> Ozone: DeleteKey-5: Implement SCM DeletedBlockLog
> -------------------------------------------------
>
> Key: HDFS-12283
> URL: https://issues.apache.org/jira/browse/HDFS-12283
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone, scm
> Reporter: Weiwei Yang

>
> The DeletedBlockLog is a persisted log in SCM to keep tracking container
> blocks which are under deletion. It maintains info about under-deletion
> container blocks that notified by KSM, and the state how it is processed. We
> can use RocksDB to implement the 1st version of the log, the schema looks like
> ||TxID||ContainerName||Block List||ProcessedCount||
> |0|c1|b1,b2,b3|0|
> |1|c2|b1|3|
> |2|c2|b2, b3|-1|
> Some explanations
> # TxID is an incremental long value transaction ID for ONE container and
> multiple blocks
> # Container name is the name of the container
> # Block list is a list of block IDs
> # ProcessedCount is the number of times SCM has sent this record to datanode,
> it represents the "state" of the transaction, it is in range of \[-1, 5\], -1
> means the transaction eventually failed after some retries, 5 is the max
> number times of retries.
> We need to define {{DeletedBlockLog}} as an interface and implement this with
> RocksDB {{MetadataStore}} as the first version.
