// This operation is not supported for directory buckets.
//
// This action filters the contents of an Amazon S3 object based on a simple
// structured query language (SQL) statement. In the request, along with the SQL
// expression, you must also specify a data serialization format (JSON, CSV, or
// Apache Parquet) of the object. Amazon S3 uses this format to parse object data
// into records, and returns only records that match the specified SQL expression.
// You must also specify the data serialization format for the response.
//
// This functionality is not supported for Amazon S3 on Outposts.
//
// For more information about Amazon S3 Select, see [Selecting Content from Objects] and [SELECT Command] in the Amazon S3 User
// Guide.
//
// Permissions You must have the s3:GetObject permission for this operation.
// Amazon S3 Select does not support anonymous access. For more information about
// permissions, see [Specifying Permissions in a Policy]in the Amazon S3 User Guide.
//
// Object Data Formats You can use Amazon S3 Select to query objects that have the
// following format properties:
//
//   - CSV, JSON, and Parquet - Objects must be in CSV, JSON, or Parquet format.
//
//   - UTF-8 - UTF-8 is the only encoding type Amazon S3 Select supports.
//
//   - GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP or BZIP2.
//     GZIP and BZIP2 are the only compression formats that Amazon S3 Select supports
//     for CSV and JSON files. Amazon S3 Select supports columnar compression for
//     Parquet using GZIP or Snappy. Amazon S3 Select does not support whole-object
//     compression for Parquet objects.
//
//   - Server-side encryption - Amazon S3 Select supports querying objects that
//     are protected with server-side encryption.
//
// For objects that are encrypted with customer-provided encryption keys (SSE-C),
//
//	you must use HTTPS, and you must use the headers that are documented in the [GetObject].
//	For more information about SSE-C, see [Server-Side Encryption (Using Customer-Provided Encryption Keys)]in the Amazon S3 User Guide.
//
// For objects that are encrypted with Amazon S3 managed keys (SSE-S3) and Amazon
//
//	Web Services KMS keys (SSE-KMS), server-side encryption is handled
//	transparently, so you don't need to specify anything. For more information about
//	server-side encryption, including SSE-S3 and SSE-KMS, see [Protecting Data Using Server-Side Encryption]in the Amazon S3
//	User Guide.
//
// Working with the Response Body Given the response size is unknown, Amazon S3
// Select streams the response as a series of messages and includes a
// Transfer-Encoding header with chunked as its value in the response. For more
// information, see [Appendix: SelectObjectContent Response].
//
// GetObject Support The SelectObjectContent action does not support the following
// GetObject functionality. For more information, see [GetObject].
//
//   - Range : Although you can specify a scan range for an Amazon S3 Select
//     request (see [SelectObjectContentRequest - ScanRange]in the request parameters), you cannot specify the range of
//     bytes of an object to return.
//
//   - The GLACIER , DEEP_ARCHIVE , and REDUCED_REDUNDANCY storage classes, or the
//     ARCHIVE_ACCESS and DEEP_ARCHIVE_ACCESS access tiers of the INTELLIGENT_TIERING
//     storage class: You cannot query objects in the GLACIER , DEEP_ARCHIVE , or
//     REDUCED_REDUNDANCY storage classes, nor objects in the ARCHIVE_ACCESS or
//     DEEP_ARCHIVE_ACCESS access tiers of the INTELLIGENT_TIERING storage class. For
//     more information about storage classes, see [Using Amazon S3 storage classes]in the Amazon S3 User Guide.
//
// Special Errors For a list of special errors for this operation, see [List of SELECT Object Content Error Codes]
//
// The following operations are related to SelectObjectContent :
//
// [GetObject]
//
// [GetBucketLifecycleConfiguration]
//
// [PutBucketLifecycleConfiguration]
//
// You must URL encode any signed header values that contain spaces. For example,
// if your header value is my file.txt , containing two spaces after my , you must
// URL encode this value to my%20%20file.txt .
