Output Data Fields

The following fields display for each replica.

Field Description
cluster The cluster on which the replica resides.
changelog Identifies the destination stream topic for the changelog.
changelogstream Identifies the destination stream for the changelog.
replicaState The replication state. For information about the replication states, see Table Replication States.
paused A Boolean values that specifies if replication is paused.
throttle A Boolean value that specifies if replication is throttled.
idx The internal index value.
networkencryption A Boolean value that specifies if replication is encrypted.
synchronous A Boolean value that specifies whether replication is synchronous or asynchronous.
networkcompression The type of on-wire compression.
propagateExistingData Identifies whether existing data in the source table is propagated to the destination stream topic.
isUptodate A Boolean value that specifies if the replica is up-to-date.
minPendingTS The epoch time in milliseconds of the oldest operation that has yet to be replicated to the replica.
maxPendingTS The epoch time in milliseconds of the newest operation that has yet to be replicated to the replica.
bytesPending The number of bytes that have yet to be replicated to the replica.
putsPending The number of puts that have yet to be replicated to the replica.
bucketsPending The number of buckets that have yet to be replicated to the replica.
uuid The table UUID.
copyTableCompletionPercentage When propagation of existing data is in progress, this value is the percentage of data from the source table that has been propagated to the destination stream topic.
Note: When replicating MapR Database data, the copyTablePercentageCompletion data may re-adjust to a lower rate. This depends on table region (also referred to as tablets) splits and merges as well as the rate of incoming data to replicating data.
errors If applicable, an error is displayed.
