India's RJio Plots Open Source Disruption
Owned by Indian billionaire Mukesh Ambani, the telco believes that it is high time India developed products and services tailored specifically to the Indian market. "If you observe, a lot of effort has been put into the IT space [in India], but what has not happened is a focused effort [for innovation] in the telecom space," says Matthew Oommen, RJio's president of networks, global strategy and service development, on the sidelines of India's recent Digital Open Summit.

DO or UNDO - there is no VACUUM
To put this another way, it is in general true that PostgreSQL’s VACUUM implementation has gotten progressively better at reclaiming space occupied by dead tuples more quickly and with less expenditure of effort. And that’s really good, because the faster you reclaim space, the less new space you end up allocating, which keeps tables small and performance high. However, the examples above show that VACUUM isn’t the whole problem. In these examples, even if VACUUM ran at the earliest instant when it could reclaim the space occupied by dead tuples and ran infinitely fast, the table would still become bloated. In the case where the bloat is caused by many short queries run while one long-running transaction remains open, we could, with smarter snapshot management, limit the worst-case bloat to approximately a factor of two -- that is, we’d keep the version of the tuple visible to the old snapshot and the current version, and discard the intermediate versions, a trick PostgreSQL currently can’t manage. However, even a factor of two is a lot, and what if there are multiple distinct open snapshots? Further, in the case where the bloat is created by a SQL statement that induces scattered updates throughout the table, no improvement to VACUUM can possibly help. By the time that SQL statement finishes, the damage is already done.
