Is it always necessary that the NA partition will be on a storage rack different from AP? I mean it’s possible that both are unavailable right? Also what if I have a process that requires both the NA and AP data at the same time? Will it impact the process?

[@modernphysco7436]

I have partition in my table say by year(2011,2012...2018). And i need to update an single row in 2011 partition,and insert a row in 2011 partition , how can i do this.

[@TechCoach]

Your DML code does not change for a partitioned table, you can update and insert the way you have done for a normal table.Oracle will take care of the rest

[@sukritsen9530]

Hello, I have a question, how can we partition on a column which has timestamp data, how can I partition that column for year or month granularity??

[@TechCoach]

Good question, there are multiple ways to do it. You can look at range or interval partitioning. If you want to use list partitioning, you can derive columns from timestamp column and use partitioning on the derived column. Please let me know if it helps.

[@sukritsen9530]

Thank You Tech Coach for your prompt response, I have gone through the videos and concepts of Partitioning, Materialised Views and Indexes. I am confused as to which one has to be used in which situation if we have a billion records. All of them seem to be inter-usable. Can you please explain the conditions in which each has to be used?

[@TechCoach]

Sukrit there are 2 basic things we should understand. If we want to access a major chunk of data frequently from a big table like more than 10% then partitioning will help. ( partition pruning is the reason). If you want to access very minor chunk from a table ( indexing will help). Now you can leverage indexing and partitioning together to have high performance systems. For example, a telecom company would access monthly data frequently to generate bills. So it makes more sense to partition on month column. In extension to that you might want to query individual customer transactions frequently for a month. So you can create an index on top of partitioning. I hope this clarifies your doubts.

[@shrijeetshivdekar9076]

When we define by region, clear differentiation through segments If we have to retrieve days for a emea, it scans segment of region, full partition scan done rather than full table scan This simpler handling of huge amount of data Transaction table for billions of rows:

[@shrijeetshivdekar9076]

When we want rolling 3 years of data, we care only about data of last 3 years, and we don't care about days before it Deleting billions of rows will take forever 2nd option :partitioning based on year! This deleting is simpler

[@shrijeetshivdekar9076]

Partitioning allows tables to be subdivided into smaller pieces, we get better granularity

[@shrijeetshivdekar9076]

January February match April and may Only new data from may is editable We cannot go back in time and edit For previous months, data is read only This partitioning on basis of month will make our job very easy. We No need to backup pe restore for previous months! This reduces time by a huge margin. The backup is going to take very less time. This better manageability of data

[@shrijeetshivdekar9076]

Na partition unavailable If non partitioned, then we would have not been able to work However, because it is available, thus we can work despite power failure

[@shrijeetshivdekar9076]

Fir database larger than terabytes, we need partitions.

how can i partition based on a uuid in oracle?

[@AnIndianAbroadd]

What kind of partitioning you want sanjay, I am guessing you want to divide the data in equal partitions using the key. I would recommend hash partitoning for that.
