[cassandra] 24/44: [CEP-21] Bulk update of unit and dtests
This is an automated email from the ASF dual-hosted git repository.
samt pushed a commit to branch cep-21-tcm
in repository https://gitbox.apache.org/repos/asf/cassandra.git
commit 0e323c96fb290946764cd21a0057b4942777c3d2
Author: Sam Tunnicliffe <sa...@apache.org>
AuthorDate: Mon Mar 6 10:57:04 2023 +0000
[CEP-21] Bulk update of unit and dtests
Updates the existing unit and and dtests to work with TCM. In the vast
majority of cases, this just means changes to initialization or to
slightly updated method signatures.
In CEP-21 generally, the intention has been not to modify existing
public interfaces at all and to limit any changes to code on the
boundaries of internal subsystems. In addition, care has been taken to
only make minimal modifications to existing tests, and to preserve their
invariants. So although this commit is fairly large in terms of
number of files, it's changes should be semantically quite light.

+ * It is expected to end up with both nodes having only the definition of TABLE_ONE.
