Package	Description
org.opensearch.index	Core classes responsible for handling all indexing operations in OpenSearch

Class	Description
CountedBitSet	A CountedBitSet wraps a FixedBitSet but automatically releases the internal bitset when all bits are set to reduce memory usage.
GlobalCheckpointSyncAction	Background global checkpoint sync action initiated when a shard goes inactive.
GlobalCheckpointSyncAction.Request	Request for checkpoint sync action
LocalCheckpointTracker	This class generates sequences numbers and keeps track of the so-called "local checkpoint" which is the highest number for which all previous sequence numbers have been processed (inclusive).
ReplicationTracker	This class is responsible for tracking the replication group with its progress and safety markers (local and global checkpoints).
ReplicationTracker.CheckpointState	The state of the lucene checkpoint
ReplicationTracker.PrimaryContext	Represents the sequence number component of the primary context.
RetentionLease	A "shard history retention lease" (or "retention lease" for short) is conceptually a marker containing a retaining sequence number such that all operations with sequence number at least that retaining sequence number will be retained during merge operations (which could otherwise merge away operations that have been soft deleted).
RetentionLeaseActions	This class holds all actions related to retention leases.
RetentionLeaseActions.Add	Add retention lease action
RetentionLeaseActions.Add.TransportAction	Internal transport action
RetentionLeaseActions.AddRequest	Add retention lease request

RetentionLeaseActions.Renew.TransportAction	Internal transport action for renew
RetentionLeaseActions.RenewRequest	Renew Request action
RetentionLeaseActions.Response	The response
RetentionLeaseAlreadyExistsException	Exception thrown if a retention lease already exists
RetentionLeaseBackgroundSyncAction	Replication action responsible for background syncing retention leases to replicas.
RetentionLeaseBackgroundSyncAction.Request	Request for retention lease bground sync action

RetentionLeaseNotFoundException	Exception thrown when a retention lease is not found
RetentionLeases	Represents a versioned collection of retention leases.
RetentionLeaseStats	Represents retention lease stats.
RetentionLeaseSyncAction	Write action responsible for syncing retention leases to replicas.
RetentionLeaseSyncAction.Request	Request for retention lease sync action
RetentionLeaseSyncAction.Response	Response for retention lease sync action
RetentionLeaseSyncer	Syncs retention leases
RetentionLeaseSyncer.BackgroundSyncAction	Represents an action that is invoked periodically to sync retention leases to replica shards after some retention lease has been renewed or expired.
RetentionLeaseSyncer.SyncAction	Represents an action that is invoked to sync retention leases to replica shards after a retention lease is added or removed on the primary.
