@@@ -13,56 -13,6 +13,56 @@@ restore snapshots created with the prev
'sstableloader' tool. You can upgrade the file format of your snapshots
using the provided 'sstableupgrade' tool.
+3.0
+===
+
+New features
+------------
+ - Materialized Views, which allow for server-side denormalization, is now
+ available. Materialized views provide an alternative to secondary indexes
+ for non-primary key queries, and perform much better for indexing high
+ cardinality columns.
+ See
http://www.datastax.com/dev/blog/new-in-cassandra-3-0-materialized-views
+
+
+Upgrading
+---------
+ - 3.0 requires Java 8u20 or later.
+ - The default JVM GC has been changed to G1GC.
+ - The default JVM flag -XX:+PerfDisableSharedMem will cause the following
tools JVM
+ to stop working: jps, jstack, jinfo, jmc, jcmd as well as 3rd party
tools like Jolokia.
+ If you wish to use these tools you can comment this flag out in
cassandra-env.{sh,ps1}
+ - New write stages have been added for batchlog and materialized view
mutations
+ you can set their size in cassandra.yaml
+ - User defined functions are now executed in a sandbox.
+ To use UDFs and UDAs, you have to enable them in cassandra.yaml.
+ - New SSTable version 'la' with improved bloom-filter false-positive
handling
+ compared to previous version 'ka' used in 2.2 and 2.1. Running
sstableupgrade
+ is not necessary but recommended.
+ - Before upgrading to 3.0, make sure that your cluster is in complete
agreement
+ (schema versions outputted by `nodetool describecluster` are all the
same).
+ - Schema metadata is now stored in the new `system_schema` keyspace, and
+ legacy `system.schema_*` tables are now gone; see CASSANDRA-6717 for
details.
+ - Pig's CassandraStorage has been removed. Use CqlNativeStorage instead.
+ - Hadoop BulkOutputFormat and BulkRecordWriter have been removed; use
+ CqlBulkOutputFormat and CqlBulkRecordWriter instead.
+ - Hadoop ColumnFamilyInputFormat and ColumnFamilyOutputFormat have been
removed;
+ use CqlInputFormat and CqlOutputFormat instead.
+ - Hadoop ColumnFamilyRecordReader and ColumnFamilyRecordWriter have been
removed;
+ use CqlRecordReader and CqlRecordWriter instead.
+ - hinted_handoff_enabled in cassandra.yaml no longer supports a list of
data centers.
+ To specify a list of excluded data centers when hinted_handoff_enabled
is set to true,
+ use hinted_handoff_disabled_datacenters, see CASSANDRA-9035 for details.
+ - The `sstable_compression` and `chunk_length_kb` compression options have
been deprecated.
+ The new options are `class` and `chunk_length_in_kb`. Disabling
compression should now
+ be done by setting the new option `enabled` to `false`.
+ - Only map syntax is now allowed for caching options.
ALL/NONE/KEYS_ONLY/ROWS_ONLY syntax
+ has been deprecated since 2.1.0 and is being removed in 3.0.0.
+ - Batchlog entries are now stored in a new table - system.batches.
+ The old one has been deprecated.
+ - JMX methods set/getCompactionStrategyClass have been removed, use
- set/getLocalCompactionStrategy or set/getLocalCompactionStrategyJson
instead.
++ set/getCompactionParameters or set/getCompactionParametersJson instead.
+

- Commit log files are no longer recycled by default, due to negative
performance implications. This can be enabled again with the
commitlog_segment_recycling option in your cassandra.yaml
+ - JMX methods set/getCompactionStrategyClass have been deprecated, use
+ set/getCompactionParameters/set/getCompactionParametersJson instead
