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 HPE Ezmeral Data Fabric 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. |
