repository/src/main/java/org/apache/atlas/repository/store/graph/v2/AtlasGraphUtilsV2.java Line 118 (original), 119 (patched) <https://reviews.apache.org/r/73453/#comment312324> For type hive_table, this would change the prefix from "__hive_table" => "__attribute.hive_table". I suggest to use following prefix: "__hive_table._attr". Note that attribute names in struct/entity/classification/relationship can't begin with a leading underscore; hence use of prefix "_attr" is safe. public static final String ATTRIBUTE_PREFIX = "._attr"; public static String getTypeDefPropertyKey(String typeName) { return PROPERTY_PREFIX + typeName + ATTRIBUTE_PREFIX; } public static String getTypeDefPropertyKey(String typeName, String child) { return PROPERTY_PREFIX + typeName + ATTRIBUTE_PREFIX + "." + child; } - Madhan Neethiraj On July 12, 2021, 2:41 p.m., Nixon Rodrigues wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
