This patchset introduces functional indexes in memtx.
Functional index is an index that use user-defined function to extract
a key by tuple.
In current implementation only persistent deterministic sandboxed Lua
function previously created with box.schema.func.create may be used
in functional index.
This provides a potential ability to support new languages to
transparently extend supported extractors in future (e.g. SQL extractor,
C extractor).
Because an _index space is loaded before _func space, functional index
initially created in "disabled state". Then, on loading from a new space
_func_index, it completely rebuilds.
Comment:
- I'll send a follow-up patch to specify function by name a bit later.
Changes in version 4:
- functional indexes are implemented with memtx_tree vtab like
version 1 did
- index object doesn't use hash at all

Introduced a new object tuple_chunk: a memory allocation is
associated with given tuple. tuple_format's vtab is extended
with few new methods to manage tuple_chunks lifecycle.
Implemented corresponding methid for memtx engine: a memory
chunks are allocated with memtx's smalloc allocator.
Needed for #1260

Updated multikey memtx_tree methods a bit to make possible to
reuse them in case of functional indexes. The BPS_TREE_IDENTICAL
is only used in bps_tree_delete_identical (when BPS_TREE_NO_DEBUG
macro is defined) therefore it may be reused to delete an
identical entry in case of functional index in further patches.
Needed for #1260

Renamed memtx_tree_delete_identical to memtx_tree_delete_value
because it is more representative name. Changed it's signature
to return a deleted item, because it may require following
destruction.
This refactoring is required in scope of functional indexes.

Closes #1260
@TarantoolBot document
Title: introduce functional indexes in memtx
Now you can define a functional index using registered persistent
function as key extractor.
There is some restrictions for function and key definition for
functional index:
- referenced function must be persistent, deterministic
and must return scalar type or array.
- key parts describe the referenced routine's returned key
(when the routine returned value type is array in meaning of
multikey index key): all parts must be sequential and the
first part's fieldno must be 1.
- key parts can't use JSON paths.
- you are not allowed to access tuple fields by names in function
Functional index can't be primary.
You are not allowed to change functional index extractor function
while there are some functional indexes depends of it.
To define a functional multikey index, just return multiple values
from function. Each value (even when it is a single scalar must
be returned as table i.e. {1}) and must follow functional index
key definition.
Example:
s = box.schema.space.create('withdata')
s:format({{name = 'name', type = 'string'},
{name = 'address', type = 'string'}})
pk = s:create_index('name', {parts = {1, 'string'}})
lua_code = [[function(tuple)
local address = string.split(tuple[2])
local ret = {}
for _, v in pairs(address) do
table.insert(ret, {utf8.upper(v)})
end
return unpack(ret)
end]]
box.schema.func.create('addr_extractor', {body = lua_code,
is_deterministic = true, is_sandboxed = true})
idx = s:create_index('addr', {unique = false,
func = box.func.addr_extractor.id,
parts = {{1, 'string', collation = 'unicode_ci'}}})
s:insert({"James", "SIS Building Lambeth London UK"})
s:insert({"Sherlock", "221B Baker St Marylebone London NW1 6XE UK"})
idx:select('Uk')

Title: introduce functional indexes in memtx
Now you can define a functional index using registered persistent
function as key extractor.
There is some restrictions for function and key definition for
functional index:
- referenced function must be persistent, deterministic
and must return scalar type or array.
- key parts describe the referenced routine's returned key
(when the routine returned value type is array in meaning of
multikey index key): all parts must be sequential and the
first part's fieldno must be 1.
- key parts can't use JSON paths.
- you are not allowed to access tuple fields by names in function
Functional index can't be primary.
You are not allowed to change functional index extractor function
while there are some functional indexes depends of it.
To define a functional multikey index, just return multiple values
from function. Each value (even when it is a single scalar must
be returned as table i.e. {1}) and must follow functional index
key definition.
Example:
s = box.schema.space.create('withdata')
s:format({{name = 'name', type = 'string'},
{name = 'address', type = 'string'}})
pk = s:create_index('name', {parts = {1, 'string'}})
lua_code = [[function(tuple)
local address = string.split(tuple[2])
local ret = {}
for _, v in pairs(address) do
table.insert(ret, {utf8.upper(v)})
end
return unpack(ret)
end]]
box.schema.func.create('addr_extractor', {body = lua_code,
is_deterministic = true, is_sandboxed = true})
idx = s:create_index('addr', {unique = false,
func = 'addr_extractor',
parts = {{1, 'string', collation = 'unicode_ci'}}})
s:insert({"James", "SIS Building Lambeth London UK"})
s:insert({"Sherlock", "221B Baker St Marylebone London NW1 6XE UK"})
idx:select('Uk')

incorrectly: when build_array is empty it changed it size to 1.

I think generally you're on track, and patch needs a careful
review now. Please solicit a review from Vova. For the
tuple_compare part, please ask Vlad to take a look - he did a lot
in this part of the code.
The only issue that surprised me is that you allocate a separate
tuple chunk for each key. I somehow thought that you're going to
use the same chunk for all bps tree entries, which I now realize
is impossible, since you'll need to store a chunk offset somewhere.
The problem is that slab alloc doesn't have a slab for tiny chunks
now - the smallest chunk is 24 bytes.
This is obviously an overkill for this scenario. Please fix the
slab arena accordingly.
There are lots of style comments, I'll place them on the branch.

I think the convention should be that a multikey function must always
return a table (a msgpack array for a C function).
It's OK to wrap every key into a table as long as it simplifies
the code (key part count is encoded automatically by struct port), but otherwise
I would stick to scalars.

this part is obviously incorrect. alter should not depend on
memtx_engine. And you don't need it at all. Please verify
key parts inside the trigger on _func_index space, then you don't
need to check for recovery state.

Please pass the allocator explicitly.
I don't understand why you force the user of this module to first
create a temporary buffer, then iterate over this buffer to create
hint objects. Why can't this function return an iterator right
away, and the iterator itself could return hint_t objects already,
not individual keys?

There is ER_ prefix, no need to add ERROR suffix.
The error code should reference index name and table name, not function name,
or all of this.
Imagine getting this error for a Lua procedure, it should not
require too many extra steps to nail down the cause.
There should be different error codes for different errors.
Resetting the original error is also a very unfriendly, please add
a ticket and a follow up patch to your todo list for stacked
errors. I mean, it's the last drop, how many times shall we step
on lack of stacked diagnostics before we add them?

These three places should use its own error code, not

Why not skip such keys when building a space format? What is the

Same here. I'm sure space format module can figure out that it
deals with a functional key definition and skip it if necessary.

I don't like it that key_def_new has become overly complicated
with collations, multikey and functional indexes. Perhaps we need
to introduce key_def_is_valid, similar to index_def_is_valid(),
but I need to think.

I don't get this, there should be two flags (is_multikey,
is_functional). How did this compile?

E.g. in :replace/delete part we don't need a persistent memory chunk: we need to
evaluate function and iterate over the returned keys to perform a deletion.
===========================================
key_list = key_list_create(old_tuple, cmp_def->func_index_func,

In case of secondary key it's definition consists of two parts (produced with
key_def_merge) - functional index key parts that refer to hint_t memory and
tuple parts are specified in primary key.

This code is really unreachable now. However this produce assertion error in case of

Generally yes, you get the idea, but I don't
get why key is const char *, and why you need key_sz at all.
The iterator can return hint_t right away.
Plus, you can merge key_list_create and key_list_iterator_create
into a single function, there is no reason why one has to perform
two calls instead of one.
