If you could provide any other necessary info regarding this enhancement would be great @Jiaweihu08 @cugni
from qbeast-spark.
More details about the implementation in #319
The idea is to have an interface such as:
/**
* A hook that can be run before a commit
*/
trait QbeastPreCommitHook {
/**
* The name of the hook
*/
val name: String
type PreCommitHookResponse = Map[String, String]
/**
* Run the hook with the given actions
*
* @param actions
* the actions to run the hook with
*/
def run(actions: Seq[Action]): PreCommitHookResponse
}
Users can extend that interface and add their code to run pre-commit checks or actions. Those actions need to return a Map[String, String]
of information they want to write on the Commit Log about the execution of the hook.
Registering a PreCommitHook
In terms of usage from the DataFrame API, one user may call the hook as:
df.write
.format("qbeast")
.option("qbeast.preCommitHook.my_hook_1", "my.hook.class.path")
.option("qbeast.preCommitHook.my_hook_1.arg1", "first_argument")
.save(...)
In that way, we will identify each hook by its name on the options.
Output of a PreCommitHook
Each implementation of a PreCommitHook
must return a Map[String, String]
with any useful information to register in the Commit Log. Qbeast will add the prefix registered in the options to the result map keys, and it will save it on the tags
variable in the CommitInfo
.
"commitInfo" {
"tags" {
"qbeast.preCommitHook.my_hook_1.write_id":"id",
"qbeast.preCommitHook.my_hook_1.cpu_time":"30ms"
}
}
