This contains many fixes and corrections for the Kafka engine.
Most notably it now supports extended configuration similarly to GraphiteMergeTree.
Now it also allows specification of consumer count to parallelize consumption of
multiple partitions both in materialized views and in SELECT queries.
The offsets are now committed in the insertSuffix() method after all rows
are successfully read. If an exception is thrown during reading, affected consumer
unsubscribes from all assignments and rejoins the consumer group to rewind offsets.
This means that the consumer won't lose messages in case of write failures.
This addresses one of the remarks in the PR.
All format schemas are required to be in the <format_schema_path> directory.
This makes loading schema files less tedious, as the path can be omitted.
Cap'n Proto is a binary message format.
Like Protocol Buffers and Thrift (but unlike JSON or MessagePack), Cap'n Proto messages are strongly-typed and not self-describing. Due to this, it requires a schema setting to specify schema file and the root object. The schema is parsed on runtime and cached for each SQL statement.
By default sum(x) promotes the result type to
largest possible integral type to avoid
arithmetic overflow when summing values from
smaller data types.
This is generally desirable behaviour, but it doesn’t
work with summing merge tree, as the result is
expected to be of same type as the input.
Allow `ATTACH TABLE [db.]name` if the table was previously detached,
an the table structure can be read from disk. This makes reattaching
tables less cumbersome:
```
CREATE TABLE test.t (x UInt8) ENGINE = Null;
DETACH TABLE test.t;
ATTACH TABLE test.t;
```
This allows creation of materialized views without inner tables,
using an existing table for materialized rows instead.
This is useful for cases when you want to detach the materializing
view, but keep the already materialized data readable, especially
when the inner table is replicated.
