In this example, the RowKey consists of the day and time from the log concept to make certain log messages are stored sorted in date/time buy, and includes a concept id in the event multiple log messages share exactly the same day and time.
Empower the deletion of the large quantity of entities by storing all the entities for simultaneous deletion in their unique different table; you delete the entities by deleting the table. Context and difficulty
This implies that you need to retail outlet all copies of the entity in precisely the same partition. For more info, begin to see the part Applying Entity Team Transactions. The value employed for the RowKey has to be one of a kind for each entity. Consider using compound essential values. Padding numeric values from the RowKey (as an example, the worker id 000223), permits right sorting and filtering based on upper and reduced bounds. You do not essentially have to replicate all the Houses of the entity. As an example, If your queries that lookup the entities using the email tackle while in the RowKey hardly ever will need the employee's age, these entities might have the subsequent framework:
Use this pattern when you want in order to avoid exceeding the partition scalability restrictions if you are executing entity lookups using the various RowKey values. Relevant patterns and guidance

The opposite important variable that influences your alternative of keys for optimizing information modifications is how to guarantee consistency by using atomic transactions. You can only use an EGT to work on entities stored in the same partition. The subsequent patterns during the portion Table Structure Designs tackle handling consistency: Intra-partition secondary index sample - Retail store many copies of every entity applying distinctive RowKey values (in a similar partition) to help quick and economical lookups and alternate form orders by utilizing diverse RowKey values.
You are able to apply a queue-dependent solution that provides eventual consistency (begin to see the Ultimately dependable transactions pattern For additional facts). When to utilize this sample
