In redshift we can have maxerror Option
df.write.option("url", jdbc_url) \
.option("dbtable", tbl) \
.option("tempdir", tmp_folder_rs) \
.option("aws_iam_role", rs_iam) \
.option("extracopyoptions", "**maxerror as 100000** blanksasnull") \
.mode("append") \
.save()
which gives it a tolerance of some records while loading.
Do we have similar options for MYSQL. My write to mysql is as below
job_status_event_req_cols.write.format("jdbc").option("url", "jdbc:mysql://test.us-west-1.vpce.amazonaws.com/test").option("driver", "com.mysql.jdbc.Driver").option("dbtable", "employee").option("user", "writer").option("password", "test").mode('append').save()

Scenario: I am putting together a repeatable script that creates, among other things, an Azure EventHub. My code looks like:
az eventhubs eventhub create \
--name [name] \
--namespace-name [namespace] \
--resource-group [group] \
--status Active \
--enable-capture true \
--archive-name-format "{Namespace}/{EventHub}/{Year}/{Month}/{Day}/{Hour}/{Minute}/{Second}/{PartitionId}" \
--storage-account [account] \
--blob-container [blob] \
--capture-interval 300 \
--partition-count 10 \
--skip-empty-archives true
If I run the code as written, I get a "Required property 'name' not found in JSON. Path 'properties.captureDescription.destination', line 1, position 527."
However, if I remove the --enable-capture true parameter, the EventHub is created, albeit with Capture not enabled. If I enable Capture, none of the capture-related parameters other than the interval are set.
Is there a typo in there that I'm not seeing?
Try providing the --destination-name.
az eventhubs eventhub create --name
--namespace-name
--resource-group
[--archive-name-format]
[--blob-container]
[--capture-interval]
[--capture-size-limit]
[--destination-name]
[--enable-capture {false, true}]
[--message-retention]
[--partition-count]
[--skip-empty-archives {false, true}]
[--status {Active, Disabled, SendDisabled}]
[--storage-account]
Im using MySQL server v5.8 as database, how to find median price in query like this:
price_query = Product.objects \
.filter(price_query) \
.annotate(dt=Trunc('StartDate', frequency)) \
.values('dt') \
.annotate(avg_price=Avg('Price'), std_price=StdDev('Price'),
count=Count('Price'), max_price=Max('Price'),
min_price=Min('Price'), median='???') \
.order_by('dt')
response is look like this
{"date":"2021-05-01T00:00:00Z","avg_price":4326.666666666667,"std_price":20.548046676563168,"min_price":4300.0, "max_price":4350.0,"count":3}, {...}, {...}
Any help is highly appreciated.
I want to link static jemalloc library for oracle mysql5.5 .If mysql5.1 ,i can do it :
LDFLAGS=” -lrt -ljemalloc -lstdc++ ”
./configure –prefix=/usr/soft/install/mysql \
–with-mysqld-user=mysql \
–with-plugins=partition,blackhole,csv,heap,innobase,myisam,myisammrg \
–with-charset=utf8 \
–with-collation=utf8_general_ci \
–with-extra-charsets=gbk,gb2312,utf8,ascii \

make && make install
But i can not find a cmake's option with it in mysql5.5.
What can i do?
We are trying to upgrade our MooTools installation from 1.2.4 to 1.2.6. The original developer included a "more" file with optional plugins, but because it is compressed we can't tell what was included in that file. I'd rather not hunt and pick through the code.
I noticed the compressed more file has a build hash in the header (6f6057dc645fdb7547689183b2311063bd653ddf). The 1.4 builder located here will let you just append that hash to the url and create a build. It doesn't seem the 1.2 version supports that functionality.
Is there an easy way to determine from the hash or the compressed file what plugins are included in this 1.2 build?
AFAIK there's no way to get the list of plugins directly from the build hash. But if you have access to a UNIX shell, save the following shell script as find_plugins.sh:
#!/bin/sh
for PLUGIN in \

do
grep -q -F $PLUGIN $1 && echo $PLUGIN
done
Then run it like this passing the filename of your MooTools More file as first argument:
sh find_plugins.sh mootools-more.js
It will print out a list of all plugin names found in the JS code. That should get you started.
I just wanna ask, what are those things called as "flags" in mysql ?
What are they, kindly explain and how they are used.
mysql flags are used by the compiler and set the enviroment you wish to work in.
There's flags such as:
'--with-archive-storage-engine'
wgich does what it states, it would start mysql process but also start the system in archive able content mode
Some more examples:
'--prefix=/usr/local/mysql' \
'--disable-dependency-tracking' \
'--enable-assembler' \
'--localstatedir=/usr/local/mysql/data' \
'--libexecdir=/usr/local/mysql/bin' \
'--libdir=/usr/local/mysql/lib' \
'--enable-local-infile' \
'--enable-shared' \
'--enable-thread-safe-client' \
'--with-archive-storage-engine' \
'--with-big-tables' \
'--with-comment=MySQL Community Server (GPL)' \
'--with-extra-charsets=complex' \
'--with-innodb' \
'--with-mysqld-ldflags=-all-static' \
'--with-readline' \
'--with-server-suffix=-standard' \
'--with-unix-socket-path=/tmp/mysql.sock' \
'--with-zlib-dir=bundled' \
'--without-debug' \
'--without-docs' \
'--without-man'
