Support Arch(linux): aarch64 / x86_64 / ...
We don't call fsync when saving table/region metdata into manifest files, the data may be corrupted or lost in power outage etc.
udaf's input datatype related codes are almost the same, maybe we could create some attribute macro to auto add those fields to the struct, and extract some trait to derived?
We should create table automatically when insert some data, if the table is not exists. Just like mongodb.
This feature may be as an option enabled by default.
Currently in file engine.rs line 166
manifest
.update(RegionMetaAction::Change(RegionChange {
metadata: Arc::new(metadata),
}))
.await?;It should be executed when write lock is acquired and the region existance is checked below, otherwise the update action might be added more than once.
Move query::Output to avoid the client module be dependent on query module since the query module is heavyweight.
Coprocessor, as in TiDB and HBase or Stored Procedure in SQL, is a method to analyze data in local database and send it to remote node instead of send all data to remote node(and let remote do the analysis).
By using Coprocessor one can remove unnecessary communication cost and offload some computation to local node.
A Coprocessor using Python grammar can be much more friendly and customizable.
By using this rustpython project, a Python virtual machine can be embedded in the database system itself, this virtual machine can take any RecordBatch (which is essentially a wrapper for a Vec of Arc<dyn arrow::array::Array>) and cast it to a list of readonly PyVector(a custom type that impl some of the Python type's function). Also using a embedded vm means no unnecessary copy overhead will be introduce.
Then allow user to write a user-define-function in Python to compute and build a new PyVector.
A short example can be like this:
@coprocessor(args=["cpu", "mem"], returns=["overheat"])
def measure(cpu: vector, mem: vector):
overheat = (cpu > 75) & (mem > 60) # construct a new `PyVector<Bool>`
# here can also contains more complicated code i.e. complex predicates and branches etc.
return overheat Then the Vec<PyVector> can be cast back to RecordBatch and send for its original destination.
The Python Virtual Machines can be replace by directly compile to logical plan and execute therefore remove overhead of python virtual machine
.
Now the version column of storage engine is disabled by default and not yet implemented. Currently we have no plan to implement such feature, maybe we could remove this feature.
This is a tracking issue for implementing the StorageEngine::open_region() method.

For example, create a table:
CREATE TABLE monitor (
host STRING,
ts BIGINT,
cpu DOUBLE DEFAULT 0,
memory DOUBLE,
TIME INDEX (ts),
PRIMARY KEY(ts,host)) ENGINE=mito WITH(regions=1);
The host is a string type column, then query with it:
select * from monitor where host='host1';

Now the MitoEngine only support creating a fixed schema demo table, to really create a table, we need to create related regions using given CreateTableRequest.
CreateTableRequest, converting into RegionDescriptorCREATE IF NOT EXISTSwhen write aggregate diff, (https://numpy.org/doc/stable/reference/generated/numpy.diff.html)
the aggregate diff will sub the two value and panic "attmpt to panic sub overflow"
the value we has is :i8、i6、i32 、i64
when come to i64， the aggregate will panic of overflow(since the largest value type is i64)
so implement the value sub so to avoid the panic
When user creates a table as below:
create table system_metrics (
ts bigint not null,
cpu double default 0,
memory double default 0,
host string not null,
TIME INDEX (ts),
PRIMARY KEY(host, ts),
) engine = mito;
Then insert rows into table without explict columns or select * from table, the returned columns order is not the same with the order in schema:
mysql> insert into system_metrics values(1, 1, 1, "host");

to not pollute source codes' dir when running unittests from IDE.
AggregateUDF, Accumulator or create_udaf etc.Median function (like influxdb's) on top of it (but only works for i32 datatype)median to srcLocalFileLogStore has an internal entry id and always use that id to encode the entry, overwriting the id set by the user.
See file.rs
let mut file = self.file.write().await;
// generate entry id
entry_id = self.inc_entry_id();
// rewrite encoded data
LittleEndian::write_u64(&mut serialized[0..8], entry_id);Our storage engine requires setting the entry id to store the sequence of the region.
Current slice and replicateimplementation lost original data type.
Also fix this in DateVector/TimestampVector
We need to implement a MergeReader to sort the input batches from multiple data sources (memtables, SSTs), and a DedupReader to only retain the row with latest sequence, for same row key.
This job would be break down into multiple PRs:
use OrderedF32 and OrderedF64
A proposal: right now we have
timestampdata type in this PR, can we change the type ofgmt_createdandgmt_modifedin tablesystem_catalogtotimestamp?
Let me open a new PR to refactor all gmt_create/gmt_modified columns in system tables to Timestamp once your script table PR merged.

And we can't exit the datanode process by CTRL + C.
Both the table and the storage engine should support projection pushdown
Looks like ssl-dev should also be installed in order to compile project.

We should support AWS/GCP/Azure/AliCloud at first.
The storage engine needs an internal schema to represent its actual stored schema, which should contains the internal columns used by the storage engine. We might also need a projection helper or projected schema.
PrimitiveVector contains a primitive array, but the logical data type of vector may differ from it's internal array, for example, DateVector is represented by a Int32Vector, but the logical type is Date.
In fact, arrow's PrimitveArray::new accepts a parameter to specify it's logical data type, so PrimitiveVector should also have a logical data type.
A lot of useful window functions are not implemented now.
