.SYNOPSIS
    Get detailed information about In-Memory SQL Server objects

.DESCRIPTION
    Get detailed information about In-Memory SQL Server objects
    Tested on SQL Server: 2014, 2016, 2017
    tested on Azure SQL Database
    NOT tested on Azure Managed Instances

.PARAMETER @instanceLevelOnly
    Only check instance In-Memory related information

.PARAMETER @dbName
    Check database In-Memory objects for specified database

.PARAMETER @tableName
    Check database In-Memory objects for specified tablename

.PARAMETER @debug
    Only PRINT dynamic sql statements without executing it

.EXAMPLE
    EXEC sp_BlitzInMemoryOLTP;
    -- Get all In-memory information

.EXAMPLE
    EXEC sp_BlitzInMemoryOLTP @dbName = N'ಠ ಠ';
    -- Get In-memory information for database with name ಠ ಠ

.EXAMPLE
    EXEC sp_BlitzInMemoryOLTP @instanceLevelOnly = 1;
    -- Get only instance In-Memory information

.EXAMPLE
    EXEC sp_BlitzInMemoryOLTP @debug = 1;
    -- PRINT dynamic sql statements without executing it

                From BOL:

                Empty buckets:
                    33% is a good target value, but a larger percentage (even 90%) is usually fine.
                    When the bucket count equals the number of distinct key values, approximately 33% of the buckets are empty.
                    A value below 10% is too low.

                Chains within buckets:
                    An average chain length of 1 is ideal in case there are no duplicate index key values. Chain lengths up to 10 are usually acceptable.
                    If the average chain length is greater than 10, and the empty bucket percent is greater than 10%, 
                    the data has so many duplicates that a hash index might not be the most appropriate type.

            all other SQL Server memory is allocated from.

            NOTE #2: if you want to bind a memory-optimized database to resource pool, 
            the database must be taken OFFLINE/ONINE for the binding to take effect. 
            This will cause all durable data to be removed from memory, and re(streamed)
