| ## Optimization | ||
|
|
||
| ## Legacy versions | ||
| - Patterns can now be used in `WHERE` statements. For example: `MATCH (v:player) WHERE (v)-[:like]->() RETURN v`. [#3997](https://github.com/vesoft-inc/nebula/pull/3997) | ||
| - `CLEAR SPACE` can be used to clear graph space and index data, but the graph space schema and index names are reserved. [#3989](https://github.com/vesoft-inc/nebula/pull/3989) | ||
| - The vertex alias can be repeated in match patterns, like `MATCH (v)-->(v)`. [#3929](https://github.com/vesoft-inc/nebula/pull/3929) | ||
| - Optimized `SUBGRAPH` and `FIND PATH` for better performance. [#3871](https://github.com/vesoft-inc/nebula/pull/3871) [#4095](https://github.com/vesoft-inc/nebula/pull/4095) | ||
| - Optimized query paths to reduce redundant paths and time complexity.[4126](https://github.com/vesoft-inc/nebula/pull/4162) | ||
| - Optimized the method to get properties for better performance of `MATCH` statements. [#3750](https://github.com/vesoft-inc/nebula/pull/3750) | ||
| - Optimized `GO` and `YIELD` clauses to avoid extracting redundant properties. [#3974](https://github.com/vesoft-inc/nebula/pull/3974) | ||
| - Support for filter and limit pushdown when getting properties. [3844](https://github.com/vesoft-inc/nebula/pull/3844) [3839](https://github.com/vesoft-inc/nebula/pull/3839) | ||
| - Support for aggregation pushdown in `LOOKUP` statements. [#3504](https://github.com/vesoft-inc/nebula/pull/3504) | ||
| - `maxHop` is optional in MATCH variable-length paths.[#3881](https://github.com/vesoft-inc/nebula/pull/3881) | ||
| - Graph spaces are physically deleted after using `DROP SPACE`. [#3913](https://github.com/vesoft-inc/nebula/pull/3913) | ||
| - Optimized number parsing in date time, date, time. [#3797](https://github.com/vesoft-inc/nebula/pull/3797) | ||
| - Added the `toSet` function which converts `LIST` or `SET` to `SET`. [#3594](https://github.com/vesoft-inc/nebula/pull/3594) | ||
| - nGQL statements can be used to display the HTTP port of Nebula Graph services and the HTTP2 port has been disabled. [#3808](https://github.com/vesoft-inc/nebula/pull/3808) | ||
| - The number of sessions for connections to each graphd with the same client IP and the same user is limited. [#3729](https://github.com/vesoft-inc/nebula/pull/3729) | ||
| - Optimized the waiting mechanism to ensure a timely connection to the metad after the storaged starts. [#3971](https://github.com/vesoft-inc/nebula/pull/3971) | ||
| - When a node has multiple paths and an error of the disk corresponding to a particular path occurs, it is no longer to rebuild the node. [#4131](https://github.com/vesoft-inc/nebula/pull/4131) | ||
| - Optimized the job manager. [#3976](https://github.com/vesoft-inc/nebula/pull/3976) [#4045](https://github.com/vesoft-inc/nebula/pull/4045) [#4001](https://github.com/vesoft-inc/nebula/pull/4001) | ||
| - The `DOWNLOAD` and `INGEST` SST files are now managed with the job manager. [#3994](https://github.com/vesoft-inc/nebula/pull/3994) | ||
| - Support for error code display when a job fails. [#4067](https://github.com/vesoft-inc/nebula/pull/4067) | ||
| - The OS page cache can be disabled and the block cache and Nebula Graph storage cache can only be used in a shared environment, to avoid memory usage interference between applications. [#3890](https://github.com/vesoft-inc/nebula/pull/3890) | ||
| - Updated the default value of the KV separation threshold from 0 to 100. [#3879](https://github.com/vesoft-inc/nebula/pull/3879) | ||
| - Support for using gflag to set the upper limit of expression depth for a better fit of different machine environments. [#3722](https://github.com/vesoft-inc/nebula/pull/3722) | ||
| - Added a permission check for `KILL QUERY`. When the authorization is enabled, the GOD user can kill any query and the users with other roles can only kill queries that they own. [#3896](https://github.com/vesoft-inc/nebula/pull/3896) | ||
| - Support for more complier launchers, including distcc and sccache. [#3896](https://github.com/vesoft-inc/nebula/pull/3896) | ||
| - More dumping tables are supported with the meta dump tool. [#3870](https://github.com/vesoft-inc/nebula/pull/3870) | ||
