Utilities for HPE Ezmeral Data Fabric Streams

HPE Ezmeral Data Fabric Streams provides the utilities for operating on streams and topics.

NOTE
HPE Ezmeral Data Fabric Streams cannot use HPE Ezmeral Data Fabric Database Shell to perform operations on streams or topics.
mapr copystream
This utility copies data from one HPE Ezmeral Data Fabric Stream to another HPE Ezmeral Data Fabric Stream. You can use it, for example, if you want to set up replication manually from one stream to another.
mapr diffstreams
This utility compares the message IDs, metadata, and data in two HPE Ezmeral Data Fabric Streams. Then, generates two directories that contain sequence files that you can use to merge the rows from the two HPE Ezmeral Data Fabric Streams.
mapr diffstreamswithcrc
This utility uses a cyclic redundancy check to detect differences between sets of messages in the specified HPE Ezmeral Data Fabric Streams. Then, for each set of non-identical messages, it performs a detailed comparison. Finally, it generates one or more directories of sequence files.
mapr exportstream and mapr importstream
Use these utilities together to export data from HPE Ezmeral Data Fabric Streams into binary sequence files, and then import the data from the binary sequence files into other HPE Ezmeral Data Fabric Streams. You can also use the mapr importstream utility to import changes that are specified in sequence files output by the mapr diffstreams utility.
mapr perfconsumer
This utility runs a consumer reading messages from topics in a HPE Ezmeral Data Fabric Stream. Use this utility to run consumers when you want to estimate the performance of consumers for your HPE Ezmeral Data Fabric Streams applications, given your network configuration.
mapr perfproducer
This utility runs a producer, generating messages and publishing them to a HPE Ezmeral Data Fabric Stream. Use this utility to run producers when you want to estimate the performance of producers for your HPE Ezmeral Data Fabric Streams applications, given your network configuration.
mapr streamanalyzer
This light-weight utility, which is a sample application for the Streams Java class for analytics on HPE Ezmeral Data Fabric Streams, lets you count the messages in a stream or a subset of the topics in a stream. The utility also lets you print either whole retrieved messages or a subset of the fields in each message.
