sql - COPY data from S3 to RedShift in python (sqlalchemy) -


i'm trying push (with copy) big file s3 redshift. im using sqlalchemy in python execute sql command looks copy works if preliminary truncate table.

the connection works ok:

from sqlalchemy import create_engine  engine = create_engine('postgresql://xxxx:xxxx@xxxx:xxxx/xxxx')

with command string (if truncate table before copy command)

toredshift = "truncate table public.my_table; copy public.my_table 's3://xxxx/part-p.csv' credentials 'aws_access_key_id=aaaaaaa;aws_secret_access_key=bbbbbbb' gzip removequotes ignoreheader 0 delimiter '|';" engine.execute(toredshift)

if remove "truncate table public.my_table;" bit 

toredshift = "copy public.my_table 's3://xxxx/part-p.csv' credentials 'aws_access_key_id=aaaaaaa;aws_secret_access_key=bbbbbbb' gzip removequotes ignoreheader 0 delimiter '|';" engine.execute(toredshift)

but command works in other sql client (like dbeaver example)

thank ilja. command works:

engine.execute(text(toredshift).execution_options(autocommit=true))

i don't know why able push data truncate bit @ front of string.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
