+# Pegasus Change Log
+
+## 2.5.0
+
+### Behavior changes
+* Use official releases of RocksDB for Pegasus, instead of the modified
versions based on a fork of it due to some historical reasons. Since Pegasus
2.1.0, actually most of the modifications have been removed, while few of them
were left to keep backward compatible. Pegasus 2.5.0 would turn to official
release, thus it should be noted that to use 2.5.0, the server must be upgraded
from 2.1, 2.2, 2.3 or 2.4, to ensure that in MANIFEST files there are no
introduced tags by the modified ver [...]
+* Now the logs in servers and C++ clients are in increase severity order of
`DEBUG`, `INFO`, `WARNING`, `ERROR` and `FATAL`, which means the inverse order
between `DEBUG` and `INFO` has been corrected.
[#1200](https://github.com/apache/incubator-pegasus/pull/1200)
+* All shared log files would be flushed and removed for garbage collection,
while before 2.5.0 there is at least 1 shared log file which is never removed,
though long before that the private logs were written as WAL instead of shared
logs. [#1594](https://github.com/apache/incubator-pegasus/pull/1594)
+* No longer support EOL OS versions, including Ubuntu 16.04 and CentOS 6.
[#1553](https://github.com/apache/incubator-pegasus/pull/1553),
[#1557](https://github.com/apache/incubator-pegasus/pull/1557)
+
+### New Features
+* Add a new ACL based on Apache Ranger to provide fine-grained access control
to global-level, database-level and table-level resources. On the other hand,
it is also compatible with the old coarse-grained ACL.
[#1054](https://github.com/apache/incubator-pegasus/issues/1054)
+* Add support to query and update table-level RocksDB options at runtime,
where currently only `num_levels` and `write_buffer_size` are supported; other
options would be added gradually, if necessary.
[#1511](https://github.com/apache/incubator-pegasus/pull/1511)
+* Add a new `rename` command for cpp-shell, allowing users to rename a table.
[#1272](https://github.com/apache/incubator-pegasus/pull/1272)
+* Add a configuration `[network] enable_udp` to control if UDP service is
started. The service would not be started when set to false.
[#1132](https://github.com/apache/incubator-pegasus/pull/1132)
+* Add support to dump the statistical information while using `jemalloc`.
[#1133](https://github.com/apache/incubator-pegasus/pull/1133)
+* Support `success_if_exist` option for the interface of creating table to
cpp-shell, java and go clients.
[#1148](https://github.com/apache/incubator-pegasus/pull/1148)
+* Add a new interface `listApps` to the Java client to list all tables.
[#1471](https://github.com/apache/incubator-pegasus/pull/1471)
+* Add a new option `[replication] crash_on_slog_error` to make it possible to
exit the replica server if the shared log failed to be replayed, instead of
trashing all the replicas on the server.
[#1574](https://github.com/apache/incubator-pegasus/pull/1574)
+* Pegasus could be built on more platforms: Ubuntu 22.04/Clang 14, M1 MacOS.
[#1350](https://github.com/apache/incubator-pegasus/pull/1350),
[#1094](https://github.com/apache/incubator-pegasus/pull/1094)
+* Pegasus could be developed and built in a docker environment via
VSCode(https://code.visualstudio.com/docs/devcontainers/containers), which is
more friendly to newbies.
[#1544](https://github.com/apache/incubator-pegasus/pull/1544)
+
+### Performance Improvements
+* Improve the performance of `count_data` of cpp-shell by only transferring
the number of records rather than the real data.
[#1091](https://github.com/apache/incubator-pegasus/pull/1091)
+
+### Bug fixes
+* Fix a bug that the RocksDB library is not built in **Release** version,
which may cause terrible performance issues.
[#1340](https://github.com/apache/incubator-pegasus/pull/1340)
+* Fix a bug in the Go client that the `startScanPartition()` operation could
not be performed correctly if some partitions was migrated.
[#1106](https://github.com/apache/incubator-pegasus/pull/1106)
+* Fix a bug that some RockDB options could not be loaded correctly if updating
the config file and restarting the replica server.
[#1108](https://github.com/apache/incubator-pegasus/pull/1108)
+* Create a `stat` table to avoid errors reported from cpp-collector.
[#1155](https://github.com/apache/incubator-pegasus/pull/1155)
+* Fix bugs where wrong error code is passed to callback and directory is not
rolled back correctly for failure while resetting the mutation log with log
files of another directory.
[#1208](https://github.com/apache/incubator-pegasus/pull/1208)
+* Fix a bug in admin-cli that reports an incorrect error `doesn't have enough
space` when executing the `partition-split start` command.
[#1289](https://github.com/apache/incubator-pegasus/pull/1289)
+* Fix a bug in Java client that the `batchGetByPartitions()` API may throw
`IndexOutOfBoundsException` exception if partial partitions get response
failed. [#1411](https://github.com/apache/incubator-pegasus/pull/1411)
+* Trash the corrupted replica to the path
`<app_id>.<pid>.pegasus.<timestamp>.err` when the RocksDB instance reports
corruption error while executing write operations instead of leaving it in the
same place, to avoid endless corruption errors. Also trash the corrupted
replica to that path when corruption errors occur while executing read
operations (instead of doing nothing). The trashed replica can be recovered
automatically in a cluster deployment, or must be repaired manually in singl
[...]
+* Fix a bug of replica server crash if `.init-info` file is missing.
[#1428](https://github.com/apache/incubator-pegasus/pull/1428)
+* Fix a bug of the Go client may hang if some replica servers are down.
[#1444](https://github.com/apache/incubator-pegasus/pull/1444)
+* Fix a bug that the replica server would crash when opening a replica with a
corrupted RocksDB instance, whose directory will be marked as trash then.
[#1450](https://github.com/apache/incubator-pegasus/issues/1450)
+* Fix a bug that there is no interval between two attempts once
`ERR_BUSY_CREATING` or `ERR_BUSY_DROPPING` error is received while creating or
dropping a table by cpp-shell.
[#1453](https://github.com/apache/incubator-pegasus/pull/1453)
+* Fix a bug of the replica server crash in the Ingestion procedure of Bulk
Load data. [#1563](https://github.com/apache/incubator-pegasus/pull/1563)
+* Mark the data directory as failed and stop assigning new replicas to it once
IO errors are found for it.
