Seastar's default limit of 10,000 iocbs per shard is too low for some workload (it places an upper bound on the number of idle connections, above which a crash occurs). Use the new Seastar feature to raise the default to 50000. Also multiply the global reservation by 5, and round it upwards so the number is less weird. This prevents io_setup() from failing. For tests, the reservation is reduced since they don't create large numbers of connections. This reduces surprise test failures when they are run on machines that haven't been adjusted. Fixes #9051 Closes #9052
Tests for Scylla with Redis API that should also pass, identically, against Redis.
Tests use the redis library for Redis API, and the pytest frameworks (both are available from Linux distributions, or with "pip install").
To run all tests against the local installation of Scylla with Redis API on
localhost:6379, just run pytest.
Some additional pytest options:
- To run all tests in a single file, do
pytest test_strings.py. - To run a single specific test, do
pytest test_strings.py::set. - Additional useful pytest options, especially useful for debugging tests:
- -v: show the names of each individual test running instead of just dots.
- -s: show the full output of running tests (by default, pytest captures the test's output and only displays it if a test fails)
