    • Attribute Value
    Type BOOLEAN
    Nillable true
    Expressions Allowed false

    Storage runtime
    Access Type metric
  • level logger level (see javadocs)
    • Attribute Value
    Type STRING
    Nillable true
    Expressions Allowed false
    Storage runtime
    Access Type metric
  • max_block_time Max time (in ms) to block
    • Attribute Value
    Type LONG
    Nillable true
    Expressions Allowed false
