Hpts'17 24-Hour Interval 1
This postal service is a continuation from yesterday's post. I comprehend entirely some of the talks, you may cheque the other talks from the HPTS agenda.
| fast-reads | fast-writes | read-your-write
linearizable | no | no | yes
nonlinearizable | yes | yes | no
cached-data | yes | no | no
The indicate is yous can't guide maintain everything. Pat argues "immutability is a company stone to stand upwards on" too is the closest yous tin larn to yes, yes, yes, inward that table. However, Pat cautions that what matters is non hitting yes, yes, yes on that table. Don't autumn inward honey amongst whatsoever of those consistency semantics, what matters is the application requirements. Different applications need dissimilar behaviors from durable state: Do yous desire it right or right now?
Here is Pat's presentation slides.
His principal indicate was that companies already guide maintain their workflows/toolchains streamlined on a cloud vendor too compared to the simplicity of integrating an existing service from the cloud vendor to their workflows/toolchains, it is an uphill-battle to overcome when integrating a third political party to their workflow. Ain't nobody got fourth dimension for that.
His other points were:
These are fair points, but I intend his speak should instead last making the reverse point: things are dire for the infrastructure startups when facing the cloud vendors, too then how tin nosotros help/encourage them? At 1 indicate inward his talk, he mentioned that their companionship used entirely 1 exterior vendor, the datadog, because google cloud hiked upwards the prices on its monitoring service. This shows that nosotros should last rooting for the success of infrastructure services/companies too then that the cloud vendors don't grab all mightiness against the developers.
Moreover Evan's points don't accept into draw of piece of occupation organization human relationship enterprise markets too also unusual markets similar Europe too China. Infrastructure companies create be because at that spot is marketplace seat for them. Several infrastructure/databases companies guide maintain done actually cracking financially, too I promise nosotros volition run into to a greater extent than success stories from them inward the futurity equally well.
The speak gave a quick overview of CockroachDB's scale-out architecture to implement a WAN distributed SQL database service. When edifice CockroachDB the squad prioritized correctness too stability over performance, too attacked those first. They are instantly working on functioning improvements too achieving scale-out OLTP. Arjun talked virtually how HTAP tin last done over CockroachDB inward the future. He likes to leverage on the CockroachDB OLTP layer too adopt incrementally updated materialized views equally the edifice primitive. Concretely, he argues that since CockroachDB timestamps arrive at serializable transactions that bridge OLTP+OLAP, it is possible to create dataflow systems similar Naiad or timely dataflow for achieving HTAP.
There were many interesting talks inward the gong session. And amongst v minutes per talk, they were fast-paced equally well.
Joy also convinced me to acquaint at the gong demonstrate at to a greater extent than or less noon, too then I had to write some slides inward the afternoon. Thanks to the emacs-org-mode export to beamer I was able to come upwards up amongst slides inward fourth dimension for the talk. I presented virtually our ongoing locomote on wPaxos, our WAN Paxos protocol. I volition last writing a spider web log postal service virtually that onetime soon.
Mind your state for your state of heed (Pat Helland -Salesforce)
HPTS solar daytime 1 started amongst a keynote from Pat Helland. Pat Helland is a database veteran. I had covered some of his papers on this spider web log before. He writes insightful seat papers amongst a unique style. The keynote provided an overview of trends inward storage too computing too striking the high notes from his before seat papers equally well, too mentioned this table:| fast-reads | fast-writes | read-your-write
linearizable | no | no | yes
nonlinearizable | yes | yes | no
cached-data | yes | no | no
The indicate is yous can't guide maintain everything. Pat argues "immutability is a company stone to stand upwards on" too is the closest yous tin larn to yes, yes, yes, inward that table.

Here is Pat's presentation slides.
Stop edifice infrastructure (Evan Jones, Bluecore)
Evan started the presentation amongst a disclosure: warning: zip facts ahead. This was sign that this volition last a deliberately provocative/controversial position. He argued that developers should halt edifice infrastructure (i.e., databases, charge balancers, service orchestration software).His principal indicate was that companies already guide maintain their workflows/toolchains streamlined on a cloud vendor too compared to the simplicity of integrating an existing service from the cloud vendor to their workflows/toolchains, it is an uphill-battle to overcome when integrating a third political party to their workflow. Ain't nobody got fourth dimension for that.
His other points were:
- the cloud vendors are ameliorate at edifice infrastructure than you
- even if yous succeed, your infrastructure is going to run at cloud, too volition brand coin to the cloud vendors
- cloud vendors tin destroy yous via re-create too crush
- at a companionship it is slow to justify paying an existing cloud vendor, but it is cumbersome to convince administration to purchase third political party software
These are fair points, but I intend his speak should instead last making the reverse point: things are dire for the infrastructure startups when facing the cloud vendors, too then how tin nosotros help/encourage them? At 1 indicate inward his talk, he mentioned that their companionship used entirely 1 exterior vendor, the datadog, because google cloud hiked upwards the prices on its monitoring service. This shows that nosotros should last rooting for the success of infrastructure services/companies too then that the cloud vendors don't grab all mightiness against the developers.

Infrastructure companies create be because at that spot is marketplace seat for them. Several infrastructure/databases companies guide maintain done actually cracking financially, too I promise nosotros volition run into to a greater extent than success stories from them inward the futurity equally well.
Blockchain too Databases - C Mohan (IBM)
Mohan gave an overview of blockchain too talked virtually the HyperLedger project. His talk(s) too to a greater extent than information tin last establish at http://bit.ly/CMbcDB.CockroachDB: From OLTP to HTAP - Arjun Narayan (Cockroach Labs)
Here are the slides for the talk. OLTP stands for online transaction processing, too HTAP stands for hybrid transactional/analytical processing.The speak gave a quick overview of CockroachDB's scale-out architecture to implement a WAN distributed SQL database service. When edifice CockroachDB the squad prioritized correctness too stability over performance, too attacked those first. They are instantly working on functioning improvements too achieving scale-out OLTP. Arjun talked virtually how HTAP tin last done over CockroachDB inward the future. He likes to leverage on the CockroachDB OLTP layer too adopt incrementally updated materialized views equally the edifice primitive. Concretely, he argues that since CockroachDB timestamps arrive at serializable transactions that bridge OLTP+OLAP, it is possible to create dataflow systems similar Naiad or timely dataflow for achieving HTAP.
Gongshow
After the dinner, nosotros gathered at the chapel for a potpourri of v infinitesimal talks. Andy Pavlo's educatee Joy Arulraj organized the session. (Joy volition last on the academic chore market too he volition last a cracking grab for whoever manages to hire him.)There were many interesting talks inward the gong session. And amongst v minutes per talk, they were fast-paced equally well.
Joy also convinced me to acquaint at the gong demonstrate at to a greater extent than or less noon, too then I had to write some slides inward the afternoon. Thanks to the emacs-org-mode export to beamer I was able to come upwards up amongst slides inward fourth dimension for the talk. I presented virtually our ongoing locomote on wPaxos, our WAN Paxos protocol. I volition last writing a spider web log postal service virtually that onetime soon.
