To configure data compression and encryption in Flume, you can follow these steps:

Data Compression Configuration:
In the Flume configuration file, data compression can be achieved using GzipSource and GzipSink. For example, the following configuration can be added between the source and sink.

agent.sources = source1
agent.channels = channel1
agent.sinks = sink1

agent.sources.source1.type = avro
agent.sources.source1.channels = channel1
agent.sources.source1.bind = localhost
agent.sources.source1.port = 41414

agent.sinks.sink1.type = avro
agent.sinks.sink1.channel = channel1
agent.sinks.sink1.hostname = localhost
agent.sinks.sink1.port = 41415
agent.sinks.sink1.compressionCodec = gzip

Encrypting Data Configuration:
To implement data encryption in Flume, you can use SSL/TLS protocol to ensure that data is secure during transmission. In the Flume configuration file, you can add the following configuration to enable SSL/TLS encryption.

agent.sources = source1
agent.channels = channel1
agent.sinks = sink1

agent.sources.source1.type = avro
agent.sources.source1.channels = channel1
agent.sources.source1.bind = localhost
agent.sources.source1.port = 41414
agent.sources.source1.ssl = true
agent.sources.source1.keystore = /path/to/keystore
agent.sources.source1.keystorePassword = password

agent.sinks.sink1.type = avro
agent.sinks.sink1.channel = channel1
agent.sinks.sink1.hostname = localhost
agent.sinks.sink1.port = 41415
agent.sinks.sink1.ssl = true
agent.sinks.sink1.truststore = /path/to/truststore
agent.sinks.sink1.truststorePassword = password

In the configuration above, you need to provide the paths and passwords for the keystore and truststore to set up SSL/TLS encryption.

Please note that the above configuration is for reference only, the specific configuration will depend on your environment and requirements. It is recommended to appropriately configure Flume based on your specific situation to achieve data compression and encryption.
