This assumes your stream has the full event history … or that history/state is irrelevant, correct? If not, did you leave out a ‘copy history from source to target’ step?

An explicit shard id can ensure all related data across all tables can be on the same shard. Helpful for SQL JOIN operations. Picking the N least significant bits only a single table has good distribution and sort qualities, no cross-table

I think that’s the virtue of setting a high price on what you don’t want to do as your “not saying no”/funding strategy. It’s a reflection of your perceived opportunity cost. But you are right to suggest time-bounding your engagement u

Thanks, that was a good piece. It makes me want to share a story about an additional piece of perspective on what happened with Japan. I worked for a CEO in the early 90s who was midwestern ex-WallStreet-analyst deeply concerned about Ameri

I suspect there's no way ESR even got $1 million out of VA Linux. 1) ESR was on the Board of Directors of VA Linux and subject to the 180-day lockup so there is NO WAY he could sell under SEC regs until after 180 days so he couldn&#x27

Re ‘UPSERT is really for OLTP’, I find that claim surprising. If you mean the oracle UPSERT command, you may be right and should ignore my post, but if you mean upsert concept/terminology/MERGE-usage, I’m not sure I agree. I admit

You are bringing data from a transactional (OLTP) system into a reporting/analytics (OLAP, lakehouse, data warehouse, data hub) system. The analytic database is expected to maintain a list of all customers and their transactions going

The problem with plain/primitive upset/merge operations is they don’t always support handling of what should happen when a row is deleted from the source. People new to data engineering don’t always recognize this. Im those cases,

It’s worth reading Ray Ozzie’s (Lotus Notes creator)’s comment on this from a HN 2013 discussion: https://news.ycombinator.com/item?id=5846189 Before the software was released, Ray Ozzie and Kauffman openly described what t

Candidly this is not my area of expertise but I always thought it was multi-vendor. Lacking first-hand knowledge, a curious quick web search does imply that at least the Open/XA standard was supposed to be multi-vendor: The Open Grou

How heterogeneous do you mean? But basically, "yes". IBM had CICS transactions back in the day for some definition of heterogeneity. Tuxedo did this in the 80s across broader platforms. In the 90s (when I heard of it) there was a

Not exactly what I was looking for in terms of the security side of things but perhaps more sophisticated in terms of the editing handling. Cool, thanks for the reply! Money quote from https://mosh.org/#techinfo : Remote-

Does anyone know any SSH clients that support line-buffering of input? I.e. where what you type doesn't get transmitted until you hit or click return/send? I had one of these clients (but for telnet) back in more active MUD gaming

Err no, it was not just Juniper. Many other systems were fuzzed, half a dozen vendors were fine, another 5 weren’t and some remain unpatched and vulnerable. If it were just a Juniper implementation flaw it’d be less interesting than explain

The verbiage you cite makes it seem dull. I thought it was actually pretty interesting. The take away I got was that people whose fields are too similar don’t knowledge share and generate good knowledge creation nearly as well as situations

Thanks. Is there a list somewhere of Postgres-based columnar datastores (and which are MPP/clustered vs single/SMP-node)? * Citus (cstore_fwd) extension * Azure CosmosDB for PostgreSQL * GCP AlloyDB for PostgreSQL * AWS Redshift (

I hate to say it but certain advertisers might pay more for ads that play while people are sleeping (ie placement during 8 hour tracks of white noise). This is not a $38m-in-costs crisis for Spotify, this is a revenue opportunity! ... 60

Agreed. But you are 27 years late to this argument at least in the US. In 1996, when the Internet was hot, telcom providers promised to spend tens of billions building out fiber infra US-wide as long as Congress guaranteed them they owned

From the outside, their backend tech has loopholes they don’t notice that bleed money for them. I had a pair of modest-sized accounts with them that I didn’t use much. I kept them at $3000 to avoid hitting monthly minimums and paying fees.

I dunno, I used to use ISO linux images because they were write-once and assuming I had a trusted source of the ISO or system writing the ISO, I didn't have to worry about the Linux system getting compromised and I could just run Linux
