@javarevisited Database is 100% means all the queries are hitting the database that means there is something wrong in cache . Check the cache and fix it . And also check the query whether the queries are taking long time to execute

@Zinny_Edmund Cd - change directory

@tanujDE3180 Concurrency managing multiple tasks that make progress during overlapping time periods. whereas parallelism means multiple tasks are executing together

@0xPrajwal_ Encoding means changing the data format , where as encryption means transforming the data into cipher text with a key or algorithm for secure data transfer

[Myself @myself__alien]

@BuildWithOm In production the data might be huge and may not match the features with training data

[Myself @myself__alien]

@yashmp2004 Check the database , the connection pool may exhausted, to avoid this use indexes ( composite or single ) on columns and store the hot keys in Cache

@ayesha_fatiima Using bloom filters , instagram scans the username column and also the column is indexed so it will be O(1) operation

@EOEboh Wrong index is dangerous compared to missing index.

[Myself @myself__alien]

@dark_coderz Add the index to the email column so that the query time will be reduced

[Myself @myself__alien]

@Its_Nova1012 We need to ensure that we are sending the same idempotent key in the frontend so that backend recognises the key and charge the user only once

[Myself @myself__alien]

@CaptainInsightX The locking mechanism is missing here .

@SahilExec For duplicates handling we need to implement idempotency and for the error handle we don't commit the message offset automatically.

[Myself @myself__alien]

@ritu_twts I will design the DB schema along with backend

[Myself @myself__alien]

@tanujDE3180 For 12 partitions and 3 consumers - all consumers will read in parallel only .

If we add 15 consumers then the 3 will stay idle

[Myself @myself__alien]

@javarevisited When the traffic is high , we need to protect the DB so the caching is so important
