org.elasticsearch.xpack.esql.datasources.cache.ListingCacheKey
public record ListingCacheKey(String scheme, String bucketOrContainer, String prefixAndGlob, String endpoint, String region, long credentialHashH1, long credentialHashH2) extends Record
Cache key for file listing results. Includes a 128-bit Murmur3 hash of credential values (NOT the credential keys) for isolation between users with different credentials. Endpoint and region are included because the same bucket on different endpoints contains different objects.

  • Method Details

    • build

      public static ListingCacheKey build(String scheme, String bucket, String prefixAndGlob, Map<String,Object> config)

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
