GreptimeDB compatibility test
The compatibility test check whether a newer version of GreptimeDB can read from the data written by an old version of GreptimeDB (the "backward" compatibility), and vice-versa (the "forward" compatibility). It's often ran in the Github Actions to ensure there are no breaking changes by accident.
The test work like this: reuse the sqlness-runner two times but each for a read or write side. For example, if we are testing backward compatibility, we use sqlness-runner to run the SQLs with writes against the old GreptimeDB binary, and use the same sqlness-runner to run the SQLs with reads against the new GreptimeDB binary. If the reads were executed expectedly, we have achieved backward compatibility.
This compatibility test is inspired by Databend.
Usage
tests/compat/test-compat.sh <old_ver>
E.g. tests/compat/test-compat.sh 0.6.0 tests if the data written by GreptimeDB v0.6.0 can be read by current
version of GreptimeDB, and vice-versa. By "current", it's meant the fresh binary built by current codes.
Prerequisites
Current version of GreptimeDB's binaries must reside in ./bins:
./bins/current/greptime./bins/current/sqlness-runner
The steps in Github Action already assure that. When running in local host, you have to cp them from target directory
manually.
