Making sense of Big Data
with open source search

2. We build, tune and support fast, accurate and highly scalable
search, analytics and Big Data applications
We use (and create) open source software
We're independent, honest and have 15+ years experience
We also:
– Run and attend many events & conferences
– Write extensively about search & related matters
– Train and mentor

16. You could use (if you like writing code)
Apache
– Mature & stable & open development
– Huge list of features, plugins, integrations, resources...

17. You could use (if you like writing code)
Apache
– Mature & stable & open development
– Huge list of features, plugins, integrations, resources...
– Newer & funkier & open-ish
– Easier to get started with & an integrated stack

27. Sizing & scale
– The 50m rule of thumb
– 'It depends'
– Test & prototype
Things to consider
@FlaxSearch

28. Sizing & scale
– The 50m rule of thumb
– 'It depends'
– Test & prototype
Gotchas
– ES-Hadoop
– Fast moving ES APIs
– Memory & JVM tuning
– Distributed systems are hard
Things to consider

29. When real time isn't
– 'real time' often means 'faster indexing'
– Most streaming architectures end in a relatively static
index

Queries considered harmful
– Remember it's a search engine
– A bad query can kill your cluster
– Boolean that isn't
– Some big queries

32. Something clever...
@FlaxSearch

33. “The IoT has the potential to connect 10X as many (28 billion)
“things” to the Internet by 2020, ranging from bracelets to cars.”
Goldman Sachs1
“IoT threatens to generate massive amounts of input data from
sources that are globally distributed. Transferring the entirety
of that data to a single location for processing will not be
technically and economically viable” Gartner2
“Streaming analytics is anything but a sleepy, rearview mirror
analysis of data. No, it is about knowing and acting on what’s
happening in your business at this very moment — now.”
Forrester3
Analyst quotes
@FlaxSearch

34. Everything is a stream
“...think of a database as an always-growing collection of
immutable facts. You can query it at some point in time —
but that’s still old, imperative style thinking. A more fruitful
approach is to take the streams of facts as they come in, and
functionally process them in real-time”.- Martin Kleppman,

38. Flax solution scales to 1m queries over 1m items/day
We need to be faster:
– Network monitoring – up to 1m items/second
– Restaurant reservations/reviews – 840m messages/day
– IoT
Here's a prototype:
– https://github.com/romseygeek/samza-luwak
– “... you’ll be able to perform full-text search on streams at
arbitrary scale, simply by adding new partitions and
adding more machines to the cluster.” Martin Kleppman,
