| |
| 0.4.0 beta |
| * On-disk data format has changed to allow billions of keys/rows per |
| node instead of only millions |
| * Multi-keyspace support |
| * Scan all sstables for all queries to avoid situations where |
| different types of operation on the same ColumnFamily could |
| disagree on what data was present |
| * Snapshot support via JMX |
| * Thrift API has changed a _lot_: |
| - removed time-sorted CFs; instead, user-defined comparators |
| may be defined on the column names, which are now byte arrays. |
| Default comparators are provided for UTF8, Bytes, Ascii, Long (i64), |
| and UUID types. |
| - removed colon-delimited strings in thrift api in favor of explicit |
| structs such as ColumnPath, ColumnParent, etc. Also normalized |
| thrift struct and argument naming. |
| - Added columnFamily argument to get_key_range. |
| - Change signature of get_slice to accept starting and ending |
| columns as well as an offset. (This allows use of indexes.) |
| Added "ascending" flag to allow reasonably-efficient reverse |
| scans as well. Removed get_slice_by_range as redundant. |
| - get_key_range operates on one CF at a time |
| - changed `block` boolean on insert methods to ConsistencyLevel enum, |
| with options of NONE, ONE, QUORUM, and ALL. |
| - added similar consistency_level parameter to read methods |
| - column-name-set slice with no names given now returns zero columns |
| instead of all of them. ("all" can run your server out of memory. |
| use a range-based slice with a high max column count instead.) |
| * Removed the web interface. Node information can now be obtained by |
| using the newly introduced nodeprobe utility. |
| * More JMX stats |
| * Remove magic values from internals (e.g. special key to indicate |
| when to flush memtables) |
| * Rename configuration "table" to "keyspace" |
| * Moved to crash-only design; no more shutdown (just kill the process) |
| * Lots of bug fixes |

| * Workarounds for a weird bug in JDK select/register that seems |
| particularly common on VM environments. Cassandra should deploy |
| fine on EC2 now |
| * Much improved infrastructure: the beginnings of a decent test suite |
| ("ant test" for unit tests; "nosetests" for system tests), code |
| coverage reporting, etc. |
| * Expanded node status reporting via JMX |
| * Improved error reporting/logging on both server and client |
| * Reduced memory footprint in default configuration |
| * Combined blocking and non-blocking versions of insert APIs |
