> Consider removing date formatting from Segments class
> -----------------------------------------------------

> Key: KAFKA-5515

> Project: Kafka
> Issue Type: Improvement
> Components: streams

> Currently the {{Segments}} class uses a date when calculating the segment id
> and uses {{SimpleDateFormat}} for formatting the segment id. However this is
> a high volume code path and creating a new {{SimpleDateFormat}} and
> formatting each segment id is expensive. We should look into removing the
> date from the segment id or at a minimum use a faster alternative to
> {{SimpleDateFormat}}. We should also consider keeping a lookup of existing
> segments to avoid as many string operations as possible.
