Enclosing class:

AcidUtils

public static class AcidUtils.ParsedBaseLight
extends Object

Since version 3 but prior to version 4, format of a base is "base_X" where X is a writeId. If this base was produced by a compactor, X is the highest writeId that the compactor included. If this base is produced by Insert Overwrite stmt, X is a writeId of the transaction that executed the insert. Since Hive Version 4.0, the format of a base produced by a compactor is base_X_vY. X is like before, i.e. the highest writeId compactor included and Y is the visibilityTxnId of the transaction in which the compactor ran. (v(isibility) is a literal to help parsing).
