Upgrading
---------
- - Nothing specific to this release, but please see 2.2 if you are upgrading
- from a previous version.
+ - Max mutation size is now configurable via max_mutation_size_in_kb setting in
+ cassandra.yaml; the default is half the size commitlog_segment_size_in_mb * 1024.
+ - 3.0 requires Java 8u40 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 transaction log files have been introduced to replace the compactions_in_progress
+ system table, temporary file markers (tmp and tmplink) and sstable ancerstors.
+ Therefore, compaction metadata no longer contains ancestors. Transaction log files
+ list sstable descriptors involved in compactions and other operations such as flushing
+ and streaming. Use the sstableutil tool to list any sstable files currently involved
+ in operations not yet completed, which previously would have been marked as temporary.
+ A transaction log file contains one sstable per line, with the prefix "add:" or "remove:".
+ They also contain a special line "commit", only inserted at the end when the transaction
+ is committed. On startup we use these files to cleanup any partial transactions that were
+ in progress when the process exited. If the commit line is found, we keep new sstables
+ (those with the "add" prefix) and delete the old sstables (those with the "remove" prefix),
+ vice-versa if the commit line is missing. Should you lose or delete these log files,
+ both old and new sstable files will be kept as live files, which will result in duplicated
+ sstables. These files are protected by incremental checksums so you should not manually
+ edit them. When restoring a full backup or moving sstable files, you should clean-up
+ any left over transactions and their temporary files first. You can use this command:
+ ===> sstableutil -c ks table
+ See CASSANDRA-7066 for full details.
+ - 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.
+ - The 'index_interval' option for 'CREATE TABLE' statements, which has been deprecated
+ since 2.1 and replaced with the 'min_index_interval' and 'max_index_interval' options,
+ has now been removed.
+ - 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/getCompactionParameters or set/getCompactionParametersJson instead.
+ - SizeTieredCompactionStrategy parameter cold_reads_to_omit has been removed.
+ - The secondary index API has been comprehensively reworked. This will be a breaking
+ change for any custom index implementations, which should now look to implement
+ the new org.apache.cassandra.index.Index interface.
