgrading to 2.1 due to the fact that the old JSON leveled + manifest is migrated into the sstable metadata files on startup + in 2.0 and this code is gone from 2.1. + - For size-tiered compaction users, Cassandra now defaults to ignoring + the coldest 5% of sstables. This can be customized with the + cold_reads_to_omit compaction option; 0.0 omits nothing (the old + behavior) and 1.0 omits everything. + - Multithreaded compaction has been removed. + - Counters implementation has been changed, replaced by a safer one with + less caveats, but different performance characteristics. You might have + to change your data model to accomodate the new implementation. + (See https://issues.apache.org/jira/browse/CASSANDRA-6504 and the dev + blog post at http://www.datastax.com/dev/blog/<PLACEHOLDER> for details). + - (per-table) index_interval parameter has been replaced with + min_index_interval and max_index_interval paratemeters. index_interval + has been deprecated. + + 2.0.6 + ===== + + New features + ------------ + - CQL now support static columns, allows to batch multiple conditional updates + and has a new syntax for slicing over multiple clustering columns + (http://goo.gl/B6qz4j). + - Repair can be restricted to a set of nodes using the -hosts option in nodetool. + - A new 'nodetool taketoken' command relocate tokens with vnodes. + - Hinted handoff can be enabled only for some data-centers (see + hinted_handoff_enabled in cassandra.yaml) + + Upgrading + --------- + - Nothing specific to this release, but please see 2.0.6 if you are upgrading + from a previous version. + + 2.0.5 ===== http://git-wip-us.apache.org/repos/asf/cassandra/blob/5310f26d/debian/changelog ---------------------------------------------------------------------- diff --cc debian/changelog index a13370f,6cc4391..11f25cb --- a/debian/changelog +++ b/debian/changelog @@@ -1,9 -1,9 +1,15 @@@ +cassandra (2.1.0~beta1) unstable; urgency=low + + * New beta release + + -- Sylvain Lebresne <slebre...@apache.org> Mon, 17 Feb 2014 16:50:33 +0100 + + cassandra (2.0.6) unstable; urgency=low + + * New release + + -- Sylvain Lebresne <slebre...@apache.org> Fri, 07 Mar 2014 13:18:42 +0100 + cassandra (2.0.5) unstable; urgency=low * New release http://git-wip-us.apache.org/repos/asf/cassandra/blob/5310f26d/src/java/org/apache/cassandra/tools/NodeProbe.java ----------------------------------------------------------------------
