Data*lo2 1ask uses #uffer oriented architecture for data transfer and transformation!

$hen data transfer from Source to Destination, the data first comes into the #uffer,

required transformations are done in the #uffer itself and then 2ritten to Destination!

1he siFe of #uffer depends on the estimated ro2 siFe! 1he estimated ro2 siFe is equal to

the ma.imum siFe of all columns in the ro2! So the more columns in a ro2 means less

num#er of ro2s in a #uffer! ;ence select only those columns 2hich are required at the

destination!

0en if 2e need all the columns from source, 2e should use the column name specifically

in the S0=0"1 statement, other2ise it takes another round for the source to gather

meta-data a#out the columns 2hen u are using S0=0"1 !


21/82

! 0ffect of O=0DB Destination Settings

1here are couple of settings 2ith O=0DB destination 2hich can impact the performance

of data transfer as listed #elo2!

Data 6ccess Mode A 1his setting proides the /fast load/ option 2hich internally uses a

B?= INS01 statement for uploading data into the destination ta#le instead of a simple

INS01 statement for each single ro2C as in the case for other options! So unless youhae a reason for changing it, don/t change this default alue of fast load! If you select

the /fast load/ option, there are also a couple of other settings 2hich you can use as

discussed #elo2!

eep Identity A By default this setting is unchecked 2hich means the destination ta#le if

it has an identity columnC 2ill create identity alues on its o2n! If you check this setting,

the dataflo2 engine 2ill ensure that the source identity alues are presered and same

alue is inserted into the destination ta#le!

eep Nulls A 6gain #y default this setting is unchecked 2hich means default alue 2ill #e

inserted if the default constraint is defined on the target columnC during insert into the

destination ta#le if N?== alue is coming from the source for that particular column! If

you check this option then default constraint on the destination ta#le/s column 2ill #e

ignored and presered N?== of the source column 2ill #e inserted into the destination!

1a#le =ock A By default this setting is checked and the recommendation is to let it #e

checked unless the same ta#le is #eing used #y some other process at same time! It

specifies a ta#le lock 2ill #e acquired on the destination ta#le instead of acquiring

multiple ro2 leel locks, 2hich could turn into lock escalation pro#lems!

"heck "onstraints A 6gain #y default this setting is checked and recommendation is to

un-check it if you are sure that the incoming data is not going to iolate constraints of

the destination ta#le! 1his setting specifies that the dataflo2 pipeline engine 2ill alidatethe incoming data against the constraints of target ta#le! If you un-check this option it

2ill improe the performance of the data load!

5 - 0ffect of o2s %er Batch and Ma.imum Insert "ommit SiFe Settings&

o2s per #atch&

1he default alue for this setting is -) 2hich specifies all incoming ro2s 2ill #e treated as

a single #atch! @ou can change this default #ehaior and #reak all incoming ro2s into

multiple #atches! 1he allo2ed alue is only positie integer 2hich specifies the ma.imum

num#er of ro2s in a #atch!

Ma.imum insert commit siFe&

1he default alue for this setting is /()9:389/ largest alue for #yte integer typeC2hich specifies all incoming ro2s 2ill #e committed once on successful completion! @ou

can specify a positie alue for this setting to indicate that commit 2ill #e done for those

num#er of records! "hanging the default alue for this setting 2ill put oerhead on the

dataflo2 engine to commit seeral times! @es that is true, #ut at the same time it 2ill

release the pressure on the transaction log and tempd# to gro2 specifically during high

olume data transfers!

1he a#oe t2o settings are ery important to understand to improe the performance of

tempd# and the transaction log! *or e.ample if you leae /Ma. insert commit siFe/ to its

default, the transaction log and tempd# 2ill keep on gro2ing during the e.traction

process and if you are transferring a high olume of data the tempd# 2ill soon run out of


22/82

memory as a result of this your e.traction 2ill fail! So it is recommended to set these

alues to an optimum alue #ased on your enironment!

9 - DefaultBufferSiFe and DefaultBufferMa.o2s &

1he e.ecution tree creates #uffers for storing incoming ro2s and performing

transformations!

1he num#er of #uffer created is dependent on ho2 many ro2s fit into a #uffer and ho2

many ro2s fit into a #uffer dependent on fe2 other factors! 1he first consideration is the

estimated ro2 siFe, 2hich is the sum of the ma.imum siFes of all the columns from the

incoming records! 1he second consideration is the DefaultBufferMa.SiFe property of the

data flo2 task! 1his property specifies the default ma.imum siFe of a #uffer! 1he default

alue is )J MB and its upper and lo2er #oundaries are constrained #y t2o internal

properties of SSIS 2hich are Ma.BufferSiFe )JJMBC and MinBufferSiFe 8 BC! It

means the siFe of a #uffer can #e as small as 8 B and as large as )JJ MB! 1he third

factor is, DefaultBufferMa.o2s 2hich is again a property of data flo2 task 2hich

specifies the default num#er of ro2s in a #uffer! Its default alue is )JJJJ!

If the siFe e.ceeds the DefaultBufferMa.SiFe then it reduces the ro2s in the #uffer! *or

#etter #uffer performance you can do t2o things!

*irst you can remoe un2anted columns from the source and set data type in each

column appropriately, especially if your source is flat file! 1his 2ill ena#le you to

accommodate as many ro2s as possi#le in the #uffer!

Second, if your system has sufficient memory aaila#le, you can tune these properties to

hae a small num#er of large #uffers, 2hich could improe performance! Be2are if you

change the alues of these properties to a point 2here page spooling see Best %ractices

:C #egins, it adersely impacts performance! So #efore you set a alue for theseproperties, first thoroughly testing in your enironment and set the alues appropriately!

: - ;o2 Delay'alidation property can help you

SSIS uses t2o types of alidation!

*irst is package alidation early alidationC 2hich alidates the package and all its

components #efore starting the e.ecution of the package!

Second SSIS uses component alidation late alidationC, 2hich alidates the

components of the package once started!

=et/s consider a scenario 2here the first component of the package creates an o#Gect i!e!

a temporary ta#le, 2hich is #eing referenced #y the second component of the package!During package alidation, the first component has not yet e.ecuted, so no o#Gect has

#een created causing a package alidation failure 2hen alidating the second

component! SSIS 2ill thro2 a alidation e.ception and 2ill not start the package

e.ecution! So ho2 2ill you get this package running in this common scenarioT

1o help you in this scenario, eery component has a Delay'alidation defaultP*6=S0C

property! If you set it to 1?0, early alidation 2ill #e skipped and the component 2ill #e

alidated only at the component leel late alidationC 2hich is during package e.ecution

31/82

%ercentage Sampling transformation is generally used for data mining! 1his

transformation #uilds a random sample of set of output ro2s #y choosing specified

percentage of input ro2s! *or e.ample if the input has )JJJ ro2s and if I specify )J

as percentage sample then the transformation returns )JW of the 6NDOM records from

the input data!

$. hat is the use o" )erm 4traction trans"ormation in SSIS#1erm 0.traction transformation is used to e.tract nouns or noun phrases or #oth noun

and noun phrases only from 0nglish te.t! It e.tracts terms from te.t in a transformation

input column and then 2rites the terms to a transformation output column! It can #e

also used to find out the content of a dataset!

Multicast 1ransformation is used to e.tract output from single source and places onto

multiple destinations!

"onditional Split transformation is used for splitting the input data #ased on a specific

condition! 1he condition is ealuated in 'B Script!

Multicast 1ransformation generates e.act copies of the source data, it means each

recipient 2ill hae same num#er of records as the source 2hereas the "onditional Split

1ransformation diides the source data #ased on the defined conditions and if no ro2s

match 2ith this defined conditions those ro2s are put on default output!

What do we mean by datafow in SSIS?

Data flow is nothing but the flow of data from the corresponding sources to the referred

destinations. In this process, the data transformations make changes to the data to make it ready

for the data warehouse.

What is a breakpoint in SSIS? How is it setup? How do you disable

it?

A breakpoint is a stopping point in the code. The breakpoint can give the Developer\DBA an

opportunity to review the status of the data, variables and the overall status of the I package.

!" uni#ue conditions e$ist for each breakpoint.

Breakpoints are setup in BID. In BID, navigate to the control flow interface. %ight click on the

What is the use o 0ercentae Samplin transormation in SSIS?

6ercentage ampling transformation is generally used for data mining. This transformation builds

a random sample of set of output rows by choosing specified percentage of input rows. 3or

e$ample if the input has !""" rows and if I specify !" as percentage sample then the

transformation returns !" of the %A5D< records from the input data.

What is the use o "erm ,'traction transormation in SSIS?

Term ($traction transformation is used to e$tract nouns or noun phrases or both noun and noun

phrases only from (nglish te$t. It e$tracts terms from te$t in a transformation input column and


59/82

then writes the terms to a transformation output column. It can be also used to find out the

content of a dataset.

What is 4ata iewer and what are the di+erent types o 4ata

iewers in SSIS?A Data Eiewer allows viewing data at a point of time at runtime. If data viewer is placed before

and after the Aggregate transform, we can see data flowing to the transformation at the runtime

and how it looks like after the transformation occurred. The different types of data viewers are@
