## MySQL
|
|
|
|
MySQL supports all the features that are mentioned in the [Migration](migrate.md) section,
|
|
and it's being tested constantly on the following 3 versions: `5.6.35`, `5.7.26` and `8`.
|
|
|
|
## MariaDB
|
|
|
|
MariaDB supports all the features that are mentioned in the [Migration](migrate.md) section,
|
|
and it's being tested constantly on the following 3 versions: `10.2`, `10.3` and latest version.
|
|
|
|
## PostgreSQL
|
|
|
|
PostgreSQL supports all the features that are mentioned in the [Migration](migrate.md) section,
|
|
and it's being tested constantly on the following 5 versions: `10`, `11`, `12`, `13` and `14`.
|
|
|
|
## CockroachDB **(<ins>preview</ins>)**
|
|
|
|
CockroachDB support is in preview and requires the [Atlas migration engine](#atlas-integration).
|
|
The integration with CRDB is currently tested on versions `v21.2.11`.
|
|
|
|
## SQLite
|
|
|
|
SQLite supports all _"append-only"_ features mentioned in the [Migration](migrate.md) section.
|
|
However, dropping or modifying resources, like [drop-index](migrate.md#drop-resources) are not
|
|
supported by default by SQLite, and will be added in the future using a [temporary table](https://www.sqlite.org/lang_altertable.html#otheralter).
|
|
|
|
## Gremlin
|
|
|
|
Gremlin does not support migration nor indexes, and **<ins>it's considered experimental</ins>**.
|
|
|
|
## TiDB **(<ins>preview</ins>)**
|
|
|
|
TiDB support is in preview and requires the [Atlas migration engine](#atlas-integration).
|
|
TiDB is MySQL compatible and thus any feature that works on MySQL _should_ work on TiDB as well.
|
|
For a list of known compatibility issues, visit: https://docs.pingcap.com/tidb/stable/mysql-compatibility
|
|
The integration with TiDB is currently tested on versions `5.4.0`, `6.0.0`.
