  6. def backfillToVersion(logStore: LogStore, hadoopConf: Configuration, logPath: Path, managedCommitTableConf: Map[String, String], startVersion: Long = 0, endVersionOpt: Option[Long] = None): Unit

    API to ask the Commit-Owner to backfill all commits >= 'startVersion' and <= endVersion.

    API to ask the Commit-Owner to backfill all commits >= 'startVersion' and <= endVersion.

    If this API returns successfully, that means the backfill must have been completed, although the Commit-Owner may not be aware of it yet.

  7. val batchSize: Long

    Size of batch that should be backfilled.

    Size of batch that should be backfilled. So every commit version which satisfies commitVersion % batchSize == 0 will trigger a backfill.

    API to commit the given set of actions to the table represented by given logPath at the given commitVersion.

    returns

    CommitResponse which contains the file status of the commit file. If the commit is already backfilled, then the fileStatus could be omitted from response and the client could get the info by themselves.

  15. def getCommits(logPath: Path, managedCommitTableConf: Map[String, String], startVersion: Long, endVersion: Option[Long]): GetCommitsResponse

    API to get the un-backfilled commits for the table represented by the given logPath.

    API to get the un-backfilled commits for the table represented by the given logPath. Commits older than startVersion, or newer than endVersion (if given), are ignored. The returned commits are contiguous and in ascending version order. Note that the first version returned by this API may not be equal to the startVersion. This happens when few versions starting from startVersion are already backfilled and so commit-owner may have stopped tracking them. The returned latestTableVersion is the maximum commit version ratified by the Commit-Owner. Note that returning latestTableVersion as -1 is acceptable only if the commit-owner never ratified any version i.e. it never accepted any un-backfilled commit.

    returns

    GetCommitsResponse which has a list of Commits and the latestTableVersion which is tracked by CommitOwnerClient.

  38. def registerTable(logPath: Path, currentVersion: Long, currentMetadata: Metadata, currentProtocol: Protocol): Map[String, String]

    API to register the table represented by the given logPath with the given currentTableVersion.

    API to register the table represented by the given logPath with the given currentTableVersion. This API is called when the table is being converted from filesystem table to managed-commit table. - The currentTableVersion is the version of the table just before conversion. - The currentTableVersion + 1 represents the commit that will do the conversion. This must be backfilled atomically. - The currentTableVersion + 2 represents the first commit after conversion. This will go via the CommitOwnerClient and it could choose whether it wants to write unbackfilled commits and backfill them later. When a new managed-commit table is being created, the currentTableVersion will be -1 and the upgrade commit needs to be a file-system commit which will write the backfilled file directly.

    returns

    A map of key-value pairs which is issued by the commit-owner to identify the table. This should be stored in the table's metadata. This information needs to be passed in other table specific APIs like commit / getCommits / backfillToVersion to identify the table.

  39. def semanticEquals(other: CommitOwnerClient): Boolean

    Determines whether this CommitOwnerClient is semantically equal to another CommitOwnerClient.

    Determines whether this CommitOwnerClient is semantically equal to another CommitOwnerClient.

    Semantic equality is determined by each CommitOwnerClient implementation based on whether the two instances can be used interchangeably when invoking any of the CommitOwnerClient APIs, such as commit, getCommits, etc. For e.g., both the instances might be pointing to the same underlying endpoint.
