Upgrade from Cassandra 2.0 and + older versions is not supported. + - The 'memtable_allocation_type: offheap_objects' option has been removed. It should + be re-introduced in a future release and you can follow CASSANDRA-9472 to know more. - - The LIMIT clause applies now only to the number of rows returned to the user, - not to the number of row queried. By consequence, queries using aggregates will not - be impacted by the LIMIT clause anymore. + - The native protocol versions 1 and 2 are not supported anymore. + - 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`. + - The compression option `crc_check_chance` became a top-level table option, but is currently + enforced only against tables with enabled compression. + - 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. New syntax has been added to create + and query row-based indexes, which are not explicitly linked to a single column in the + base table. + 2.2.2 ===== http://git-wip-us.apache.org/repos/asf/cassandra/blob/fce444f6/test/unit/org/apache/cassandra/cql3/validation/operations/AggregationTest.java ----------------------------------------------------------------------
