Install Oracle Software in silent mode 11gR2. But to be sure that it is supported, do not hesitate to open a git issue of ask in the slack channel. If you think a PostgreSQL extension is necessary for your application, you can use this example to test it. So YugabyteDB still balanced the storage. But a cached sequence may be better as it keeps rows together from the same session, but distributes those from concurrent sessions.Īnyway, I've run the above for a while, with more rows inserted ( from generate_series(1,100000)) and checked that tablet auto-split occurs:Īs you see, one is still at Split Depth 1 because no Sequential UUID went into this range, and another has been split 7 times. However, if there are not too many concurrent sessions, and the load is distributed with other tables, then maybe this UUID can benefit from colocation in DocDB and filesystem caches. In addition to that, having concurrent sessions touching the same key range will create a hotspot on one tablet. If you want a UUID, then the one from pgcrypto (already installed in YugabyteDB) gen_random_uuid() is probably the right one. Thanks to the LSM-Tree storage, YugabyteDB doesn't have the problems that sequential_uuids tries to solve ( WAL write amplification, B-Tree fragmentation and clustering factor). ⚠️ You must think about the consequence in a Distributed SQL database before using a time-based UUID. #POSTGRESQL YUM REPO FULL#
The full PostgreSQL-compatibility of the extension is confirmed by the regression tests. The only difference is because the regression test has no ORDER BY and the order of rows from a hash partitioned table (the default) in a distributed database is different than from the single-node heap table:
