Methods

Modifier and Type	Method and Description
int	getMaxReplicationThreads() The total number of threads available to replicate data to peers.
int	getNumConfiguredPeers() Peers are systems which data can be replicated to.
int	getNumFilesPendingReplication() A system may have multiple Replication targets, each of which have a queue of files to be replicated.

Method Detail

getNumFilesPendingReplication

int getNumFilesPendingReplication()

A system may have multiple Replication targets, each of which have a queue of files to be replicated. This returns the sum across all targets, not de-duplicating files.

Returns:

The number of files pending replication across all targets

getMaxReplicationThreads

int getMaxReplicationThreads()

The total number of threads available to replicate data to peers. Each TabletServer has a number of threads devoted to replication, so this value is affected by the number of currently active TabletServers.

Returns:

The number of threads available to replicate data across the instance

getNumConfiguredPeers

int getNumConfiguredPeers()

Peers are systems which data can be replicated to. This is the number of peers that are defined, but this is not necessarily the number of peers which are actively being replicated to.

Returns:

The number of peers/targets which are defined for data to be replicated to.
