You can upgrade the file format of your snapshots using the provided 'sstableupgrade' tool. +4.0 +=== + +New features +------------ + - The currentTimestamp, currentDate, currentTime and currentTimeUUID functions have been added. + See CASSANDRA-13132 + - Support for arithmetic operations between `timestamp`/`date` and `duration` has been added. + See CASSANDRA-11936 + - Support for arithmetic operations on number has been added. See CASSANDRA-11935 + - Preview expected streaming required for a repair (nodetool repair --preview), and validate the + consistency of repaired data between nodes (nodetool repair --validate). See CASSANDRA-13257 + - Support for selecting Map values and Set elements has been added for SELECT queries. See CASSANDRA-7396 + - Change-Data-Capture has been modified to make CommitLogSegments available + immediately upon creation via hard-linking the files. This means that incomplete + segments will be available in cdc_raw rather than fully flushed. See documentation + and CASSANDRA-12148 for more detail. + +Upgrading +--------- + - Support for legacy auth tables in the system_auth keyspace (users, + permissions, credentials) and the migration code has been removed. Migration + of these legacy auth tables must have been completed before the upgrade to + 4.0 and the legacy tables must have been removed. See the 'Upgrading' section + for version 2.2 for migration instructions. + - Cassandra 4.0 removed support for the deprecated Thrift interface. Amongst + Tother things, this imply the removal of all yaml option related to thrift + ('start_rpc', rpc_port, ...). + - Cassandra 4.0 removed support for any pre-3.0 format. This means you + cannot upgrade from a 2.x version to 4.0 directly, you have to upgrade to + a 3.0.x/3.x version first (and run upgradesstable). In particular, this + mean Cassandra 4.0 cannot load or read pre-3.0 sstables in any way: you + will need to upgrade those sstable in 3.0.x/3.x first. + - Upgrades from 3.0.x or 3.x are supported since 3.0.13 or 3.11.0, previous + versions will causes issues during rolling upgrades (CASSANDRA-13274). + - Cassandra will no longer allow invalid keyspace replication options, such + as invalid datacenter names for NetworkTopologyStrategy. Operators MUST + add new nodes to a datacenter before they can set set ALTER or CREATE + keyspace replication policies using that datacenter. Existing keyspaces + will continue to operate, but CREATE and ALTER will validate that all + datacenters specified exist in the cluster. + - Cassandra 4.0 fixes a problem with incremental repair which caused repaired + data to be inconsistent between nodes. The fix changes the behavior of both + full and incremental repairs. For full repairs, data is no longer marked + repaired. For incremental repairs, anticompaction is run at the beginning + of the repair, instead of at the end. If incremental repair was being used + prior to upgrading, a full repair should be run after upgrading to resolve + any inconsistencies. + - Config option index_interval has been removed (it was deprecated since 2.0) + - Deprecated repair JMX APIs are removed. + - The version of snappy-java has been upgraded to 1.1.2.6 + - the miniumum value for internode message timeouts is 10ms. Previously, any + positive value was allowed. See cassandra.yaml entries like + read_request_timeout_in_ms for more details. + + 3.11.1 + ====== - Materialized Views - ------------------- + Upgrading + --------- + - Creating Materialized View with filtering on non-primary-key base column + (added in CASSANDRA-10368) is disabled, because the liveness of view row + is depending on multiple filtered base non-key columns and base non-key + column used in view primary-key. This semantic cannot be supported without + storage format change, see CASSANDRA-13826. For append-only use case, you + may still use this feature with a startup flag: "-Dcassandra.mv.allow_filtering_nonkey_columns_unsafe=true" + + -Materialized Views (only when upgrading from 3.X or any version lower than 3.0.15) ++Materialized Views (only when upgrading from any version lower than 3.0.15 (3.0 series) or 3.11.1 (3.X series)) + --------------------------------------------------------------------------------------- - Cassandra will no longer allow dropping columns on tables with Materialized Views. - A change was made in the way the Materialized View timestamp is computed, which may cause an old deletion to a base column which is view primary key (PK) column --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
