Each ColumnReader consumes ReaderProperties.BufferSize memory
independently. Therefore, the bufferSize should be divided by the number
of columns to ensure total memory usage stays within the intended limit.

Add timestamp filtering capability to L0Reader to match the
functionality available in the regular Reader. This enhancement allows
filtering delete records based on timestamp range during L0 import
operations.
Changes include:
- Add tsStart and tsEnd fields to l0Reader struct for timestamp
filtering
- Modify NewL0Reader function signature to accept tsStart and tsEnd
parameters
- Implement timestamp filtering logic in Read method to skip records
outside the specified range
- Update L0ImportTask and L0PreImportTask to parse timestamp parameters
from request options and pass them to NewL0Reader
- Add comprehensive test case TestL0Reader_ReadWithTsFilter to verify ts
filtering functionality using mockey framework

1. Use blocking memory allocation to wait until memory becomes available
2. Perform memory allocation at the file level instead of per task
3. Limit Parquet file reader batch size to prevent excessive memory
consumption
4. Limit import buffer size from 20% to 10% of total memory

This parameter determines whether the returned value should be a copy or
a reference from the arrow array. The updates enhance memory management
and provide more control over data handling during deserialization.

1. Modify the binlog reader to stop reading a fixed 4096 rows and
instead use the calculated bufferSize to avoid generating small binlogs.
2. Use a fixed bufferSize (32MB) for the Parquet reader to prevent OOM.

# Main Goals
1. Create and describe collections with geospatial fields, enabling both
client and server to recognize and process geo fields.
2. Insert geospatial data as payload values in the insert binlog, and
print the values for verification.
3. Load segments containing geospatial data into memory.
4. Ensure query outputs can display geospatial data.
5. Support filtering on GIS functions for geospatial columns.
# Solution
1. **Add Type**: Modify the Milvus core by adding a Geospatial type in
both the C++ and Go code layers, defining the Geospatial data structure
and the corresponding interfaces.
2. **Dependency Libraries**: Introduce necessary geospatial data
processing libraries. In the C++ source code, use Conan package
management to include the GDAL library. In the Go source code, add the
go-geom library to the go.mod file.
3. **Protocol Interface**: Revise the Milvus protocol to provide
mechanisms for Geospatial message serialization and deserialization.
4. **Data Pipeline**: Facilitate interaction between the client and
proxy using the WKT format for geospatial data. The proxy will convert
all data into WKB format for downstream processing, providing column
data interfaces, segment encapsulation, segment loading, payload
writing, and cache block management.
5. **Query Operators**: Implement simple display and support for filter
queries. Initially, focus on filtering based on spatial relationships
for a single column of geospatial literal values, providing parsing and
execution for query expressions.
6. **Client Modification**: Enable the client to handle user input for
geospatial data and facilitate end-to-end testing.Check the modification
in pymilvus.

This PR includes the following changes:
1. Added a new task type to the task scheduler in datacoord: stats task,
which sorts segments by primary key.
2. Implemented segment sorting in indexnode.
3. Added a new field `FieldStatsLog` to SegmentInfo to store token index
information.
