Method GetPartitionID

pkg/consistent/consistent.go:367–373

GetPartitionID calculates and returns the partition ID for a given key. The partition ID is determined by hashing the key and applying modulo operation with the partition count.

(key []byte)

// GetPartitionID calculates and returns the partition ID for a given key.
// The partition ID is determined by hashing the key and applying modulo operation with the partition count.
func (c *Consistent) GetPartitionID(key []byte) int {
	// Generate a hash value for the given key using the configured hasher.
	hashValue := c.hasher(key)

	// Calculate the partition ID by taking the modulus of the hash value with the partition count.
	return int(hashValue % c.partitionCount)
}

// GetPartitionOwner retrieves the owner of the specified partition in a thread-safe manner.
// It ensures that the access to shared resources is synchronized.
