Subject Re: [jira] [Created] (DRILL-6628) Possible incorporation of Twitter text processing UDFs into Drill-proper
Date Mon, 23 Jul 2018 15:39:58 GMT
Hi Bob, 
I was inspired a little by OSQuery and MySQL, but I’ve written a lot of UDFs that extend
basic SQL functionality and add other capabilities to Drill. IMHO, since Drill isn’t a database,
it really is a very helpful addition and will get more people using Drill.  I’d personally
be very interested in your Cyber-ish UDFs.  

FYI, there are a collection of Network analysis functions already in Drill:
Networking Functions
Drill supports the following networking functions to facilitate network analysis using Drill:


inet_aton(<ip>): Converts an IPv4 address into an integer
inet_ntoa( <int>): Converts an integer IP into dotted decimal notation
in_network( <ip>,<cidr> ): Returns true if the IP address is in the given CIDR
block
address_count( <cidr> ): Returns the number of IPs in a given CIDR block
broadcast_address( <cidr> ): Returns the broadcast address for a given CIDR block
netmask(<cidr> ): Returns the netmask for a given CIDR block
low_address(<cidr>): Returns the first address in a given CIDR block
high_address(<cidr>): Returns the last address in a given CIDR block
url_encode( <url> ): Returns a URL encoded string
url_decode( <url> ): Decodes ``a URL encoded string
is_valid_IP(<ip>): Returns true if the IP is a valid IP address
is_private_ip(<ip>): Returns true if the IP is a private IPv4 address
is_valid_IPv4(<ip>): Returns true if the IP is a valid IPv4 address
is_valid_IPv6(<ip>): Returns true if the IP is a valid IPv6 address

I’ve been working on a few other security related hackery including Drill UDFs that do DNS
lookups and Whois data.  Also, I assume you saw that Drill-6104 which is a generic regex/log
format plugin.  I’m working on a syslog/RFC-5424 format plugin for Drill which I intend
to submit for Drill 1.15.  Anyway, my point being IMHO, Drill is a great tool for cyber data
analysis and the more goodness we have officially part of Drill the better things are. 

Best,
—C

there's precedent for inclusion of "non-boring-SQL"-like functions into Drill-proper. On the
other hand, this is a small addition of a handful of functions for Twitter text so would this
be to niche for a "Twitter"  function group?

tree and gladly machinate the necessary changes/inclusions if the result of this discussion
results in that decision.
