When I create a uberjar with aot compilation I am surprised to see ".clj"
files in there. Then when I run the jar with the "java -jar myuberjar"
command I get a ClassNotFoundException.
For example, I am have the following dependency in my project.clj file:
[org.clojure/java.jdb
Can someone help me write the following function:
I have two lists of maps as inputs:
(def xs [{:id 1 :val 10}
{:id 2 :val 20}
{:id 3 :val 30}
{:id 4 :val 40}])
(def ys [{:id 2 :val 20}
{:id 3 :val 30}
{:id 5 :val 50}
Peter/Tim -
Also want to commend you on this amazing high performant library (deep-
freeze) that you have written.

Thanks a lot Peter. Worked great! I did some rudimentary bench marking
for large data sets and found deep-freeze to be 10 times faster on
average compared to JSON serialization. That is really a huge
performance difference.

Hi Tim
I am using redis-clojure client: https://github.com/tavisrudd/redis-clojure

Hi Peter -
I looked at deep-freeze but did not quite understand how to use it.
I used the following to freeze my Clojure complex data structure -
results (map of list of maps) and persist to redis:
(redis/hmset k k (deep-freeze/freeze-to-array results))
Then I tried to retrieve and thaw it as
pr-str or

I am trying to use Redis as a data structure cache for my clojure
application. Does anybody have experience/code/ideas that can write/
read a clojure complex data structure to the Redis cache.
For example I have a list of maps as shown below:
(def m1
[{
"total" {:end_mv_base 721470021.02M, :r
I want to merge lists of maps. Each map entry has an :id and :code
key. The code associated to :id from one map should have higher
precedence than the same :id entry from another map.
I have an implementation. The problem and solution is best described
using example:
;priority 1 map
(def p1 [{:i
Is there a more elegant/idomatic way to achieve the following result:
user=> a1
["a" "b" "c" "d"]
user=> (map-indexed (fn [n x] (vec (take (inc n) x))) (take (count a1)
(repeat a1)))
(["a"] ["a" "b"] ["a" "b" "c"] ["a" "b" "c" "d"])

Hi
I wrote the following function to create a SQL IN clause from a list
of values. Essentially the function creates a single string which is a
comma separated quoted list of the values surrounded by parenthesis.
user=> (def xs [1 2 3 4 5])
user=>(str "('" (first xs) (reduce #(str %1 "', '" %2) "
Thanks. Didn't think it would exist in clojure.core.

Many thanks for adding this feature. Without it the Clojure code would
have been left in the dust.

Hi Sean –
With these options added the Clojure code runs just about as fast as
Java. I set the fetch size to 1000 for both of them.
Average run times to load 69,000 records:
Java = 2.67 seconds
Clojure = 2.72 seconds
Thanks

My apologies to the group. I found out why my Clojure code runs slower
than Java.
The Java code uses the setFetchSize() method to retrieve data in
batch:
myResultSet.setFetchSize(1000);
myResultSet.setFetchDirection(ResultSet.FETCH_FORWARD);

You are right Michael. I misunderstood Colin's statement.
As Stuart suggested I am profiling the code and will share the results
with the group soon.

I switched to clojure.java.jdbc. Found no difference at all. It is
still about 10 times slower than java.

I am loading about 100,000 records from the database with
clojure.contrib.sql, using a simple query that pulls in 25 attributes
(columns) per row. Most of the columns are of type NUMBER so they get loaded
as BigDecimals. I am using Oracle database and the jdbc 6 driver (
com.oracle/ojdbc6 "11.1.0.7
Problem summary: I am running out of memory using pmap but the same code
works with regular map function.
