Migration
GetTwitter uses Version 1 of the Twitter REST API and relies on the retired Twitter Hosebird Client library.
GetTwitter supports several different endpoints for streaming Tweets, including Sample realtime Tweets and Filter realtime Tweets.
GetTwitter also supports configurable properties for filtering Tweets, but this filtering approach is not support in Version 2 of the Twitter REST API, and is not supported in ConsumeTwitter.
ConsumeTwitter uses Version 2 of the Twitter REST API. Twitter documentation provides a general guide for migrating from Version 1 to Version 2 for filtered streams and sampled streams.
ConsumeTwitter with Twitter API Version 2 requires a single OAuth 2.0 Bearer Token for app-only authentication. This approach replaces the API Key and Access Token approach required for GetTwitter.
Configuring ConsumeTwitter with the Sample Stream setting provides similar behavior to GetTwitter Sample Endpoint setting.
Configuring ConsumeTwitter with the Search Stream setting requires creating Filter Rules using the Twitter REST API outside of processor properties.
Flow Definitions
The Deprecated Flow Definition includes GetTwitter configured with the Sample Endpoint and without filters.
The Migrated Flow Definition includes ConsumeTwitter configured with the Sample Stream.

HashAttribute supports generating an MD5 digest of one more FlowFile attribute name and value pairs. The MD5 algorithm is not secure for cryptographic operations, and alternatives such as the SHA-2 or SHA-3 algorithms should be used.

Flow Definitions
The Deprecated Flow Definition includes HashContent configured to write a FlowFile attribute named hash.value using the SHA-256 algorithm.
