* Narrow mutex scope when interacting with HDFS. Related to [#35292](https://github.com/ClickHouse/ClickHouse/issues/35292). [#35646](https://github.com/ClickHouse/ClickHouse/pull/35646) ([shuchaome](https://github.com/shuchaome)).
* Require mutations for per-table TTL only when it had been changed. [#35953](https://github.com/ClickHouse/ClickHouse/pull/35953) ([Azat Khuzhin](https://github.com/azat)).
#### Improvement
* Multiple improvements for schema inference. Use some tweaks and heuristics to determine numbers, strings, arrays, tuples and maps in CSV, TSV and TSVRaw data formats. Add setting `input_format_csv_use_best_effort_in_schema_inference` for CSV format that enables/disables using these heuristics, if it's disabled, we treat everything as string. Add similar setting `input_format_tsv_use_best_effort_in_schema_inference` for TSV/TSVRaw format. These settings are enabled by default. - Add Maps support for schema inference in Values format. - Fix possible segfault in schema inference in Values format. - Allow to skip columns with unsupported types in Arrow/ORC/Parquet formats. Add corresponding settings for it: `input_format_{parquet|orc|arrow}_skip_columns_with_unsupported_types_in_schema_inference`. These settings are disabled by default. - Allow to convert a column with type Null to a Nullable column with all NULL values in Arrow/Parquet formats. - Allow to specify column names in schema inference via setting `column_names_for_schema_inference` for formats that don't contain column names (like CSV, TSV, JSONCompactEachRow, etc) - Fix schema inference in ORC/Arrow/Parquet formats in terms of working with Nullable columns. Previously all inferred types were not Nullable and it blocked reading Nullable columns from data, now it's fixed and all inferred types are always Nullable (because we cannot understand that column is Nullable or not by reading the schema). - Fix schema inference in Template format with CSV escaping rules. [#35582](https://github.com/ClickHouse/ClickHouse/pull/35582) ([Kruglov Pavel](https://github.com/Avogar)).
